Customer Ratings & Reviews

Disappointed by noice cancellation. I bought these because I work from home and have two dogs and live by a busy street, so I really needed something with good noise cancellation. I’m wearing them now with the custom noise cancellation set to the absolute highest, with the volume just above the halfway point on my phone and I can hear my air filter behind me and can hear my dog chewing on his bone. It’s driving me crazy that I spent so much money, to only have irritating and distracting noises while I work. I have found that the only time I can’t hear anything while wearing them is when I have loud music turned almost all of the way up. It doesn’t feel like the device is actually have noise canceling… I just have to blast music. which isn’t ideal given that I need to be able to focus for work and would prefer to listen to classical piano at which point there’s no shot of noise cancellation working. I do still give them three stars because they are more comfortable than other headphones that I’ve worn. I also feel like they have a more customizable fit because of the way that you can slide it to adjust. I also feel like the battery is great, I rarely find myself recharging them. I like the color-very neutral.

I am giving it a 3 because as amazing as this set is, all its features are amazing, the multi-device connectivity, cushioning force, noise cancellation, battery life, and anything else imaginable is all great. But the one thing that absolutely sucks is the audio amplitude. It is so low, and so many people on YouTube said that it's more than other premium headsets, but these are just not as loud as I'd expect a Sennheiser headset to be, so that takes away 2 stars for me. It almost seems like their hardware wasn't good enough for this one to maintain same level of audio quality at higher volume level. If you plug them in without turning them on, then the headphones show the real volume level and how it can go, but the quality with that is terrible.

Great headphones but has a crackling sound that shows up every now and then. Known issue but they still haven't really resolved it. Bonkers for this price range and quality. Otherwise, sound is top notch.

I have had a Momentum 2, a Momentum 3, and now a Momentum 4. This is the worst by far. I don't like the app. Everything should be integral to the headphones. The controls on the side are ridiculous. I hate their folding design (or really lack thereof). It doesn't come with a USB-C charge cable. Finally, the material is not as good. They don't feel as good. Also, I have really oily skin and the headset just shines after being used. The past iterations were far superior. They also pop with noise from connection problems. The past iterations were far superior. If gaming headsets were lighter, that is what I would do, if you can find an alternative, do so, especially for the price.

The sound quality is good. The comfort level is average. The connection is not very flexible. Overall it is not bad.

Cover on the headphones started to separate from the headset. The ear cushions started to become discolored, they look awful.

I really love these headphones, noise canceling ,clarity, and battery life are stand outs if these headphones. The app is standard headphones are lightweight and comfortable. I wish they folded more and had a little more head pressure. They were great for listening sessions but could not run hard in them without them falling off because how they rested over ears lightly. A hard walk and even light jog was fine. If you like good anc, and good sound. Worth the try

I’m returning because they’re too finicky. They fold in a way that’s super easy to get in the case, but the don’t also fold in so I can’t get them in my pocket if jacket. The controls are too touchy. Sometimes thy work and sometimes don’t. The auto recognition for laying down headphones to pause is too sensitive. I can turn or just look down in a drawer and they pause, very annoying. The sound is amazing however. I did a trial of the higher priced brands with Sony and Bose. The bass the momentum 4 gives is so smooth and low. The noise cancellation beats all the competitors. This would be a great product if it would just be before touch buttons.

I bought these for dual purpose - Teams Meetings at work, and for music. The good... The sound is great, nice bass, crisp high and clear mids. The sound cancelling is fantasic. Very comfortable, I can wear them for an 8 hour shift with no problems...no pressure on the top of my head or ears getting all sweaty. Battery life if great - I know I can go the whole work week on one charge. Now the bad - and I think it's mainly due to the software. The touch controls - these can stop responding, I then need to essentilly reboot them to work again. The touch controls can get a bit flaky, for instance double touching them should turn noise cancelling on/off but they can get into a state where it tell me "mute off" or "must on" but in reality, it kills the audio so I can't hear anything. Reboot to correct. Connection will sometimes drop...maybe 1 or 2 times in a work day. Usually in this case the "press and hold" option on the touch pad will reconnect. This happens with work laptop and my cell phone so that leads me to think this is related to the head phones. The touch pad might be impacted by hair, or clothing...but I have no hair that would impact that and I usually wear colarless shirts at work so that is not an issue. Maybe it's caused by random head movements? Maybe someone can tell me if I can a defected set? If so, I'd appreciate it...thanks

Amazing hardware as always from Sennheiser like always. Comfortable fit and good build quality. Major problems with software and features. I got these to upgrade from the PXC-IIs that were starting to drop my connection after 4 years of use, while, the PXC-IIs were not perfect at connecting with more than one device at a time, they preformed far better than the M4s. I will be listening to music or on a call and if battery saving auto detection mode are on, the M4s would randomly disconnect, even with active audio coming out of the headsets. This ought to be a simple firmware fix, but reading online it seems this has been an ongoing problem since launch. I really wanted to love them because my PXC-II were amazing. Another pet peeve is that you can’t turn off ANC at all, you can only toggle transparency mode across a slider. All in all the M4s are great for reproducing sound and ANC, and the battery life is amazing but all the poorly implemented “features” make this model a miss for me. Might be returning them.

