Customer Ratings & Reviews

Returned, sound is great but microphone could be much better. Nobody heard me while talking in a windy area.

For my review of the Sennheiser Momentum True Wireless 4 Earbuds, I want to simply state right away that these are some of the best sounding earbuds I have ever listened to. Like most earbuds, it does require some customization using an app on your smartphone. But even straight out of the box, I liked the sound immediately and once I changed some settings, I can’t get over how great they sound. Once the app “Sennheiser Smart Control” was installed on my iPhone, I was immediately alerted to a firmware upgrade. From there I was treated to all kinds of customizable features, including noise cancellation, transparency level, touch control, a fit test, sound zones, and finally, My Sound. My Sound gives you the option to use either an editable standard 5-band equalizer or something called “Sound Personalization”. After some experimentation, I chose to use Sound Personalization. Apparently, this might be a feature that came with a recent update as I was unable to find much documentation about it. Basically, you move a cursor around a 2-dimensional grid diagram until you find a sound stage that appeals to you and save. I found placing the dot in the lower right quadrant worked best for my ears. Once set up with the Smart Control app, the sound coming from these earbuds is amazing! The bass and drums are tight and punchy but not distorted or boomy, and the mid/high frequencies are crisp and clear but not harsh. Hard to believe such sounds are possible from something so small. It makes me anxious to listen to my favorite songs as it brings them all to new life. I enjoy a wide range of music from Aerosmith to ZZ Top and with the latest lossless Bluetooth quality, I am blown away by how good everything sounds. I am not technically an audiophile, but I am an avid music listener and I really like what I hear from these Sennheiser earbuds. The earphones themselves are beautifully designed and come in an elegant fabric-covered case which is rechargeable using either a provided USB-C cable or you can use wireless charging. The earbuds come with several ear tips to fit every ear. I found the ones it came with fit perfectly. There are LED lights on each earbud that provide status information as well. I found an additional use as I dropped an earbud on the carpet in the dark and was able to locate it immediately because of the LED light. I find the fit to be very comfortable and have no complaints after wearing the earbuds for several hours. Touch controls are simple and easy to learn by reading the manual once, but controls can be customized should you not like how they are configured. I am not one to make use of all the available features like low latency audio, noise cancellation and Auracast, but these earbuds have all the latest technology and more. I’ll leave that for others to discuss, I need to get back to listening to some Emerson, Lake and Palmer!

Doesn't work just got it tried them on and left earbud is dead. Like first try on theyre dead. Bought these hope reviews ive seen were wrong nope. They fit nice but cant tell you how they sound.

The case design feels very premium. The fabric look is unique and durable. Charing is over usb type c, or wireless. I do with the case were a big slimmer to make it easier to put in pockets. The included wing tips help to keep the earbuds in place, and are very comfortable. Everybody has different ears, and there are several tips and wings included in the package. The adjustments in the app allow you to create a custom sound just for you, or use some prebuilt selections in the app. Music and podcasts sound very natural with no distortion. They make all different types of music sound great. The active noise cancellation is great with two modes, wind or adaptive. The adaptive cancellation worked really well in a room with a loud fan. The transparency mode works well and can be adjusted in the app. The microphone works great for phone and zoom calls. In a semi-loud room or outside with wind they performed well and I could be heard by others without any problems. You can connect to multiple devices at the same time, which has worked will when using a laptop and phone. The earbuds easily switched between devices as needed. The earbuds support AuraCast and should help to future proof these earbuds. This will be coming in a firmware update. Battery life is 7.5 hours, 30 hours of charge in the case. IP54 water and dust resistance are nice to have. I have used Sennheiser over ear head phones for years, and these wireless earbuds are a great addition. The combination of fit, design, sound and microphone quality, noise cancellation, and transparency mode make these the perfect daily use ear buds. There is nothing missing here, making them the best earbuds I have used to date.

Great when they worked stopped working about 6 months after purchasing

After 8 months the right earbud only crackles or works if I tap it. Then it stops again. For this price it should have lasted YEARS not months

Right out of the bix, both buds are defective. Charged it right away, buds do not “activate” or turn on. Tried troubleshooting and researching for an extended amount of time. Found similiar issues but generally limited to one bud. They basiclaly have no customer serice to get ahold of either. Definitelt highly dissapointes.

