Customer Ratings & Reviews

These are quite the Wireless headphones. I’ve not had the pleasure of using the Momentum line of Sennheiser’s headphones but have several different pairs of their other models. In terms of audio quality, these remind me a bit of the old school PX-100’s that they made back in the early 00’s which you can no longer buy. They got some great punchy bass which is something I always look for in headphones. I do quite like these. They’re marketed towards a certain line of users. I won’t mention those competitors, but I imagine you can deduce those brands. I do have a set of one these competitor headphones, so I do have some of a benchmark to compare to. For audio quality, they’re somewhat similar. They’ve got punchy bass and good mids and highs. I tested them with various kinds of music, and they handled it all well. They can get quite loud and are pretty much free of distortion with even the most bass heavy of tracks, though that will be determined with length of use. For battery life, I can’t speak to the claimed 60 hours peak playback time, I did listen to them for a few hours and the battery life barely budged. The Noise cancelling is ok. It's not near as good as some other brand's. They do an effective job at blocking out a good deal of outside sound, but again, there are better options for a similar price. They do fit well though. They are not near as clamped as my HD6XX Sennheiser’s. In time I imagine they will loosen up a little bit for me noggin as I’ve got a good-sized melon. They never did grow uncomfortable though which is always a plus. As for the app, I’ve used a couple different wireless Sennheiser products, and the app has always been the weak point. This seems to still hold true. One of the things I immediately noticed was that the EQ doesn’t work at all. I tried multiple different preset’s, my own settings, restarting the app, power cycling the headphones, but nothing changed. It’s possible that the app may need to be updated to support the Momentum 4’s, there was nothing at the time. It did see the Momentum 4’s however. As for the value, I don’t know if I’d say these are worth $350, I’d say they should be positioned lower, maybe around $270 or so. They’re in a price bracket with some stiff competition.

For me, these headphones are replacing the Sony WH-1000XM4. The Momentum 4 are more comfortable to wear, in that they seem to retain less heat. The Sony’s seem to get hot on my ears after wearing for long periods, and I have not experiences this with the Momentum 4. The setup process was maybe the easiest I’ve ever had. Download the Sennheiser Connect app, it automatically found the Momentum 4 and paired. Ready to go in just a few seconds. For the sound, out of the box the Momentum 4 was too bass heavy. This is easy to correct by using the app to adjust the equalizer settings, or set up a new profile. In comparison to the Sony WH-1000XM4, there are two areas when the Momentum 4 excels. The battery life is amazing. Fully charged, and I’ve been wearing them for several hours, the battery has barely gone done. This gives me confidence that they will reach the claimed 60 hours. The only area where I prefer the Momentum is the responsiveness - in pairing and touch controls. When you pick the Momentum up, it automatically turns on an starts pairing. In most cases, the headphones are fully paired by the time I can place them on my head. The Sony will take several seconds, making me check that it really did connect. The Momentum touch controls are easy to use and almost instantaneous. One tap to pause/resume, two taps to toggle transparency mode, swipe up and down for volume, forward and back top skip, reverse. I’ve not had any missed taps or swipes, and the action is super fast. This has made me comfortable using the transparency mode - on the Sony I couldn’t always trigger the transparency mode and it also sounded a bit odd. The Momentum’s a very natural, not overpowering your ears with the audio the mics picks up. I can tell that the noise cancelling is not as good as the Sony, which is expected as the Sony seems to be best in class. However, in my environment this doesn’t get in the way. The Momentum’s also have a really nice understated design, and the carrying case is nice to provide protection and manage cables. Overall, the great battery life and sound quality make these a great pair of headphones.

These headphones are amazingly Fantastic with sound quality, build, and Noise cancelation. I will be honest these rival sony's xm5's which have no doubt the BEST noise canceling hands down. For the momentum 4, the noise canceling isnt as good when compared to the sony xm5 but the sound quality is 2x better. If i could give into perspective how i see it, SONY xm5 - noise canceling 5/5 -Sound quality - 3.9/5 -Battery life - 3.5/5 - comfort - 5/5 -price - $399 Sennhieser momentum 4 - noise canceling 4/5 - Sound quality - 5/5 - battery life - 5/5 - comfort 5/5 -price - $349

