Customer Ratings & Reviews

I was incredibly excited to review the Sennheiser Momentum True Wireless 4 earbuds, and for the most part that excitement has stayed pretty high after a week with these earbuds. I've reviewed a lot of earbuds over the last few years and I would easily place these at the top in terms of comfort and sound quality. While they are not perfect, I don't think anything is a dealbreaker but I'll detail below. #First impressions# Unboxing was pretty unexciting for the Sennheiser Momentum TW4s. I tend to think that top brands sometimes spend less time thinking about cool packaging because they feel their product speaks for itself. That might be true here. There aren't any cool little pouches or even a decent organizer tray included for the extra earpads and stabilizing loops, but I have a nice little bin for this stuff in my desk drawer. The actual case for the headphones has a VERY cool feel, a cloth/nylon type covering. I immediately set it on my wireless charging pad and let it wake up and top itself off. #Pairing/App/Extra Features# Pairing was super easy. The earbuds won't wake up until they've been connected/placed on a charger, which isn't that weird these days. Once that was done, they easily connected to my S22 Ultra. I downloaded the recommended Smart Control app and found it to be functional if a little light on features. No volume limiter, no Atmos. After that initial impression I've ended up deciding that the app allows for pretty serious customization for the earbuds beyond what other brands are including. You can customize normal stuff like the EQ and ANC, but also can change the touch controls and easily change the codec to maximize your sound quality. I found the Lossless audio worked better with my phone as the S22 Ultra wouldn't connect at 24bit as indicated with the "High Resolution" option. I really like that they give you a battery protect mode as well. Too many of these earbuds get worn out in less than 2 years. #Sound# Fantastic sound quality. A very warm sound that was surprisingly open for ANC earbuds. In the aptX Lossless mode, I can pick out some details that bluetooth compression usually crushes especially with acoustic music. Bass is exactly what I hope for in a set of higher end earbuds - tight, hard-hitting, but not tuned to be loud enough to drown shortcomings. Overall the sound is just exactly what I was expecting from my experience with traditional Sennheiser headphones. These stand quite a bit above the other premium earbuds I've used in the last few years. #Detractors# I've already mentioned the lack of an included/integrated organization system for the extra earpad sizes and stabilizers, although that is kind of a minor deal to me. A bigger problem is the size of the case itself. It's unnecessarily huge. Out of 5 earbud sets that I've used recently, the Sennheiser case has the hardest time fitting in my pocket with a single car keyfob alongside it. It's the thickest case of the earbuds I have on hand, and close to the widest and longest. The earbuds themselves are large but still comfortable, so that explains some of the case size. Problem is, the case is large enough that it's made me consider continuing to use earbuds I like less when I go to the office just because it's so big in my pocket. That's despite the fact that the Sennheisers are more comfortable, sound better, and do a much better job at noise isolation than any other earbuds I have for the office environment. For those with bigger pockets or another way to carry the case (or no car keys) then I'm sure the case is fine. I'll attach a photo with this review comparing to others I have. #Conclusion# An excellent set of earbuds at a premium price but with the premium comfort and sound quality to justify the price. Just a bit big in your pocket.

I love these earbuds but they are overpriced and the charging case hinge is very flimsy.

Sennheiser has been around since 1945! The German company has been one of the most renowned audio manufacturers for the last century. The engineering part of their audio continues to impress the most, yet the build quality of their products also never disappoints. From their over-the-ear headphones and earbuds to their soundbars, you will more than likely be impressed if you purchase a Sennheiser product. I've been an earbud enthusiast for a while now. I've had an embarrassing amount of earbuds throughout the years. Sure, Apple Earpods made wireless earbuds mainstream. Still, the true "audio enthusiasts" knew that the original Sennheiser Momentum True Wireless won the best sound category when the masses were buying the Earpods. I've owned the originals, the second gens, and now the fourth gens. The only reason I skipped the third gens was because I was so happy with the 2's. They had become my favorite earbuds of all time (and I've tried so many). However, I tried the 3s and thought they sounded as fantastic as ever. Before the fourth gens, it was a close call between the Bang & Oleson Beoplay Exs and the Momentum True Wireless 2s. Regarding sound, only a few other buds can match the audio fidelity of those two products. The Momentum 4s have a crispness that is very difficult to get in an earbud. It's the closest thing to an over-the-ear headphones sound you can get with buds. Not only that, but it's customizable if you like to tinker with the equalizers. The app that accompanies the buds is called "Smart Control" and has been excellent for the most part. There have been some issues with the app connecting the buds. I had problems with the second version, losing connection with the app and having to repair them several times throughout ownership. By reading and watching early reviews of the 4s, the app may have suffered from some issues in the first months of release. However, I have not had any connection issues (given that there was a firmware update after setting them up). The firmware update went smoothly and didn't take multiple attempts, like some apps. Once connected, the app has many settings with which to tinker. I love the fact that you can create your own. Sound is very subjective, so it makes the sound much more enjoyable when you can customize it to your preferences. There's also a "bass boost" or a "podcast" toggle. The bass boost is perfect for hip-hop. It doesn't overload the bass but turns it up to what most hip-hop producers wanted the sound to be when they recorded it. The podcast toggle reduces bass altogether and emphasizes the voices - which is welcome for those who listen to podcasts. Regarding the ANC, the Sennheiser's are up to par regarding noise canceling. They've been hit and miss in the past, but the 4s seem improved, even though they can keep going. I love the "anti-wind" setting, perfect for walks or runs in windy environments. Speaking of being out and about, the transparency level is also customizable from anywhere, from low to high and in between. This isn't a feature I use much, as I love to go out and run with sound, but while riding your bike, walking on the roads, or enjoying music somewhere you'd like to hear your surroundings, I think the 4s do an excellent job. The Earpods are the standard when it comes to transparency but lacks audio fidelity, so Sennheiser's audio fidelity makes up for the bit of difference between the transparency mode. There are also touch controls that are extremely easy to use. Surprisingly, the touch controls are intuitive when the buds are tiny. I chose to stay with the default controls, but that is another aspect that you can customize if you wish. As with any earbuds, one of the most critical steps you need to take to ensure the best sound is the fit. If there is a lot of sound leak from the buds, the sound will suffer greatly. Sennheiser's app is helpful with that because it has its own "fit test" built in. It's straightforward to use and will let you know how much sound leaks. These buds do give a very tight seal, which is excellent. For some, however, this may feel uncomfortable, as if your ears are plugged or a feeling similar to when you're in water, but to me, it's not something that bothers me after choosing the correct sized tips. One of the coolest features of these earbuds is something that I haven't seen any other company do—the Sound Zones. This will automatically give you "sound profiles," depending on your location. If you're at work and need transparency mode on, it will use geolocation to know you're at work and automatically turn transparency mode on. That's pretty cool. The idea of not needing to tinker with the settings every time you go to work should sound welcoming to all. Battery life is outstanding, too. 7.5 hours is expected per Sennheiser, and from the first few days, I purposely didn't charge them; they lasted me around 7! And that's at higher than normal volumes and with "bass boost" turned on most of the time. With the case, you can get around 30 hours. PROS: * Excellent sound quality (rich, crips and detailed) - I'd say it's tied with Beoplay EXs * Great seal ear tips with different size options * Battery life * Wireless charging * Smaller bud size CONS: * Transparency and ANC could be better * Call quality should be improved * Can be uncomfortable to some or take trial and error to get the perfect fit