I read alot of reviews about how good these sounded. I was broken between this the momentum 4 and the skull crusher anc 2. So i bought all three of them to make my decision. Highly dissapointed with the bose qc ultra. Im using iphone 15 pro max and the volume for these are atrocious. They are to low. I like loud music so that was the first turn off. Anc is good about the same a little bit better compared to the momentum 4. Crushers anc 2 anc is meh compared to both. Definitely not even close. Bose has the best ambient sound with sennheiser second than crushers. The base on the bose im sorry is complete trash. Senheisser sounded better than the bose in all aspects. Obviously the base is way better on the crushers. But what overall killed it for me was the sound. If you like vocals sure knock yourself out. Best build easily are sennheisers than bose than crushers. If you want loud like me stay away from these bose qc U. I dont know how they sound with android. These are definitely going back. Now for the sennheisers the loudness was good I definitely had to tweak with the EQ. But the base when you max it tends to pop alot. A high pitch popping sound. Maybe i had a defective one i dont know. Either way these will go back. Im staying with the crusher anc 2 which have better base when adjusted and is louder.

I’m writing this review about 6 months later and these headphones sound amazing. Best headphones i’ve owned. The noise cancellation isn’t the strongest but when you’re playing movies or music you’re not going to hear anything. 10/10 on sound, it’s the complete opposite for connectivity. There has been multiple occasions and more frequently where i’m listening to music or watching a movie and the headphones just turn off, or disconnect. Then i have to turn the headphones on again and it’ll reconnect and another 20-30 minutes later same thing. Battery fully charged, software up to date, etc. I can be sitting complete still and it just disconnects. Not sure the issue with that but i had to take off 2 i was even thinking 3 stars just for that. It’s very annoying and frustrating. It’s also annoying how when you pick up the headphones after turning them off they turn on and connect to my phone. I wish the on/off button was the ONLY way to turn them on and off and there’s been multiple times i’ve simply tried to move the headphones away from me on my bed watching a video and they connect to the headphones. It’s very annoying as well. I had no issues at first but after about 3 months this issue with it disconnecting started happening. Also it is very annoying trying to simply turn them on, you have to hold for 5 seconds and sometimes there’s no reaction from the headphones and they don’t turn on. Sound is amazing but it’s lacking in other areas. I’ve considered returning but i’m way past that now. May just end up getting airpod maxes but that price is ridiculous for the sound quality you’ll get out of these headphones maybe even better. Overall 2.5-3/5. I’d recommend it still just purely for the sound. Everything else needs to be addressed in future releases.

I bought these headphones 2 years ago during Black Friday and decided to finally write a reciew about them. Hesitant on exactly how many stars I should rate it, but ultimately decided on a middle 3 stars. These headphones are good, they sound great straight out of the box and you can use the app to tweak the EQ if you want (although recently I feel like the EQ settings aren’t really effecting the sound at all). But then comes the issues I’ve had with this headphone for the last two years. While Sennheisser makes incredible sounding products, the software and user experience on these are simply terrible and frustrating! I’ve had to turn off and on the headphones numerous times because of connectivity issues. My biggest gripe comes with the touch controls bring unresponsive sometimes, which causes the ANC and Transparent mode to not work (turning the headphones off and on fixes the problem sometimes, but the odds aren’t that great). Recently, I’ve had issues with the on-head detection too. Taking off the headphones doesn’t pause the music (and guess what, I can’t pause it with the touch controls because, well it’s unresponsive again). Toggling the on-head detection setting in the app doesn’t fix that problem. Overall, these headphones sound great, the battery life is incredible (I rarely charge these). But the overall user experience is just horrible, borderline unusable sometimes. If you’re looking for headphones just get the Sony WH1000XM4s or XM5s.

The headphones are beautiful and sleek. They feel really nice and are comfortable. They have a great battery life for the most part. I didn’t like that they had a somewhat strong chemical smell and a Prop 65 warning label. I was also disappointed that the sound quality wasn’t as great as everyone said it was. I was expecting way more from these headphones in terms of sound quality. The sound quality is good but not what I was expecting. The noise cancellation was pretty great at times I did feel a slight pressure, but overall very happy with the features and noise cancellation.