I had heard often that Sennheiser headphones were famous for their superior bass reproduction. Trying on these new Momentum 4 headphones let me know immediately what everyone was talking about. It was fascinating listening to recordings I’ve heard a thousand times and yet hearing something totally new with these phones. First, everything about these headphones says “premium.” When you first put them on you can feel how the softness caresses your head without any unnatural pressure. You can adjust them effortlessly to fit. Downloading the Sennheiser app is a must. When first listening without the app, the headphones sounded ‘flat’ and I was a little worried. The app took care of the problem. You can simply adjust the equalizer yourself, or the app actually coaches you while you listen to a favorite tune, it gives you a few different choices with different frequencies in your song, and then gives you a final suggestion for your ultimate sound. It’s kind of like when you get fitted for eyeglasses and the optometrist gives you “A” or “B” choices repeatedly until your prescription is just right. Another ‘plus’ of the Momentum 4 is the incredible battery life. Sennheiser says it’s 60 hours at normal volume and noise cancellation. That’s twice as long as any other headphones I’ve seen. The headphones also feature a two year warranty. Since these ARE noise cancelling headphones, that’s an important feature to discuss. The cancellation is very good, maybe not quite as powerful as the premium Sony phones, but pretty close. You’d have to really do an “A” “B” test back and forth between them to really notice the difference. The headphones shined when using them for phone calls. The callers sounded crystal clear to me, and the people I called while using them could not tell whether I was talking into my phone directly, or just using the headphones on the call. I don’t know what more you can ask for. You do need to go through a ‘learning curve’ to learn to control the headphone’s features. There is only one physical switch, which turns the phone on and off and is used for pairing (although my headphones paired automatically with no assist from me,) Everything else is done by using the touchpad on the right earpiece, starting and stopping your music, skipping ahead or back, answering the phone and more is done with various finger movements along the pad. The case also says, “premium.” It has a heavy-duty zipper, and the headphones drop right in. It has elastic bands to hold the USB cord, an audio cable if you’re not going to be using Bluetooth, and even an old-fashioned ‘airplane adapter’ if they even use those anymore. Bottom line, if you are really looking for state of the art over-the-ear headphones, and from one of the most famous names in audio equipment for over 75 years, you will not go wrong with the Momentum 4’s.

Unfortunately my headphone power button was not operational so I was not able to power on and it was necessary to return the item. I researched on Reddit and it appears to be a very known issue with this model unfortunately. To be fair, I picked up a second pair and they powered in but after having read about all the issues I returned for a Sony m4 model.

bad sound quality. I am not sure if I am already used to open backs. But the sound quality is really bad.

touch pad very glitchy. they turn off unexpectedly. for the price not worth it. i’ve used them for 30 days and would return if i could.

Absolutely the worst. Do not buy. Ours stopped working shortly after a year. They sent a replacement which they said was new. It was refurbished and the one side rattles. Absolute waste of money. Do not buy.

Incomplete atm, I have owned this device for 21 days, and it stopped working. Bad best buy return policy means I have to wait who know how long before I get warranty service. yay

Was a good pair of headphones for 2 months, now it keeps trying to pair to other devices when it is already paired. I turn it off and it turns back on by itself and goes back trying to pair. I regret this purchase!

I really love these headphones. They are the most comfortable available on the market in my opinion. They sound great and feel is second to none. The range is great for anything any home user would use or want. They are exceptionally great for Android or iOS devices. They don't tell you but you should install there first to configure them to your preferences. They you can use bluetooth to connect them to your Windows devices but I did not find any software support available for the Windows platform, but they did work just fine with the default settings. I will say you will be happier to connect them to your phone and customize how you want to have them to sound for your listening preferences. I have spend hundreds on competitors headphones to have similar features but none are quite up to this level. The ear cups are very comfortable and the materials don't feel like cheap plastic. Once fully charged and with an occasional recharge, these will be ready to go for your listening sessions or a day of work. You can enjoy all types and genres of music, charge them during a restroom break, or when you step away for lunch, then they are ready to go again. The included carrying case means they will last for a very long time and easy to protect during your travels. You can not go wrong with these full feature headphones and if you can ever find them on sale they are easily a can't miss. Highly recommended and should last for many years.

I have used plenty of Sennheiser headphones before but never in the Momentum line before. I have used their CX true wireless earbuds and other various headphones over the years. I never quite liked the look of the older Momentum headphones but I know there is people that do though. These headphones have that modern look like other Active noise cancelling headphones have from other major brands. They have a mix of plastic and metal build which makes it quite light and from the looks better then the older generation of these headphones. Inside the box you get the headphones inside a case which has the USB type A to USB type C cable to charge the device, a 3.5mm to 2.5mm jack cable to use the headphones wired with the 2.5mm going to the headphones. Also comes with an airplane adapter which is good for the few times you might need it. The headphones are able to connect to the Sennheiser connect app which lets you change the EQ, the level of ANC you want to use or transparency mode as well. The headphones also have a sensor which detects if its on you and can pause the music if you take it off. I find it to be too sensitive and I have turned it off since I found it will turn on your headphones inside the case. YMMV. The advertised battery life is 60 hours with ANC on and from what I've seen so far, I am inclined to believe that claim . All in all if you want top tier ANC with the best sound quality These are great. Not the best ANC but close to it.