It is unfortunate that I have to write a negative review. I literally spent two weeks reviewing different earbuds. I settled on Sennheiser due to the good reviews and the noise cancellation as well as the warranty. I have had Momentum 4, for four months now. From the first week there has been disappointment. Initially the volume was lower than desired, I wrote that off to being ear buds, not over the ear headset, so I said I can handle a little less bass. Then the issue with fit. The ear buds keep slipping, have to keep pushing them back in my ears. It's no fun having the catch an ear bud sitting at the poker table. Then finally the quality of sound. I am sitting and listening or walking and listening and have my phone in my pocket and I get static or it cuts out. This is less than acceptable. I finally have enough and today, I will take them to the store to see what they can do, exchange or return. But even though I did my research, unfortunately the Sennheiser-MOMENTUM True Wireless 4 Earbuds, and much less than optimal for every day use.

When you get the new Momentum True Wireless 4, you won’t necessarily notice any difference between the outgoing True Wireless 3 earbuds these replace. Even the charging case looks the same. The True Wireless 4 are an evolutionary upgrade, not a revolutionary upgrade. That’s actually a good thing. The True Wireless 3, which I’ve had for the last couple years are excellent earbuds. Sennheiser has a characteristic signature “flat” sound. Headphones, which are too bright or too base driven can cause listener fatigue. Sennheiser, has a sound which is neutral which you can listen to for hours on end without fatigue. Download the Smart Control app and you’ll find sound settings to customize the earbuds to your personal tastes. The TW 4’s offer a number of upgrades over the TW 3's. The antennas have been redesigned to improve stability. They now use “dynamic-load-switching,” which will improve the consistency of the sound quality and the closest earbud to your cellphone is always connected but the earbuds can switch to maintain the best sound. The TW 4’s will have Auracast which will permit audio at the same time through separate channels to listen to music and receive notifications simultaneously at Airports or Stadiums. You’ll also be able to stream to two pairs of compatible earbuds from one device. These are the worlds first earbuds to be released using this new technology, making them virtually future proof. The new TW 4’s also have the new Qualcomm S5 Gen 2 Processor and Snapdragon Sound Technology. Why is this important? You’ll be able to stream losslessly from 16-bit 44kHz but with an update (to be released) you'll be able to stream at 24-bit 48 kHz. The TW 4’s also support Bluetooth 5.4, aptX Lossless and LE Audio (but you have to have a device which supports them) If you own an iPhone and use Apple Music, you’ll be limited to AAC at 16-bit. If you subscribe to other premium Streaming Services like Qobuz or Tidal you’ll get the higher bit-rate. The TW 4’s include all the high-end Codec’s, like SBC, AAC, aptX, aptX Adaptive/Lossless and LC3. I can’t honestly hear the difference between Codec’s myself. My TW 3’s suffered catastrophic battery failure in the same earbud twice, requiring Sennheiser to replace them. To their credit, they did so outside the warranty, which is a generous 2 years. Sennheiser has reengineered the battery in the TW 4's so they should be much more reliable. NECESSARY DETAILS: - The TW 4’s are IPX-54 rated, which is water resistant, but you can’t shower or swim with them. - There are 3 microphones per earbud for calls. - They use touch controls to pause music, raise volume, skip songs, answer a call. - Included in the box are four sizes of ear tips, 3 wing sizes, to customize the fit to your ears. - With ANC on, you’ll get about 7 hours of playback before needing to charge them, without ANC Sennheiser claims 7.5 hours. And a quick 8 minutes of charge, you’ll get an hour of play time. - Sennheiser now lets you charge the batteries up to 80% increasing the useful life of the batteries. - The charging case will give you up to 30 hours of play time. - The Smart Control app is comprehensive. You can create custom EQ settings, control the Adaptive ANC/Passthrough and even reprogram the touch options on each earbud. With sound personalization, you can intelligently calibrate a custom audio profile from a sophisticated analysis of your reactions against a series of sound samples. It works GREAT! There’s a 5-band equalizer, if you’d prefer to just slide your way to the sound that fits your listening needs. COMFORT - SOUND - ANC - CALL QUALITY: The large soft silicone ear tips fit me best, with medium sized wings. Sennheiser changed the ear tips slightly. They’re more comfortable. Better comfort means you can listen longer, without fatigue. These puppies are very comfortable for long hours of listening. Sound trumps ALL, when it comes to headphones. I’ve read some reviews where people expected the new TW 4’s to be mind-blowingly better than their predecessor. The TW 3’s were already great earbuds. The new TW 4’s are not radically different sounding than the TW 3’s. But that’s good. Sennheiser is long known for making headphones with a signature sound that is honest, realistic, and honors the way the sound was recorded. Bass is strong not boomy. Mid-range is natural and upfront. Treble is not harsh and won’t cause listener fatigue. There are pieces I listen to test new headphones. Camille Saint Sans - Organ Symphony. When the organ hits, you want to feel like you’re in a concert hall and feel the deep bass of the organ resonating. The TW 4’s did that with great gusto! Mason Bates, Alternative Energy – Xingjiang Provence is powerful and the TW 4’s did an amazing job. Libera’s, For the Future, which can sound harsh on lesser earbuds, presented vocals which were smooth and warm. The Piano Guys, A Thousand Years, which is a very dynamic workout for headphones and the TW 4’s did an amazing job. Use the right ear tip and you may not need to use ANC. Passive noise cancellation on these is really good. But there will be times in loud environments (crowded coffee shop/airplane) and you’ll need ANC. ANC on the TW 4 is excellent for my needs. Passthrough works well if you need to hear sounds from outside (running for example) where passthrough can save your life. Call quality is one area Sennheiser could step it up a bit. In a quiet room, it works fine. Move into a noisy environment, and the TW 4’s fall short. It’s not bad, but it could and should be better with 3 microphones per earbud. Overall, I’m REALLY happy with the TW 4. They may not be revolutionary, but they offer all the great things the TW 3’s offered and add in better batteries, better battery management, the newest future proof technologies, great sound and even better comfort. Should you buy them? Yes, even if you already own the TW 3. To me, the new True Wireless 4 is a great step forward in Sennheiser’s best consumer earbuds! Just don't expect earth-shaking differences. It's not easy to make something already great better. But Sennheiser did just that with the TW 4. Yes, they did!

