Customer Ratings & Reviews

Really wish I knew this ahead of purchasing them. You can use the 3.5mm aux cable without a full charge, the headphones will work passively with zero battery, BUT there's a catch worth knowing about. The Momentum 4 sounds noticeably worse when the battery is fully drained and the electronics are completely inactive. Plugging straight into a source with the headphones entirely off or out of power produces pretty poor audio quality compared to using them with the headphones powered on. With full battery they are great, best headphones I've ever had, but this feature is a huge drawback for someone who uses headphones a lot or travels long distances. Being tied to a battery for the quality you pay for is a real bummer!

Overall: Would not recommend They worked alright for me. They were used for gaming, music, phonecalls. Sound quality was good for the price. I had owned the Momentum 3 as well. The previous model had issues with motion and touch gestures which could be turned off through the app. The Momentum 4 had the same, unresolved issues with gestures and could not be turned off through the app until a firmware update was released, which was aggravating until such time. I will concede that at the time of writing this, the issue has been resolved but it does show that the engineers were confident with this product but fell flat again. After 9 months of use the headphones have stopped working in one ear completely. I didn't quite use them daily, likely average 4 days a week. It seems ludicrous to buy a $400 pair of headphones and have the customer expect the shelf life to be 9 months. Best Buy has told me they cannot offer any return or exchange at the 9 month mark and having crossed the 1 year mark I lost my ability to use the warranty (my mistake for waiting the extra 3 months to deal with it). I now have a very expensive paperweight. Would not recommend Sennheiser Bluetooth products to anyone.

The first thing I noticed is that the ear curshion feels really cheap compared to Accentum and JBL. Also the headband for some reason irritated my head ( shaved head) but the quality of sound was good and the headphone jack was quite nice. I am returning bc I need long term versatility with my headphones as I use them to edit and to connect to my camera. Less than a month now, I am having issues connecting them to my computer. The hold for 3 seconds to turn on then the hold to connect is too sensitive. I find myself holding and re-holding a lot

I really wanted to love these headphones, especially after spending so much money on them. I've owned Sennheiser products for years with the last pair being Momentum TW 3 earbuds, Which I would recommend to anybody. Pros: - The product feels and looks like it's worth the price, the quality all around seems excellent, it comes with a case, USB-c charger, 3.5mm to 2.5mm cable, and an airplane charger. - The sound quality is excellent and the adjustable Active Noise Cancelling is great. - Phone calls have been clear and problem free. - The Battery life is pretty solid, I can usually get through 3 days of 5-6hours listening (varying levels of ANC). Cons: - The headband is one of the worst headbands I've ever experienced on a pair of headphones, it's angled forward and due to the design it just keeps sliding forward until it's either just sitting over your forehead* or falling in your face. With the headphones sliding forward constantly you lose the Noise Cancelling because the ear cups don't completely cover your ears. So I constantly have to readjust the headphones, l cannot stress how annoying this is. *(I have a large head, so I never imagined this being an issue) - The touch controls are really nice, except that sometimes they just don't work, if you lean over or raise up your arm you'll likely pause the audio by brushing up against your shoulder (you can turn off touch controls, but then you're left controlling playback by pulling out your phone constantly). - The touch controls just stop working randomly, I've had these headphones for over a month and this has happened more times than I can count. - The headphones try to sense when they're on your head (if you take one ear cup off, they will change to let audio in so you can speak to somebody) but the issue is that it regularly cannot determine whether or not it's on your head, which interferes with certain features like double tapping to activate/deactivate ANC, tap to play/pause, squeeze/expand to adjust ANC. So you suddenly can't control anything and taking the headphones off once or twice might fix it. - Using Siri is difficult, you can click the power button once to summon Siri, but there's no audio cue that it's listening and the response is a faint whisper, I have yet to find any solutions for this... I've loved all my previous Sennheiser purchases, this however is the first one I would recommend people avoid, some of the issues could be solved with software updates, but ultimately this product doesn't feel like it passed the testing phase and we're the test audience. I wish I had returned these headphones to buy a better pair, but unfortunately I'm left with these and I hope Sennheiser does better in the future.