They’re great! But disappointing when they are $50 and they won’t price match their own add!

i have had these about a week and already the left chanel is conpetely broken and priscues only ear destroying noise. Have used these a grand total of 3 times. Absolute grift. Avoid at all costs. Will be returning.

So good. I think Sennheiser was always too focused on sound quality for music and left comfort and noise canceling be afterthoughts, which let Bose and Sony own much of the market … BUT NOW they have all three dialed in pushing them past the competition. You won’t find a better headset out of the box ready for any situation. The hard shell case is perfectly designed and calls are crystal. The companion app is there for us audiophiles, but factory settings were on point. The battery life is insane. Lasts days and I use these at work constantly. Best luxury all-purpose headphones on the market today. Way to go Sennheiser!!!!

Mediocre headphones, not worth the money. Returned and bought sony headphones.

It was Bought as a gift and the recipient is happy

INITIAL THOUGHTS & SETUP: The packaging is about the most environmentally-friendly packaging I’ve ever seen. You have a package box sealed with two pieces of plastic-based “sealing discs” (this plastic is difficult to avoid, as almost all seals are still made using plastic)…and, upon removing the seals, all I found inside was the headphone case, with everything (headphones, accessories, QuickStart, etc) inside the case. Needless to say, when it comes to packaging, I’ve never been happier. As for setup, anyone who’s ever paired a Bluetooth device won’t have any problems. Bluetooth has, essentially, become “plug & play” at this point. At this point in time, if you can’t figure out how to pair a Bluetooth device, maybe you shouldn’t have a Bluetooth device. I say that, not to be ‘negative’, but to reenforce how incredibly-simple it is to pair Bluetooth devices. SOUND QUALITY: I’ve had a lot…and, I DO mean a LOT…of headphones in my lifetime – those that are plugged in (standard, as well as mini, jack), and Bluetooth. When Bluetooth headphones (by ‘headphones, I mean, literally, the type that have a band crossing over the trop of your head, NOT the type that have the “speakers” sitting inside your ear) first started coming out, audiophiles said they would never rival the sound quality of traditional plug-in headphones…and, at that time, I probably would have agreed, as the sound-quality was mediocre at best. That was approx 20 years ago…and, a LOT has changed in that time. Today, there are multiple ‘quality’ levels of headphones (and earbuds)…some (ie. the cheapest ones) are still mediocre, while others (yup, the expensive ones) that DO rival the sound-quality of plug-in headphones. And, yes, the Sennheiser Momentum 4 Wireless Headphones IS one of them. Honestly, I’m not sure where, exactly, to ‘place’ them in the tier of things. Are they a top-of-the-line mid-range headset…or, are they a bottom-of-the-line high-end headset? The price point they’ve been placed in positions them “on the fence” between these two tiers. Whichever way you decide to look at it, the sound quality is absolutely amazing. For the past few years, my ‘best’ wireless headset has been from another brand also starting with the letter ‘S’ (and having 4 letters in its name)…and, I’ve always thought they sounded incredibly good. The sound quality was great (I’d have given them a 7-8 out of 10 (especially if a ‘10’ would have been what would have been expected from an equally-priced plug-in headset)), and the noise-cancellation was well-above par (I’d give the noise-cancellation an 8 out of 10). Moving over to the new Momentum 4 headphones, I’d say they EASILY deserve an 8…and, possibly, a 9…out of 10. Simply put, they sound MUCH better than that ‘S’-brand pair of headphones. Taking things one step further (ie. something you CAN’T do with that other headphone), Sennheiser has an app called “Smart Control” that not only allows users to customize the sound through equalization, and “sound modes”…but, even better, allows you to completely tailor the sound to your particular liking by asking you, multiple times, to select (between three choices) “which sounds better”. Through this process, the app ‘programs’ the headphones to your preferred “tonality”…and, it stays there, even when not using the app. ADDITIONAL THOUGHTS: So, you’d think all is 100% good with these headphones…and, unfortunately, you’d be wrong. Out of the box, the noise Cancelation didn’t work AT ALL. Between “transparent” and full “ANC”, there are 6 levels…and, even at full “ANC”, outside sounds could still easily be hears. Even after installing the first ‘Firmware Update’, the noise cancelation still didn’t work. Talk about a HUGE “disappointment”…ESPECIALLY for headphones costing as much as these do. Speaking of firmware updates, yes, the Momentum 4 headphones WILL (from time-to-time) have firmware updates…although, how frequently, I cannot say. As I type this review (approx two weeks after receiving the Momentum 4 headphones), the headphones are going through a second firmware update. As soon as the update is complete, I will test the noise cancelation again, and type the results below. In the meantime, while I wait, let me mention something about the installation process of the firmware updates. Unlike many other devices, you CAN use the Momentum 4 headphones during the install process (except, for what should be obvious reasons, when the firmware update is finalizing, as it has to ‘reboot’ the headphones)…but, in doing so, take note that this DOES slow down the update process. The update process “claims” the update will take ’21 minutes’. When I installed the first update, I was simultaneously using the headphones (while watching an episode of Marvel’s “Defender” series), and that ’21 minute’ process actually took almost 45 minutes. As for how long it takes when the headphones are not actually being used, that took (pausing typing until update is complete) POST (2nd) FIRMWARE UPDATE: first, with the headphones not being used, that ‘21minute’ update actually took about 15-16 minutes…or, essentially, half the amount of time it took when the headphones were being used. Second, I can confirm that, with the second firmware update installed, the noise cancelation IS working…and, it’s fantastic. I have the washing machine going, and, with it on full “ANC”, hearing the washing machine is almost impossible…exactly the way it should be. Even in “tapping” a cardboard box only a foot away, I can barely hear it. I don’t know if the noise cancelation was finally “activated” through this most recent update, or if there was some sort of ‘glitch’ in my headphones, which was ‘corrected’ by the latest update…but, whatever the case might be, I don’t care. As long as it’s now working, that’s all I care about. CONCLUSION: I’ll admit, I was initially going to only give the Momentum 4 headphones a 4-star rating. While the sound was incredible, and the battery life was excellent, the fact that the noise cancelation wasn’t working was not only a disappointment, but also lessened my overall opinion of the headphones. However, now that the noise cancelation works, I can ‘return’ that fifth star. I don’t think I need to state, in my review, whether, or not, I would ‘recommend’ the Momentum 4 headphones…and answer SHOULD be obvious. Disclaimer: This product was provided free, or at reduced cost, for the purpose of reviewing the product. Nevertheless, the above review, be it positive, negative, or anywhere in-between, is a 100% honest review, and the price paid played absolutely no part in my review.