This is now my 12th set of BT wireless earbuds.  The third that supports BT 5.3. Why so many; they keep getting better.  I had the Sennheiser Momentum 3 True Wireless. And I thought they were sensational.  Since BT 5.3 became available I have these Momentum 4's, Denon's PerL Pro 339s and Soundcore's Liberty 4 NC.  These Sennheiser's and the Denon's are priced within $50 of one and the Soundcore's are 1/2 the Sennheiser's price.  The Sennheiser's come with a 2 year warranty, the others a single year.  Before I did any testing I made sure that I had the current firmware for each and I broke the Sennheiser Momentum 4 overnight with Tara Labs Noise burnin, they lasted 7hrs, not quite the 7.5hrs promised and only 15m more than the Momentum 3s. Sennheiser claims the 4s have 30h battery life (7.5h+22.5h from charging case).  Both the Sennheiser's and the Denon's have a custom sound profile, where you listen to sounds/music to create a personal profile.  The Denon 'test' tells you more about what they are doing than the Sennheiser 'test', the Sennheiser seems to incorporate more dealing with volume, the Denon more with frequency ranges.  In either case I prefered the custom profile to the default.  Both the Sennheiser and the Denon's have a custom 5-band EQ.  The Denon's can be combined with the custom profile, with the Sennheiser it's a one or the other proposition (too bad). The Denon's have an Immersion Mode which is said to improve the 3D soundstage, I try this later. Soundcore has a 8 band EQ and a similar sound profiling tool which is more like an audiologists test tool (can you hear this tone, how loud is this...) and their EQ can be combined with the custom sound profile.   I listened to all 3 pairs from an iPhone 15 pro and an Android 13 Tablet w/Poweramp. All 3 earbuds have active ANC and all support a form of transparency (you can hear someone speaking to you with the earbuds on).  The Sennheiser and the Denon's ANC performed adequately and Soundcore was not nearly as good. All 3 earbuds seemed to weigh about the same, all claimed similar battery life (7-8h).  The Denon's are physically the largest, and the big part goes up, the Sennheiser's and the Soundcore's are designed to hang on your ear with the big part down.  I found the Sennheiser's had a better fit when moving vigorously, but when just seated the Denon's were less noticeable (easier to wear all day).  The Soundcore's moves around a bit requiring me to reseat them occasionally.  No clear winner, easy to wear any of them on a long flight.  I tried all 3 next to a running A/C unit to test the ANC none were perfect still a some "engine" noise the Soundcore was the worst of the 3, a toss up after that. Then I listened to Boston's first album; switching between the 3 earbuds now and then.  Then Pink Floyd's Dark Side of the Moon and Foghat's Fool for the City,  A little Warren Zevon, Queen, Rush, Yes and Zeppelin.  And I went between my iPhone and my Tablet (w/aptX), I tried to match sound levels, which was harder than I'd anticipated.  The best bass across all the music was Sennheiser Momentum 4's. It was a little punchier, the Denon's were a close second. And the Soundcore's bass was similar (but a bit thinner) on the iPhone but lost out noticeably from the Android Tablet.  The highs from the Sennheiser's were the cleanest, making horns sound the best. This is where the Soundcore's biggest weakness showed up, the ethereal voices on DSOTM didn't float in the same way they did on the Denon's and the Sennheiser's. The spoken words on the Denon's sounded better with their Immersion mode enabled, the Sennheiser's were a close second.  From my iPhone I thought the mid's of the Sennheiser's were slightly cleaner than the Denon's. But the other way around from my tablet (this surprised me and I repeated my listening tests).  Clearly the Sennheiser's sounded better from my iPhone and the Denon's from my Tablet (same source material). The Sennheiser's offer something called sound zones, which can be set/changed based on GPS locations, so you could have a profile for the office, your home, the ballpark, any place you frequent.  An interesting concept that I really didn't get to test. But the best implementation of a feature was the Sennheiser's transparency setting, so that when you talk with someone, how you can hear them, it just lowers the volume of the music.  I can think of circumstances where I might use one or the other (mute), but it's nice to have a choice (I'd definitely program this for 3 taps and hold).   The Sennheiser's and the Denons's are both exceptional earbuds, in many cases it was hard to tell them apart.  From an iPhone I'd say the Sennheiser's were the winner and from and Android tablet (aptX) the Denon's were my preference. But given both of these are twice the cost of the Soundcore's the Soundcore's are the best bargain.  After listening for several hours, I found all of them very comfortable.   Sennheiser has improved upon Momentum 3 slightly, but I would not spend $100 more to get the 4' over the 3's.  IMHO the 3's and 4's are one of the best sets of earbuds that you can get today (if you have an iPhone). The Denon's are great, but possibly a little overpriced compared to the Sennheiser Momentum 4s, I don't think I'd spend more to get them.