I bought these after my Momentum 2s died. They simply sounded so much cleaner and less obnoxiously bassy than the Bose and Sonys. Unfortunately they have the same, and newer, problems as the Momentum 2s. Here's what it's like living with these headphones: You spend 3 days not using them. You want to go for a walk so you pick them up and hold the power button. They turn off. Huh?? Turns out, like always, they've been on for 3 days straight without being connected to any device because no one thought to create an option to have them power down. Oh well, you turn them back on. But oops, you didn't wait long enough so you're just holding the button for 10 seconds while nothing happens. Release and try again; oh hey, now they're in pairing mode instead of on, making this super loud bass-boosted chime. Okay turn them back off. Wait. Hold for 10 seconds and finally they turn on normally. "Connected" says a british woman because a simple chime isn't good enough. The battery life is obscenely good so you're still at 40% battery somehow after them being on all week. "Connected" it says again, connecting to your laptop. You walk out the door, "DISCONNECTED" she says again, interrupting your music. Thanks man, really needed to know that. The ANC is fine, but it suddenly decides that the lowest level should be worse than the second lowest, so you do the pinching motion until you get that level. Oops, you paused by touching the outside when raising your arms to stretch, which you can turn off but don't want to because there's no on-headphone alternative way to do that. Okay, now time to listen to music that sounds a bit duller after a year of ownership (just like the momentum 2's). Does that sound fun? I can tell you, it's not. These things are decent sounding headphones with fine ANC, they are by NO means "high end" and by even fewer means are they worth the absurd asking price, which is $100 higher than when I bought them a year ago. Steer clear, don't buy from Sennheiser and their awful product design team that apparently have no idea what it was like to own headphones that didn't scream at you back in the days of Aux.

I am disappointed with the Bluetooth connectivity with this headset. The pairing often drops, the connection will disconnect suddenly and the headphones are no longer visible on my device list. This requires a repairing each time. This is happening daily. Also, music pauses when you turn your head, voice prompts will advise “disconnected” yet music still plays. I also don’t like the ear cups can’t fold up, just inward. This makes them bulky and hard to store in a bag or seat back pocket. Headphones don’t auto shut off either, despite being a feature in the connection app. Overall I’m going to return these and stick to my QC Ultras. I bought these to rotate usages believing Steinhauser equates to German quality and it appears that is a misnomer. Sound quality is good, However with unstable connection there is no point.

Black Friday “deals” sometimes leads us to making purchases on products we’d otherwise overlook. Being significantly less than the regular price, one may just throw caution to the wind and attempt an insignificant splurge. Well, the Sennheiser Momentum 4 Wireless Headphones was one of (several) “deals” for me, this price slashing season. I’ll just start by saying, I feel for those that paid for these at full listed price. They really fall short in sound quality. Weak- is a perfect word to describe their performance capabilities. Even when adjusting the EQ in the “My Sound” section of the app, as well as adjusting the audio resolution (as well in the app). Just, poor overall audio. I recently, let’s say a few months back, got me a pair of JBL Tune 235NC TWS earbuds, for about $60 (at BB). At first, they too would have been written off (like these Sennheiser’s are in this review), for underwhelming sound. However, after adjusting the EQ to my liking (in JBL’s app), they boasted a significantly better sound than the default. I would go so far to say, having a richer sound than even my Apple AirPods Pro 2’s- which again, come with a much heftier price tag. The comparison of the two (JBL & Sennheiser) comes down to the fact that being able to adjust the product’s default sound, was a significant changer in its perceived quality, as far as it’s fundamental function of producing sound. It’s laughable that a product like the Momemtum 4 with a price near the $400 (at regular) mark, is compared to, and bested IMO by a product several hundred dollars less at base value. Once a product’s intended function has missed the mark, everything else about it isn’t even worth acknowledging. I mean, these headphones are comfortable, I guess. The controls are relatively simple. I would compare the Momemtum 4, honestly, to Beats Studio Pro Wireless Headphones. Same build material quality, same price range (at regular), same underwhelming/ disappointing audio quality.