I really want to be enamored with these headphones. Historically I have loved Sennheiser headphones. They have the track record for quality. That's why it's so hard for me to write a review having less than 5 stars. But in this case there are just some issues I'm finding difficult to get past. I'll start with the good. For the most part the sound is excellent. I'm amazed by how much more definition I notice when listening to my music with these versus others at the same price point. Out of the box without any eq adjustment they strike a very good balance between lows, mids, and highs. Battery life is definitely as advertised. In fact, I am pleasantly surprised to have gotten even better battery life than advertised actually. The build quality is excellent as you might expect from Sennheiser. They are very comfortable even while wearing for long periods and I say this as someone who wears glasses and whose ears usually start to ache after a while as a result. If comfort is an extra big deal for you, then these are a strong contender. Unfortunately, there are some not so great things about these that have me scratching my head. For instance, I am very surprised to notice that there is distortion when listening to some of my music. I've never had that happen quite like this with a pair of Sennheisers. It is especially prominent when I listened to Bad Wolves cover of Zombie by The Cranberries. At about 60%-70% volume the intro sounds horrible. I was hoping to alleviate this by adjusting the eq, but that lead me to my next two issues. First, the companion app for iPhone is not very good. I have a 12 Pro Max. I have had the app just up and quit on me several times. Other times it just freezes while trying to connect with the headphones and I have to force quit it. But even when it I am able to get past that point, the app still has functionality issues. The in app eq just does not work. No matter what changes I make there is no change to the sound. I don't know why that would be. ANC is also surprisingly an issue. Upon first testing it out I barely noticed a difference with it on or off. The app, at one point, did notify me that there was a firmware update and I did install it, but it didn't appear to have any affect. To sum up, these are very good headphones. There are some puzzlingly not so good things about them. Fortunately I think Sennheiser should be able to address most with updates to the app, but at the $350 price point I (and most people I know) expect headphones without such annoyances out of the box.

Not sure why it is just stop working after 5 months, no sounds at all from this headset now. I am a very light user, only charged this produce once…