These high-end true wireless earbuds have it all! Adaptive Noise Cancellation, Transparency Mode, wireless charging, long battery life, quick charge for when you forget to charge the case, amazing sound, etc. While they look and sound similar to the prior TW3, they have improvements in the batteries and the connection codecs that make the guts better than before and are more future-proof for improved connections. Highlights: * Improved battery for longer and more reliable use. * Updated Bluetooth codecs for better sound and future-proof updates. * Better active noise cancellation. * All of the same excellent features of the TW3 including wireless charging and comfortable wearing. * Multi-point connections. * Flexible customizations via the Sound Control app. * Auto-pauses the music when Transparency Mode is on or one bud is removed. * Improved ear tips are easier to clean. Room for Improvement: * No major differences visually between these and the prior TW3. * Still a tad chunky. Setup: Extremely easy to set up with a combination of BT Classic and BTLE connections to set everything up quickly and easily. Once connected to your device of choice, use the app to customize the sound profile, the function of taps on each bud, update firmware, etc… Everything seems easy to understand and apply. Usage: Take the buds out of their case and put in your ears. They connect quickly and easily and resume whatever sound profile you last used (or one based on location if set up that way). Defaults are to have the adaptive ANC on normally and then a single tap on the left earbud will pause playback and turn on the Transparency mode - a feature I really like. The audio quality is superb by default but can be tweaked as much as you like. As an owner of the prior model (TW3), the sound seems really close. Most of the improvements in this TW4 over the prior TW3 are related to the batteries and Bluetooth connections, so there shouldn’t be much of a noticeable difference in normal day-to-day use. The upgraded batteries now last longer, charge faster and are more reliable in the long-term. I personally had issues with the TW3’s batteries and needed to replace my buds under warranty, so I appreciate the change in batteries with the TW4. The upgraded Bluetooth codecs claim to future-proof these earbuds so they can be updated later to work with Bluetooth connections that are more efficient, have higher quality sound and new sharing features. For now, though, they work just as great as before and may be even more robust connecting to your devices. Putting the TW4 side-by-side with the TW3 is hard to tell the difference. So if you tried and liked the TW3, this TW4 is everything you loved but with better batteries and newer Bluetooth connection codecs. Upgrading to the TW4 from the TW3 is not a slam-dunk, but if you value the future-proof connection ability of the TW4 and/or had issues with the TW3’s batteries, these would be a nice update. By the way, the ear tips have an updated design that makes them easier to clean if some ear wax gets in there (which they always tend to do). Overall: Everything that the amazing TW3 had in terms of fit, function and sound quality, but with improvements in the batteries and updates that future-proof the Bluetooth connections. Despite their chunky look, these earbuds are comfortable to wear for hours, sound amazing and the ANC and Transparency modes are top-notch. If you’ve been waiting for a time to jump in to Sennheiser’s best true wireless earbuds, these are for you!

TLDR: Laid back & easy going. ANC needs work to make them excel. FEATURES USB-C / Wireless Qi Charging Capability Active Noise Cancellation Up to 7.5hrs of Playback per Charge / 30hrs with Docking Station Latest Bluetooth 5.4 support with Auracast and LE Audio support Supports Lossless Audio Playback INTIAL CONFIGURATION Initial configuration via the Sennheiser app is a unique experience with Sennheiser’s twist on the market. It works well for the most part but is not as user-friendly and convenient as Sennheiser’s competition. One exceptionally nice feature of the Sennheiser set-up process is the test fit and initial tuning built-in to the app. The app helps the user get a better initial experience with their purchase, guiding them through a series of audio clips, helping to tailor the sound profile to his or her liking. The app plays a combination of instruments, representing the low, middle, and upper ends of the listening spectrum (not absolute limits, just the sweet spots). The user merely adjusts a series of sliders to make the pre-selected track sound to them. It is simple and easy and goes a long way to help get the initial set-up dialed in, reducing the amount of fiddling and tweaking. One thing I don’t like is that Sennheiser requires you to create an account with them to use and create the tailored sound profile described above. Failure to do so renders the customized sound profile useless. This is an unnecessary way to get people to sign up and is the ONLY vendor I have that requires you to sign up and register your product to activate the profiling feature. Out of the 9 other vendors of headphones and ear buds I use, none of them cripple their apps and product in this regard. I’m sure Sennheiser will claim that doing it this way carries your preferences from one device to another, but for those like me, my sound preferences on my Android phone are different than my iPad. In keeping with the audio configuration, another huge miss is the adjustment process after initial set-up. The app does not allow you to configure your sound preference on the fly. To make changes, the app stops your current playback and resumes Sennheiser’s pre-selected track again. You make your tweaks and once confirmed your playback resumes. If you don’t like your changes, you must repeat the whole process over again. I would much prefer to make on the fly sound adjustments with your currently playing track versus bouncing back and forth. While Sennheiser does allow for on-the-fly adjustments via a 5-band equalizer, having both options seems redundant and unnecessary. AUDIO QUALITY As with any audio product, perceived audio quality and reproduction is always subjective and often controversial. In my use of the product, the Sennheiser’s are the Jeff Spicoli of my current ear buds and headphones (kudos to those of you who instantly recognized the old-school 80’s movie reference). The True Wireless 4’s, much like the iconic movie character, are easy-going and laid back without a care in the world. These are, by far, the most laid-back and warmest of any ear buds I have. Not that it is a bad thing. It is something the user must hear for themselves, especially if auditioning them side by side with a competitor. While I have several sets of ear buds and headphones that are tonally much more neutral than the Sennheiser’s, there is something to be said for the TW4’s audio reproduction. It is soothing and not brash or harsh in any sense of the imagination. Not to say they are inaccurate or lazy, they are just warmer and don’t go out of their way to be the ultimate in sonic clarity. It is a refreshing change. One area that I need to give Sennheiser credit for is their use of the entire audio spectrum. The TW4’s can extend down to the limits of the audible spectrum at 20Hz. Many leading competitors’ products only go down to 40Hz. The added depth and dimension of the TW4’s are immediately noticeable. While the Sennheiser’s roll off after 10kHz, as do most, they can still hang with the best at the top and bottom end of the audio spectrum. Again, kudos to Sennheiser. If you are bass head, these deserve a look. No other ear buds I have in my collection can reach the lower limits as well as the TW4’s. NOISE CANCELLATION This is the one area the effectively holds the True Wireless 4’s back compared to its competitors. These ear buds are unable to effectively drown out ambient noise. Noise from a room air conditioner, mini-split, plane, car, etc. just isn’t subdued enough. I will fully admit that when I travel, there are times that I don’t want anything playing in my head. Times when I just want to put in my ear buds or put headphones on and let them drown out the world around me. These Sennheiser’s can’t do it. They can muffle it to an extent, but compared to nearly ALL Sennheiser's competition, their ANC technology is sub-par. However, with a good fit, playback can be enjoyed, and outside noise is often dismissed and/or diminished, being lost in the background. But it is not forgotten as it will immediately rear its ugly head as soon as a quiet passage in playback comes on. STREAMING QUALITY I experienced no issues using the TW4’s with either my iPad or my Galaxy smartphone. Bluetooth transmission distances easily reached at least 20 feet with no dropouts, even when listening to the high-resolution audio transmissions. What is worth mentioning is the quality difference between the Android and the iPad. The Sennheiser’s use Qualcomm’s S5 chip. This chip, or its ancestors, are included with several Android-based phones (especially from name brand manufacturers). Because of this, Android users will see the biggest benefit of Sennheiser’s use of Lossless and Bluetooth Adaptive AptX codecs. My Galaxy phone easily allowed me to switch between Bluetooth quality streams, where my iPad must make do solely with Apple’s AAC codec. I know some will point out that the AAC codec can supposedly rival the other lossless codecs, but in my experience, in this implementation, it does not. This AAC implementation is lossy, hands down. CALL QUALITY The TW4’s call quality is equally as good as any other premium player on the market. Call quality has progressed far enough that it is hard to pick which manufacturers do the best job at audio call clarity. The Sennheiser’s are no exception. Call quality was clear and intelligible with no dropouts. Callers commented that I was easy to hear and understand with decent ambient noise cancellation. FINAL THOUGHTS Even with their faults, I am thoroughly enjoying the TW4’s. I find myself using them more than other headphones or ear buds in my collection. While I, at times, want the best of the best in terms of accuracy and transparency, there is just something that keeps bringing me back to the Sennheiser’s. I find their laid back and easy-going nature soothing and stress-relieving. When the TW4’s were initially released, they did not support LE Audio or Auracast. These features were added later via a firmware update. I say this because I’m hoping Sennheiser continues to refine their firmware over the product’s lifecycle and improve the noise cancellation. It certainly needs it. If I were a frequent traveler on public transportation (whatever it may be, bus, subway, plane, etc), especially if I owned an iPhone, these would not be my first choice in ear buds. There is too much left on the table that Sennheiser’s competition does better. As an Android owner, these would absolutely be toward the top of my list, especially if I used them most of the time in ambient noise-controlled environments. RECOMMENDED