One of the buds stopped working after two weeks and I didn’t get the warranty

Returned it. Bass was nonexistent despite multiple EQ attempts and trying both Apple Music and Tidal

The headphones were a little static key and they were not the sound quality that was promised for the price

I was not a fan of them. The audio sound stage was small

These make Airpods look like cheap knockoffs. The case is a nice hard plastic case wrapped in a nice premium feeling textured fabric. There is a USB-C charging port on the front, with a status LED next to it. Honestly I kind of wish the USB port was on the back, but really at the end of the day it's kind of inconsequential. The case is magnetically held closed, and feels nice and secure. When it's open, it is held open and doesn't get in the way when trying to take the earbuds in or out. You put them in your ear and rotate back slightly to secure them in place. Earbuds are something I've almost always found to be uncomfortable, especially for extended periods of wear. These, while on the more comfortable end of the spectrum, I still found to be uncomfortable after wearing for an hour or two, but that's not terribly surprising for me. I did try the different sized earcups and the ones that came fit best. It also comes with different sized "fins", which are silicon rings around the earbuds that help secure the buds in your ear. You really need to install the Sennheiser smart connect app to get the most out of these. In the app you can control the nose cancellation (On, anti-wind, off), "transparency" level, customize touch controls, and a fit test (to ensure the earbuds are well fit in your ear). You can adjust the EQ in the app, including turning on Bass Boost (which I recommend). I also recommend going into the settings, and setting the audio resolution to "high resolution" or "Lossless". it defaults to standard, which may help bluetooth range, stability and the battery life of the earbuds, but if you're listening to high quality audio you'll notice the difference. The app also has other battery settings to prolong playtime by disabling power-hungry aptX codec, but also to protect the battery health by slowing down charging and limiting the maximum charge. Unless you use these all day everyday, turning on battery protection mode is probably a good idea. Audio quality and noise cancellation are great. Still not as good as over-ear headphones, but among the best I've ever used. I've been using them for a couple hours a day for the last 2-3 days, and the case battery is still at 80%, so I'm really not concerned about battery life at all. Really it's hard to find any fault with these, except maybe comfort as I mentioned before.

The Momentum True Wireless 4 are a nice upgrade from the version 3. The sound output seems about on par but the improvement comes in the noise cancelling. While using them at work most of the jibber jabber in the background became whispers and the drone of some of the machinery was almost non-existent. It handles steady sounds better than varying sounds. The audio quality is top notch, which I'd have expected from Sennheiser. The only problem creeps up in bass heavy tracks with long base lines. A Tribe Called Quests "Vibes and Stuff" is what I always use to test how muddy the sound can be at max volume. Not many headphones pass the test and the Momentums are one that didn't. Now, I never use maximum volume so it's actually a non-issue, but still a test I like to run. Tweaking the EQ and the bass was manageable at max with clean mids and highs coming through. One compliment to Sennheiser is that the don't force you to make an account to access the settings of you buds so many companies seem to make you do. You have the option to sign up and it's only required if you want to run the test to have the app personalize your sound based on your hearing and ear shape. I usually tweak things myself and never touch the apps again so not having to open accounts is a huge plus. The buds fit extremely secure and tight. The default tips sealed my ears so well there's a bit of suction when removing. The downside is that my left ear starts hurting after a few hours. It's no fault of the Momentum 4's, but more to do with the shape of my left ear canal. Most headphones that use your outer ear to apply pressure to keep them secure puts just a bit too much pressure for my left canal. My right never has any issues. So this isn't an Momentum issue, but my own body issue. Just mentioning it if there are others with issues with buds that apply a little pressure for fit. Right now it's a toss up on which iem's I own that are my favorite. The Momentum has better noise cancelling but my other pair doesn't cause any discomfort. The Momentum would leave me less worried about them falling out where my other set has come out when I get sweaty a couple times. So I'm torn on which will become my daily driver. Kinda leaning towards the Momentums because of the audio quality and the noise cancelling.