So, after test driving them for a couple weeks, I found myself disappointed. I had researched headphones for days and these seemed to promise everything I was looking for. I make podcasts and intricate audio files with sound effects. I was concerned about the wireless aspect, but reviews assured me it had no impact. That turned out to be very much not the case. It came with an audio jack so I figured I could at least plug it in if the wireless lagged. First off, I really dislike the design. The touch screen-like buttons on the side to control everything is so confusing and sensitive and I'm constantly touching it accidently. I hate that I can't turn it off on my own. It automatically turns on when you touch it. So when I turn off the power button and try to set it down, it comes back on. I tried to do some work with them, but just as I was worried about, the jarring in and clicking from headphones trying to keep up with the editing software made it difficult to work with. So I tried using the usb wire, which by the way both wires are short. Not nearly long enough for computer use. I couldn't get the computer to detect the usb consistently. Sometimes it would and sometimes it wouldn't which lead to half an hour of frustration some days. I wanted to use usb because I had a longer wire for it. So I was stuck using the short jack. That worked okay but still felt like it was clicking when audio began from silence. But then I encountered a problem with the lack of software for the computer. There are no downloads for it. You can only adjust things through the phone app. But if its plugged into your computer its doesn't work. So you can't adjust anything. As for the sound quality, it was better than what I previously had which was a shark, a decent headset, ranging about $125. But the quality wasn't as mind blowing as I was expecting for a $300 pair of headphones. I splurged on them because I thought they were going to help me make my audios precise and phenomenal sounding. The sound fluctuates. It seems to sound louder some days than others, which causes me to turn up the volume of the files in program, then have to turn them back down in editing on different day. I tried to like them but found myself having buyers regret. I have decided to return them. I can't stand it anymore. These might be fine for listening with your phone, but that's pretty much it. If I had to value them, I would say about $89. Not $300. I have a pair of wireless skull candy for $150 that sound much better. I found some studio headphones so going to try them out. I understand these weren't labeled as studio, but I was hoping the quality was so fantastic it didn't matter. I was wrong.

I dont write reviews, but I felt compelled to write this one. I loved sound on these day one, but after 4 months of limited airplane use they clip on every song. They are no useless. I "upgraded" from 3 year old Sony WH-1000XM3. The sound is better on the Momentum 4, but it did not last long. The fit feels cheaper and they are not as comfortable as the Sony, but it was worth the sound upgrade & I liked their app. the Momentum 4 has a hard time shutting off and going in the its case. When you put it in the case, it turns back on. The case and accessories were the same good quality as my Sony's. I am not returning the product for warranty and I have to pay to send it to them. VERY DIFFERENT than Sony which sends you new phones and you dont pay the shipping. You cannot talk to a live person and their support page is horrible.

I really wanted to love these, they sound great and they're really comfy. I usually pick Sennheiser for most of my audio but these still seem to have a significant issue with any moisture. I never even wore them to work out. Just watching TV in a warm apartment (I have a lot of background noise so ANC is a godsend). One day was a bit warmer than usual and I found myself sweating a little. Next thing I noticed was a loud pop in the earcups, like the sound of a stereo at max volume suddenly turning off. And they just power cycle now. Despite a fair bit of troubleshooting, the device never recovered before I returned it.

Sound Quality very good. But the product keeps on falling from your head. The connection keeps on jumping and the touch controls are extremely sensitive and you have to restart t the app each time for it to work.