I am a little conflicted while writing this review, because on one had these are very good earbuds, but on the other, they are not. I will do my best to explain. First of all, from the moment you take these out of the box you know they are a premium product. They are built well and they thought of a lot of design elements such as wrapping the case in a gray mesh cloth so its softer to touch. Including an array of different size ear tips and wings to help you get the proper fit. Getting them paired to the app was a fairly easy process and there are a lot of things you can try in the app to enhance your listening experience. For starters they have a 5 band EQ, I would hope they would have at least a 10 band, but 5 is all you get. There is another option where you can tune the buds to “your sound”. Basically they play a bunch of clips of music and you adjust the levels of duitars and drums and such to supposedly tell the ear buds how you like music to sound. Then you have a large graph show up on the screen where you can supposedly fine tune that sound. I found this to not work that great for me. First of all, the style of music they have you tune the buds too is not even close to the style of music I listen to. So, I am unable to tell it how I like to listen to the style of music I like. Secondly, when you go to fine tune them, you still can’t listen to one of your songs, you have to listen to a predetermined track to adjust them. Then go back into your music service and listen to something you want to. Then go back to the fine tune and try to adjust. Then go back to your music app. Its quite a maddening experience. So, for that reason, I just stuck with the 5 band EQ and I was able to get much better sound that way than messing around with the personalized experience. Next, I will get into the fit, which is where I have the biggest problem. Whenever I put these earbuds in it takes me a very long time in order to hit the sweet spot where most of my ear is sealed so I can get the best sound. I tried all the different tips, all the different wings in all the different combinations and I still struggled every time I put these in my ears. I like to wear these when riding my bike so I was excited to try the wind noise blocking setting on them to see if it would help. The problem was that I could never get a great seal or fit in my ear so wind was still getting in. Maybe including some foam tips would help to get a better seal in the ear canal instead of the typical rubber ones that don’t really conform to your ear easily. On the occasions when I was able to get a good seal on the ear, these sounded fantastic! So that’s why I’m a little conflicted in my review. Under the right circumstances and in the right ears, these sound amazing! I was getting a good balance of bass, mids, and treble and everything sounded very crisp and clear without being too overpowering in any aspect. I mostly played hi-res music files from my phone, but I also tried Spotify and that also sounded great. I found the noise reduction to be pretty much on par with most other earbuds. It does a good job of blocking out a lot of noise around you, but you will still be able to hear things during silence in your music. I found all of the touch controls to work very well also. You can set them up in the app to pretty much do anything you want then you tap the earbud one, two, or 3 times and also when you hold your finger on it for a couple seconds. So you can easily customize these to your liking. The battery life was fantastic as well. As usual, the case also has a battery in it so it will charge the earbuds whenever you put them back in the case (as long as the case is charged). The case also has wireless charging which I love, so you don’t have to mess around with cases. So, overall, these earbuds are great and they sound fantastic. Just know that you may have a problem getting a good fit for your ears and that may cause you to struggle with them.