Case although nicely textured from a traditional buds case feels easily damagable from stains or drops as it is cloth. Headphones after updating software still dropped connection multiple times. Although a solid earbud choice, for the amount it would not best out other options by my recommendation.

LOVED the earbuds. Everything is great on them, ANC, quality of sound, fit, but people said I sounded like I was in a barrell. Shame, I really liked these.

I really wanted to like the Sennheiser Momentum True Wireless 4 more than I did. My score is coming from an iPhone 15 Pro Max user who is heavily outfitted with Apple products. My views are as impartial as I can be given what I could test these with. Pros: - Excellent, premium build quality - Outstanding battery life - Excellent noise cancelling (if you can get a proper seal) - Slightly above average sound quality (on iOS, probably better on Android) - Awesome for Android users Cons: - Largest earpiece was still too small for my left ear so I couldn't get a proper seal - Audio quality wasn't as good as my AirPods Pro 2 (which is probably Apple playing favorites) - Case is fairly large by comparison - Adaptive ANC was OK at best. Control of transparency and ANC was convoluted, turning on one turns off the other yet there is some overlap in capability. - No reason to select these over AirPods Pro if you are an Apple user. - No Spatial Audio support on iOS - Fit feels solid, but I did have issues with one not staying seated in my right ear. Overall, these are a tough recommend for iPhone users. Frankly, the AirPods Pro 2 can do better for less money. I think if you are an Android user these are an obvious winner.

Having tried these Sennheiser for the last week, these are high quality ear buds. Set up was simple and I was up and running in about 15 minutes total. They are solid and have some actual weight to them. Nothing negative, it is simply to say they feel well constructed and have a high end quality feel. Once I set up my own sound preferences via the app, I put these throught its paces. The sound is outstanding and the bass, mid range and treble are crisp and totally enguf you in the sounds. The touch sensitivity is quick and responsive. There was no unnecessary drag to anything. Sound for phone calls is as equally impressive, and with noise cancellation it has just the right balance. The only reason I did not rate these 5 stars is because I feel the true noise cancellation could be better improved. I could still hear pretty much everything on going on around me. I have tried several other brands and while these just seem to miss the mark, I am hoping a software update will easily correct this situation. Other than that, these are absolute winners. I would definitely recommend these regardless.

So I am on this odyssey for the perfect headphones and after adding Apple's AirPod Pro 2, and Bose's QC Ultra earbuds to my arsenal, it was clear that the functionality of the Airpods was unmatched (with iOS devices) while the QC Ultra sounded better at the expense of missing comfort features. So, the Sennheiser True Wireless Momentum 4 (TWM4) became more interesting. The unwieldy name aside, the "true wireless" is essentially reserved to earbuds and Momentum 4 continues a respectable line by audio veteran Sennheiser. At first contact, the case for the TWM4 is taller than the QC Ultra while still feeling smaller. It's of course bigger in almost all aspects than the AirPod Pro 2. Wireless charging (of the case) is fortunately included, an odd omission from the QC Ultra, even if the charge level is not reported to the Smartphone unlike the AirPods. The App is probably one of the more minimalistic of any of them and sub-sequentially comfort features like conversation awareness or spatial audio are absent. At least the latter is greatly compensated by an excellent sound profile. Custom profiles are possible but neither intuitive nor necessary. In my opinion, the TWM4 are the best sounding earbuds in this mix (only bested by a recent glance at the Denon Perl Pro). I think neither are sounding bad or mediocre. Yet, the punchy base and crystal clear separation is coming out on top, even compared to the Bose QC Ultra. This is also based on personal preference, but to that degree it's my verdict. So, the Sennheiser True Wireless Momentum 4 may not get the buzz but are worthy competitors for the beast earbuds in this price range (under $400). They're not perfect, but the wireless charging case (yes it's a big deal to me) and the punchy sound profile (my main reason) make it an excellent choice.

Great sound, connection, and ANC all in good quality built device. The personalization software has no peer. It is amazing how they can get so much sound out of a single driver.

Excellent sound quality after adjusting it in the app. Great battery life.