I debated between the Momentum 4, the Sony WH-1000XM4, and Sony WH-1000XM5. I tried out both Sony XM4 and XM5 in the store but wasn't wowed by either. I have an HD-555 that I love but they're broken so figured on top of my Airpod Pros, I wanted I pair of over ear headphones. I was able to get these on sale around Thanksgiving. When I started using them they sounded great but I noticed the volume even at max wasn't that loud. On top of that I could hear my tv while I was testing these out. I borrowed my brothers Sony XM4 and could tell the noise cancelling was significantly better. (I couldn't hear the tv) and the sound was louder without being at max. Since the sound quality wasn't horribly worse, and at over $100 cheaper since its been on sale everywhere I opted to return the Momentum 4 and get the Sony XM4. so disappointed since I love Sennheisers.

The headphones have great noise cancellation and can also have great sound (if you adjust the equalizer). However, the headphone software is very flakey. Connections come and go and the operation of the software keeps changing without user input. I set the ANC at full, touch controls off and adjust the EQ. Using the headphones through the hours I find that touch controls are re-enabled randomly, ANC varies and connections are dropped - frequently. Perhaps I got a dud, but looking at the other reviews I find that these headphones have had problems for quite a while. You would have thought that Sennheiser would get their act together by now. I will be swapping these out for another and see how that goes.

I hate to give these headphones such a low score, but I wish I had never bought them. The sound is great. The headphones in general are great. My issue is that they have an annoying "feature". They have an auto turn on that has no rhyme or reason as to when it connects. The most annoying part is I'll be on my phone with someone and all of a sudden these headphones turn on and connect, even though they have been siting in their case and not touched at all. Anytime I go anywhere with them I have to unpair them and then pair them when I want to use them. All because someone thought it would be a neat idea to get rid of manually turning on and off headphones. It's the stupidest flaw ever. Their app does not have an option to disable auto turn on. I'll be using my galaxy earbuds, and my phone will switch over to the momentums even though I didn't touch them or take them out of their case. It's especially annoying when I'm hands free in my car and my phone will be connected to earbuds or my car speaker, and all of a sudden it will switch over to the Momentums. The only way to prevent this is to unpair these headphones everytime you're done using them. This has been an ongoing problem for years. I guess I just didn't do enough research before buying these headphones. I wish I had bought the Bose

Audio quality is superb and the battery life is generally impressive, but the connection issues are so frequent and annoying that I cannot recommend these to anyone without the huge caveat that they'll likely need to run them wired. I have an external Bluetooth adapter in order to get better signal and that's the only reason these are even able to transmit sound at all, without it they were a choppy mess. Sticking to wired from here on out.

When they stay connected they sound good. They easily disconnect everytime I get a phone call. I have to go into the bluetooth on the iPhone and reset the connection. The microphone isn’t great. The touch controls are awkward and easily triggered. I tried to return them thinking I had 30 days, i did not know you needed to buy the membership from Best Buy. Turns out it was only 15 days. I was 8 days late trying to return them. So i am stuck with an over priced quirky set of headphones.

I Was not impressed. So many great reviews I've seen about these headphones, so i was very excited to try them out. I was shocked at how below average these sounded. The bass was average, the music sounded cloudy and thin. And the volume is not really loud. I love the details in the build quality. For $400 these were a let down. I returned them the same day.

https://www.reddit.com/r/sennheiser/comments/16vgka2/popping_and_crackling_on_momentum_4/ Follow that! The sound quality is good dont get me wrong, You are not gamimng clearly on these withot additional configs tho. It layers with other game audio stuff and causes voices to be muffled and sounds to tunnel. For just listening its fine. BUT the 2/5 stars is because it crackles and pops during peaks in audio including video calls. Follow the above reddit post to fix. If you are a technical person with computer literacy you can fix it. Otherwise return these bad boys

I have had nothing but problems with these. Sound is fine, but the touch controls are horrible. I have had nothing but issues with them stopping, volume changing etc and I'm not touching them at all. I went to far to turn off all touch controls in the app and the volume would still automatically go down or pause the music even though I turned off the wear detection.

Frequently loses connection with Bluetooth sound good but overpriced