My music listening experience has been completely changed ever since I got the opportunity to try this Sennheiser MOMENTUM True Wireless 4 Earbuds. The design is the first thing we should talk about, You can tell they're well made and long lasting thanks to the sturdy construction and stylish black finish. Additionally, they come with multiple ear tip sizes, allowing you to discover the ideal fit for your ears a major benefit when it comes to comfort you can check which ear tips suits to your ear using the App, Let us move on to the way it sounds which is absolutely astounding. The sound is clean, well balanced, and sharp the bass is strong without being muffling even at the higher frequencies. Without a doubt, the MOMENTUM 4 Earbuds provide the most immersive listening experience, whether I'm enjoying my favorite rock songs or losing myself in a classical masterpiece. For me, the active noise cancellation is one of the highlight features. It's as if you can enter a peaceful cocoon anywhere, even in the most hectic of places, like a crowded cafe or the flight Journey. My favorite part is how it eliminates all background noise, so you can concentrate on your music or podcasts. Not only that, but these earbuds have an excellent battery life. You won't often run out of juice, even on lengthy journeys or busy days out and about, with up to 30 hours of playing with the charging case and 7 hours with earphones. I can quickly return to listening to music whenever I need to charge because the case offers rapid charging. I didn't have to fiddle with my phone at all to change the volume, skip songs, activate active noise cancellation, or answer calls thanks to the earbuds' responsive and user friendly touch controls. Additionally, I can rest assured that even light precipitation or perspiration won't damage them during my workouts or outdoor adventures because they have an IP54 rating for water resistance. From a user's perspective, the Sennheiser MOMENTUM True Wireless 4 Earbuds are amazing. Impressive style, first rate sound, and user-friendly functions come together to form the best listening experience ever. In short, these are top-notch wireless earbuds that you should look into buying one.

[PROS] Sturdy build quality: The case and earbuds themselves are thick, but not overbearing. The case is durable for portability and covered in fabric that is pleasing to the touch. The earbuds themselves are plastic, but still with a premium feel to them. Strong audio fidelity: Out of the box, I was highly impressed with the quality. Before tuning, the default profile seemed to have a higher emphasis on vocals in my opinion. Yet, I was able to adjust them to highlight the nuances of different genres that I would listen to. Excellent Transparency (Ambient/Hear-through) Mode: For me, this an extremely important feature. I want to be able to control the amount of outside noise I let in just as much as I want to filter out the external environment through ANC. Through the Smart Control app, I'm able to use a slider to amplify my environment to my liking instead of the typical three low, medium, and high options. It works so well that the performance has exceeded that of many over-the-ear headphones that I own. Strong Battery Life: I'm able to get hours upon hours of usage out of my earbuds regardless of which mode I have enabled. I'm usually using the Transparency mode at its maximum level so I can be present around others, but listen to other things as needed. What's even greater is that I'm able to cap the charge level at 80% to extended the longevity of my earbud's internal battery. Plenty of Customizations: The Smart Sound app allows for an ample amount of customizations to be used with the Sennheiser Momentum TW4 Earbuds. The included presets do their intended genres justice, but I utilized the sound personalization tool to add more distinction to what and how I listen to music. Decent Microphone: The microphone is satisfactory. The playback of my speech is flat, but very clear. There's no muffling in my voice, and the listener can hear it just fine. - Additional Ear tips: This may not mean much to some, but Sennheiser does include 4 ear tips sizes instead of the standard three. I found myself most comfortable with the largest sets of earbud tips and could wear them comfortably with prolonged use. [CONS] Disappointing Active Noise Cancellation: The active noise cancellation isn't as strong as I would have hoped for it to have been. It does a moderate job of blocking some of my environment, but there are occasional noises that seep in. App Quirks: For the most part, the app is straightforward and easy to understand. However, I did run into multiple issues with attempting to conduct the "Fit Test". The test failed for me 5 out of 6 times. Each failure recommended me to change the ear tips and adjust the earbuds. Despite doing so, it was not advancing me to the next stage. It finally worked the next day, but I didn't do anything different. The Fit Test does come off as gimmicky. [CONCLUSION] In this form factor, the audio quality is top tier. The Momentum TW4 provides a wonderful audio experience. Because of the performance of the ANC and microphone, it's not the end all be all for me, however, it was become my daily driver for multiple situations.

A couple of decades ago, I remember going to a store to pick up my first audiophile headphones. These headphones lasted for several years and they have always set the bar for those who followed. The brand? Sennheiser. It's 2024 and Sennheiser is back in full force with some excellent products. Like the Momentum 4 ear buds I've gotten and let me tell you, the company still knows how to make excellent hardware. The box doesn't look flashy or out of this world, but if you take some time to look at the back of the box, you should get an idea of what these babies can do. They come jam-packed with the latest tech: Bluetooth 5.4, Adaptive ANC, LE Audio and Auracast. The list is much longer, but you get the idea. One thing caught my eye though and it's not necessarily something you'd look at. Sennheiser offers 2 years of warranty on their Momentum ear buds. To me, that's a clear sign that they care about their customers and the continued quality upkeep of their products. In the box are the ear buds in their case, a short USB-C to USB-A charging cable, a set of replacement tips and a separate sleeve with 3 other sizes of tips. There's a quick manual to get you started as well as other pertinent documentation. The case is covered in a textile wrap. I love the idea, but you have to ask yourself how long until it turns into a dust and dirt magnet. The buds look rather big at first glance, but once in your ear, they are very comfortable to wear, which is mostly due to the shape which locks them in place in your ear with a slight twist. Once connected and hooked up to your device (I would recommend to use a smart phone first as that seems to be the default platform for ear buds these days), you will be welcomed by some of the clearest, smoothest sound you can get. The frequency range is amazing with clean highs, wide mids and round and bouncy bass. Some might dislike the chimey highs, but you can change all of this with the dedicated companion app. I spent several hours listening to various genres and I couldn't find a track that would show any deficiencies in that area. On top of having a beautiful sound, the comfort is also there, even after hours, your ears don't feel like someone went to town with a cheese grater on them. Another great aspect is the amount of customization you have to make the sound truly yours. The EQ works very well and you can even tweak the sound rendering to a higher frequency and bit size or activate other helpful options. The active noise canceling tech used by Sennheiser is one of the best on the market and switching it on and off is as easy as tapping your ear bud which doesn't interrupt your listening experience, but allows you to listen to someone talking to you. If you're a casual user, you can also simply apply the presets and not ever have to dive into the belly of the beast, without ever sacrificing quality. The battery charge is close to what it claims, around 30 hours (I clocked in about 26 hours). Charging doesn't take very long either, you can get a good amount of charge in less than an hour. Bottom line: Sennheiser is back, making great sounding and high quality audio available for everyone. The price tag is right where it should be as these ear buds are better than most other brands in the same price segment. If you love music and you want some ear candy, go for it and by the Momentum 4. Excellent product!

