Customer Ratings & Reviews

I have one complaint that I’ll get out of the way. The case is big, maybe not gigantic and it may not bug you but it is significantly bigger than other earbuds, now what you get out of that is may be a trade off you willing for, I certainly am but if that is a major requirement before sound quality then just know that. Noise cancellation: Hands down the best I’ve used (First headset of this brand). I’m used to a very faint vibration that can bug me after awhile from noise cancellation. These, it was gone, not mostly gone, but just gone, it’s the first time I haven’t noticed it at all, I’ve used others that weren’t at a level that bugged me, but these are on a completely different level. So if you like me and can hear/feel noise cancellation, give these a go as they have become my favorite. Adaptive Noise: Depending on what you find important this isn’t the best, I turned it up to high in the app and it is still better, but it seems to want to prioritize music first, which normally I agree with but my five year old doesn’t come through that well and I end up pulling the headphone out, which may be better anyway so that he knows I’m giving him my attention, but that is a different story. As for everything else, it brings through voices quite well normally, but they aren’t super amplified like other brands, its more of a combination of noise cancelling and ambience accentuation. It will muffle something like a fan background noise, but background music comes through. I like it but it could use some improvement is the best way I can put it. But it is in the top two for adaptive noise for me. There are also three settings; off, on and anti-wind; all that do exactly what the setting name implies. Fit: There are several buds for different sized ears but the ones out of the box worked great for me and lock I nice and tight. Bluetooth Connectivity It doesn’t lose connection anywhere in my house (I have a 2700 two story house so not giant but not small). I can go out to the car, and it is still connected solidly. If my phone is in my back pocket, it still works. One time one of the buds didn’t connect, however just touching it made it turn on, it was at this point I realized it is extremely useful that both tell you they are on and connected individually. Also, they can be connected to two devices and switch between the two, however they don’t switch if one is active back to the other one. Which is exactly how it should be. So, no interrupted meetings for a phone notification if you have the connected to your phone and computer. Also, it supports two devices. Charging: The battery lasts forever it seems like. Sometime a big case doesn’t mean a big battery, in this case it does. It also supports wireless charging and worked on two different generic wireless chargers I have at my house. The earbuds themselves last for hours, longer than I can keep them in. Sound: There doesn’t seem to be much different in earbuds these days from low end to high end, you end up just paying for the name in the worst case or maybe noise cancellation, integration, or other features in the best case. If you are into lossless music these should be at the top of your list. It does make Spotify sound better but there is only so much you can work with there. Something like Tidal, amazon music, or Apple music that offers lossless or UltraHD or whatever they call it really allows these to shine I am absolutely in love the sound quality for size with these. One thing to keep in mind is your phone needs to support lossless music which, I believe apt x adaptive is the recognized lossless codec. The App: Usually the app isn’t anything special, however the amount of control it gives you over everything is amazing. The equalizer can be customized, there is a bass boost, a podcast setting, and a bunch of other presets that are pretty standard for good equalizer apps/settings. The podcast one is not standard from what I’ve seen in the past. It brings the voices out and makes them loud and clear, it makes up for sometimes not perfect recording settings that can be on YouTube or Spotify. Touch controls can be customized as well as auto pause for transparency and such. There is even a sound zones setting, I set the noise control to transparent when I get to work but I couldn’t change the equalizer to podcast sadly as that setting is helpful in meetings. The settings tab shows firmware updates, but even better there is an audio resolution as well it shows the Codec. There is a battery eco setting that I don’t have on as audio quality is more important to me, but I did turn on battery protection mode which prevents charging to 100% and slows down charging, I still don’t have any issue with running out of power after making these changes. Overall: For truly wireless ear buds deliver an amazing experience in audio. If you are going to keep the bit rate at low, data saver one, and so one that degrades the audio experience, these may not deliver the value that they could. If you are interested in utilizing these to their full potential, I believe they provide an awesome value.

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.

These sound good out the box. Doing custom spund test makes them amazing. Loved them for 3 weeks. Then my mics stopped working well. People on other emd of calls complained of muffles low voice. I would put buds in case and then reconne t and I would sound good for less than a minute then right back to muffled. I tried adjusting transparency and anc. Nothing fixed this.Returned for refund.

I love the clarity of these!! Anc is really good. They feel good in my ears amd they have really good battery life.

Wasn't sure because of the price, but completely satisfied. And even with how small the wings are, they don't move at all once in. That's one of my biggest complaints with most earbuds

Would get a 5 star if I didn’t have issues connecting to my phone.

I hate to give lover than 3 stars every product has some quality that is reason we buy that product. Problem those garbage headphones has in my case if you don't use them for 3-4 months they don't lose capabilities to charge, one You Tube member explains very well. People at Sennheiser know that flow but they don't care about people and customers, as Globalization rules they will always find million innocent people ready to spend hard earned money on garbage.