Let start by saying the sound is excellent, so for their primary purpose these fit the bill. What drops this to 3 stars for me are all the features that take away from the experience instead of making these more pleasant to use. Pros: excellent sound quality, battery life, good app support, comfortable, included case and cables Cons: sub-par noise cancelation, auto off, auto pause, touch controls The pros are pretty self-explanatory, these headphones are very good as an audio sound device however the features are poorly executed. The auto off takes forever to activate and it doesn't recognize putting them in the case so you need to manually disconnect (making you also need to manually reconnect). The auto pause when you take them off would be a great feature but it only works with the right ear cup and is overly sensitive on top of it. I couldn't count the times I scratched my ear or slightly adjusted the fit and had what I was listening to pause. The controls are all capacitive and on the right ear cup only, except for the disconnect/power button, and are pretty annoying to use in my opinion. I'd rather have a slider or buttons on the side of the cup instead of the whole side of the cup being a touch surface (which can and does get hit when using these while laying down). Now while these cons may sound minor, the sheer frequency with which these annoyances occur makes these headphones frustrating to use at times. A fan could excuse them as "quircks" but for how expensive these headphones are this many "quirks" should not exist. If I could go back in time, I would shell out the extra money for the Sony headphones. Do I regret this purchase? Not fully, they are good headphones overall with high fidelity and great battery life, but they wouldn't be my first recommendation. They are noticeably better soundwise than my old skullcandy headphones, but at over twice the price they had better be.

Writing this review after using it for over 6 months. Pros sound quality is excellent and battery life is what they claim to be. I use this headphone everyday for almost 8-9 hours and still it functions without charging them. Very comfortable to wear for hours. Cons Lots of connectivity issues. Auto off feature seems to disconnect with the device and I always have to start over every time I take them off which is very annoying.

I am long time fan of Sennheiser over ear headphones, so I was excited to see these hit the shelves. The build quality is great, the ear pads could not be more comfortable, and they hug my head nicely. Sound is great, it is Sennheiser after all, an old reliable brand in the headphone market; and the noice-cancellation was good for an over-the-ear style, although it can not compare to newer in-ear bud noice-cancellation options. Battery life is incredible. So why the low rating? They are extremely annoying to use! The touch interface is a TERRIBLE design, made worse by how it has been implemented on this device. When I lead my head from side to side any contact with shoulder will trigger the play/pause controls, even through my shirt! Readjusting the headphones, which happens often with big over the ear sets like these, triggers the auto-sense play/pause over and over while listening, and sometimes other controls due to the touch interface triggering. I attempted to see if I could disable or configure some of these settings to be less annoying, however no such settings exist. Aside from that I did experience a small issue with pairing via the app, as others have noted, although restarting the app fixed the problem. My bar is so low for device specific apps that I am happy if they work at all, which this app did, I just wish it offered more control over the touch sensitivity, gestures, and auto-sensing activity.

[Employee of bestbuy] First of all. Out of the box the headphones are beautiful. They look good, they feel good as far build wuality goes. More metal that plastic unlike a lot of ither headphones. My main issue with these headphones is the app, and touch controls. The all is pretty basic, althought easy to navigate. I think the sound personalization option is very lame and limited. It doesnt let you use it and listen to your own music like sonys does, instead you have to listen to some crappy generic sounding pre made song that the app plays. Also you can’t listen to high rez and use sound personalization. Youre forced to stick with a five band eq. Noise cancelation is pretty sub par but they do handle wind sound better than abything else youll find at this price point. Batterly life is off the charts though. I used them for two weeks and didnt have to charge them once. The other thing is these headphones touch controls only worked half the time, and sometimes it didnt even realize the headphones were in my head. So that was pretty lame. Another thing is the headband has like a mm of foam before you just have plastic resting on your head, and the clamp force of these guys is irritatingly strong. Over all not super comfortable.

This is the first time I’ve had the opportunity to try out Sennheiser headphones, though I’ve definitely heard of the brand before as a staple of quality for the category they fill. Overall, I have been happy with the audio quality, so if audio quality is your primary reason for looking at this headphones, I can comfortably say you won’t be disappointed. However one of the reasons I was excited for these headphones was the active noise cancellation (ANC). I work both in an office and at times from home, so I need to drown out noise from other people or children, and these headphones proved to be insufficient and less efficient than another pair of ANC headphones I have. The app these headphones pair with walk you through how to use all true features, like pinching to adjust the degrees of ANC, which was a neat feature, but even at its highest degree of ANC, I could still hear noises from other people or kids when wearing them at home. For contrast, I was wearing a different pair of ANC headphones at work when a fire alarm went off, and I didn’t know the fire alarm was blaring until I saw other people leaving the building. I used these headphones also while gaming and talking to a friend over in-game voice chat, and they mentioned my audio from my mic came through very clearly, so I have no concerns about the built-in mic. Ultimately, because I feel ANC is such a hugely integral part of a product like this, and this fell short of my expectations on that front, it’s not a product I would recommend. I still plan to use it for voice chatting and music, but I’ll need to use different headphones when I’m trying to concentrate while working.

These headphones are great with the ANC mode; however, over time they have lacked in quality. The right earbud especially creates wind/crackling noise and I cannot seem to turn it off when it occurs (which is often.) I do love the battery life- the best perk of these by far! The hand touch controls have also gone wonky after 6 months of use. Disappointing. Will be submitting for a warranty claim, and it seems as though many other people have run into this same issue. Hopefully there’s a fix to this,