The Sennheiser MOMENTUM True Wireless 4 earbuds are a premium set of earbuds. The cloth covered case with the signature Sennheiser logo on top screams premium, and is also capable of wireless charging. Battery life is exceptional. I was able to go six hours straight with ANC on and switching between podcasts, music, videos, and phone calls. After all that, I was still at 20% charge. After about 20 minutes in the case I was back up to 60%. I should also mention that these earbuds are extremely comfortable. Even after all that time in my ears, there was zero fatigue. The touch controls are the best that I have used to date. Extremely easy to use, customizable, and no errors so far using them. The Sennheiser Smart Control app has bunch of features you can turn on or off. It also has an option to manually EQ your earbuds, or personalize the sound to your liking. I highly recommend using this option, because to be honest, out of the box I was not too impressed with the sound quality, but after running the sound personalization feature, these earbuds came to life. I was also very happy to see that I could turn off the transparency option with phone calls. This is huge plus for me because I work in a very noisy environment(auto production plant). You also can set the audio resolution for those audiophiles out there, and there is also a low latency gaming mode. As for the active noise canceling, or ANC. The Momentum True Wireless 4 earbuds are the best I have used to date. I own several sets of ANC earbuds, and these have outperformed them all. As I mentioned earlier, I work in a very noisy environment, and after putting these in my ears, it dramatically reduces all the background noise. I'm very impressed with the ANC on them. The only complaint I have with the these earbuds is the microphones. They work fine in normal environments, but where I work, people struggle to hear me during phone calls. They say it sounds muffled and hard to hear. Overall I really enjoy using them everyday. Likes: 1.) Phenomenal sound after running sound personalization 2.) Exceptional ANC 3.) Excellent touch controls Dislikes: 1.) Poor mic quality in noisy environments

Gonna start with my only knock against these, I wish I could increase the transparency mode more for calls. That’s it. The Momentum 3 didn’t offer it at all so the transparency these offer is great, I’m just being greedy. Great fit, sound, controls, battery life, ANC, and their app is the best I’ve used for earbuds. These are my full utility headphones. I use them for the office, for out and about, on the plane, putting on some ambient music while doing things around the house, for some classical while reading, and occasionally for the gym. The ability to use these for the gym, and just for out and about, and not having to worry about these falling out of my head is huge. Sennheiser is one of the few brands that offers a nice set of ear fins, wings, or whatever you want to call them. I just hope they never stop including these on their higher end models because I need them for my ears. In the office these drown out a majority of the background noise and they block out enough on a plane that I can easily enjoy a movie. I generally read on a flight and these block out enough where I can still enjoy the light sound of some classical music. I haven’t had many complaints about people not being able to hear me on a call, overall happy with the call performance. When it comes to sound quality for listening to music or watching a movie are awesome. Across all genres these sound fantastic. Huge bonus is how well their app works, the connection manager is a great feature. Most of the time my headphones are connected to my phone and tablet and the connection manager makes it incredibly easy to switch to the TV if people in the house are going to bed and I’m staying up late. Much better than having to go through the settings and pairing options of other devices. With the app you can also customize the button settings on the headphones and the options let me have access to exactly what I need. If you can’t tell I love these, and these are paired up nicely with my favorite headphones for working out, the Sennheiser Momentum Sport.

I already own a Sennheiser Momentum 3 Wireless over ear headset so I was excited to try the next iteration of the momentum series with earbuds. I wear glasses for computer work which is where I use headphones most of the time so it can be tough combining an over the ear headset with glasses frames. Usually they put a lot of pressure on my temples which builds up quickly. I love the feel of the case, compared to some of my other earbud products. It has a textured layer over it giving a higher feeling of luxury. The other cases I have just feel like smooth plastic and although they work fine, I liked this new take on a case. They pair automatically out of the case, though you do have to plug the case in for a few seconds the first time to initialize the buds and power them on. After that, they power on every time you take them out of the case. For comfort, they mesh into the outer ear canal and have silicon fittings to create a seal. However, I found that after longer listening sessions this contact as minimal as it is, still creates a pressure point against the ear and can cause discomfort. I haven't experienced this issue with other earbuds that come more directly out of the ear and rely on inner canal pressure to stay seated. I found the noise cancelling and transparency features left a lot to be desired. I can still hear ample background noise (such as someone speaking or my kids playing in the next room) and couldn't honestly tell a real difference between the noise cancelling being on or off. The transparency feature just turns off any audio input to the earbuds so you can hear someone talking to you. Convenient at the single press of the left earbud, but almost unnecessary because the noise canceling is so ineffective. Finally, funnily enough, the sound quality is really good. I'm amazed at how much bass you can get out of an earbud today. For a Sennheiser product, these earbuds meet my expectations. I think you would probably get better sound clarity of the noise canceling was more immersive. I also noticed no input lag from my phone to the earbuds when streaming music.

Sennheiser beats Sony hands down with their sound quality. For contrast, I have owned Jaybirds Sport, Bowers and Wilkins Pi7 S2, Sony QuietComfort ll, Sony 700 and Sennheiser MOMENTUM 3 headphones, and Samsung Galaxy Buds Live. I have very small ear canals and have to have earbuds with just the right balance of fit and weight. Galaxy Buds do fit but tend to slide out after awhile. Their sound also just can't compete with Sennheiser or B&W. Other people can leave detailed reviews about touch controls and other tech stuff. I just know these sound great and fit comfortably for at least a couple hours. Anything I play through the Momentum 4's is crisp and detailed. Clear highs and mids and deep bass that I swear you can feel. ANC works very well for my daily use. It blocks traffic and neighborhood sounds so I can use them even when I do meditation outside. The case has a fabric texture outer layer that doesn't slip out of your hand. They're also a lot easier to get out of the case than the Bowers and Wilkins which have a deeper case and smaller surface to grab. I truly enjoy the MOMENTUM 4's the best of all the earbuds I own! I strongly recommend them if you can afford them!

Freaking awesome earbuds. Sennheiser really never ceases to amaze me. I haven't had a nice pair of headphones in a couple years now and have a couple pairs of sony earbuds and over ears that are great and I've always liked. The Sound quality is amazing. Exactly what you would not only expect from such an expensive pair of headphones, but from Sennheiser, they just have a different standard for their sound that I will always love. The App is the first one I've been willing to use for any accessories in a long time because of how awesome the sound profiles between neutral and podcasts are. They truly make a good difference in the listening experience when I am listening to music vs people talking and stuff. Also I havent needed it yet but I guarentee the find my headphones feature will help a lot. You can also customize the controls and a couple other cool nerdy audio things that are worth a look. Build quality of both the case and the buds themselves is very good. Only thing I wish it had was more of a "snap" when I put the buds in so I know they were grabbed well. Hasnt been an issue yet though. Truly the only "bad" thing I'm dealing with (its not that bad and i already knew Sennheiser headphones usually have this issue) is the battery life of the buds themselves. I work 10 hour shifts with 2, 10 minute breaks and a 30 minute break. I have had to charge then for an extra little while after coming back from lunch and on both breaks to get them to possibly last til I'm off. (They usually still are about to die when I get off) This is something I experienced with my last pair of wireless Sennheiser buds. But in my opinion it's the trade of for the better sound quality. Overall great headphones. If your debating on them I would highly recommend them.

When I unboxed the Wireless Earbuds, I noticed the premium feel they had. The case was sturdy and the presentation felt amazing. The case felt like you were getting quality. The Case also feels high quality. My headphones can stay in my pocket all day. The case is what makes a good pair of wireless earbuds. These deliver all around. Not too bulky much more firm and solid. The Earbuds by far were the most comfortable earbuds I've ever had. After a while, I'd forget I'd had them in. The Audio quality was crisp and clear. While listening to a podcast, you could hear the clarity and cleanness. While listening to music you could hear and be in the experience. When you have good audio it enhances the experience. It has an Adaptive Noise Cancellation Mode. With the window up and raining outside It blocks out a decent amount. Though, I've never been a fan of any Noise Cancellation this one was decent. You adjust this feature inside the app. The Transparency feature is one that I see as useful. Honestly, the best thing about the earbuds is that you don't need the app. Out of the box, the Earbuds sounded amazing. While listening to podcasts, videos, and audio. The interaction and functionality of the earbuds were flawless. Each press pressed and there were no problems with pause/playback. My only Negative would be the app. It seemed useless with not as much control. Yet, you can "Sign Up" for more control. I'll pass on that part. The Earbuds are a Home Run. Great comfort, Quality, Sound, and a Premium Price Tag.

The Case: When I first unboxed these, I was very impressed! Especially the case, it has this kind of class to it that I think other plastic earbuds lack! It feels nice and makes me feel like it’s an expensive piece of tech which I enjoyed! The case was compact, felt nice to hold, and fits in my pocket, and I felt confident that if I threw it in my backpack it wouldn’t break the hinge in there. Don’t ask me how I know about broken hinges from earbud cases in a backpack filled with stuff. But seriously I’m a huge fan of the case. The color, the feel, the weight, the snap when closing it, USB-C, and an easy to understand light! Fast charging, etc. BUT It’s not all sunshine and rainbows! The design of the inside of the case kind of leaves me wishing it was different! Putting the earbuds in and taking them out is hard for me and my big orge fingers! Just the way it’s designed makes it a challenge for me and makes me feel like I’m gonna drop something when I’m walking. I seriously have to STOP and get situated when pulling the earbuds out or back in. The other downer is the case doesn’t open far back enough! It’s like a straight 90* degree angle and now my knuckles knock against the back of the case further causing me to feel unstable when pulling the earbuds out! Not a huge deal, but I don’t like that. I wish the case opened up further and I wish there was a slot where I can put my finger in and lift the earbuds out. The App, Sound and Fit: I was disappointed with the sound at first, not gonna lie! I thought it sounded low quality, but the fit was a bit rough! Ear fatigue happened very quickly because of the design! But it wasn’t until I explored the App when all that changed! I’ll get to that later. When I first put it on, I lifted my ear so it would go in my ear and fit snug with a slight twist. It stays and it WON’T go anywhere for my ears! I can confidently say these are the best fitting earbuds for my ear out of any that I’ve tried and owned! I went on a run, did dishes, watched a show on my tablet while laying in bed, and they won’t come out… in fact they’re stuck in my ear and I’m now a Sennhesier man now! Kidding, but the way it stays put, it’s almost like it’s stuck in my ear! I love that it feels that secure in my ears! But because they’re so snug, I feel like it begins to get uncomfortable relatively quickly. Which is a bummer because it’s so great that they’re so secure! The sound was kind of flat sounding and felt hollow. Almost as if something was blocking the speaker. It’s hard to explain, but I was very surprised how not good it sounded to me. I figured it was an app thing and I needed to do something with the app. The app is awesome! No need to sign up for anything so awesome there! But noticed an Audio Resolution section. I switched it to Lossless which is the second highest setting and it changed everything. I don’t know what standard is, but once I changed it, it made a world of difference for me! Sound is crisp, dynamic and I love it! Easily the best sounding earbuds I’ve ever used! Explored the app some more and it has quite a bit of nice features like a pretty indepth EQ with some presets you can rename which is nice! I almost wish they started with Lossless and made Standard an opt in option for battery life. Maybe changed it to "Endurace" mode or something like that. Overall: I’m happy with these a lot. It has some quirks that aren’t deal breakers, but overall, solid sound, great app, aesthetically pleasing case, and secure fit make this a winner in my book.

The easiest way to explain these buds are by saying, they do everything well-exceptional. Sound quality and flexibility, exceptional ANC, very good Transparency, very good Microphone quality, good-very good App, exceptional Controls, excellent Battery life, very good. Quality fell and build, exceptional Workout buds, very good-excellent These are the overall best in ear buds I've ever owned. I have Bose Ultra, these are better. Technics AZ80, these are better. Denon PPro, it's close but these are better. Their size and style make them uncomfortable for my ears after about 30 minutes. If I could rate 4.5 or 4.8 I would rather those numbers, but these are not perfect for me. They are exceptional ear buds and have many amazing qualities. The thing that sold me on these buds, was how often I would see a person from Sennheiser commenting and asking for feedback on YouTube reviews of their buds. That and watching them make improvements to the suggestions, that stuff sold me. Great buds, I will buy more.
