I'm guessing I am coming at this from a different perspective than most people. My main headphones are the incredible Sennheiser Hd650s with a DAC/tube amp.

But I wanted a pair good for traveling. One of my biggest complaints with active noise cancelling headphones is the sound quality has often been sacrificed in the name of quite. These Momentums have had no sacrifice in the sound quality department. Are they as good as HD650s? No, but the philosophies behind them are completely difference. The soundstage is the biggest difference where the Momentum's do sound a bit sterile and like you're in a basement or recording studio, but completely in line with other ANC headphones.

But connectivity across multiple devices was easy. The accessories that this comes with are also really helpful. A carrying case, a charger cable, an aux cord for computer/planes, and an adapter.

The sensor allows for auto pausing music or muting calls if you take your headphones off. Sometimes it's a little wonky, but it's never annoying. The touch sensor sometimes self disables, but otherwise it's helpful to be able to control without your phone/device.

Getting the Sennheiser app allows for a graphic equalizer (5 band fully customizable) and customization of how much noise control you have, so in quieter environments you can open up the soundstage. The app also has a bass boost which is a nice feature. It's nice to have that level of customization, even if for most of the time, I'm using them for traveling with full noise cancelling effect.

I used them on planes recently and it pretty much completely blocked out the ambient engine noise. The announcements were sometimes barely audible depending on how loud the music was. A really loud baby cry did get through.

They're reasonably comfortable, just a small amount of pressure after a few hours.

I was surprised this product has a 4.1 average given my experience with these headphones. Zero issues that some of the negative reviews described.

* I wouldn't use these for exercising without changing the ear pads, they're a leathery material and I suspect you'd ruin them quickly with sweat.

After having these headphones for the past year, I have to say that these are definitely 5/5 headphones. I'm not sure what some of the complaints are about, but I think some folks with the lesser reviews must have gotten faulty devices, because the only time I've ever had a connectivity issue was when I mistakenly had both my speakers and my headphones connected. As a matter of fact, I've actually found myself more annoyed by them automatically turning on and connecting when I had literally just turned them off to put them away.

There's something about the "on-ear" function that senses when you're wearing them. When the ear muffs go face down in the case, the headphones will sometimes think that they're being put on your head. If you're doing it in a fluid manner, they won't turn back on, but if you turn them off, set them down, and then put them away shortly after, they'll probably turn on.

I believe the noise cancellation is solid. When I don't have any music playing and just have the noise cancellation active I can't hear much at all. Normal conversation is definitely out of the realm of possibility. If someone's talking to you and you're not looking straight at them, you wouldn't know it. You can hear some of the louder traffic that passes by if you're walking down the street, but if you have your music on you're not very likely to hear anything but larger/louder vehicles. I would say sound over 80 dB and you can start to hear things through the noise cancellation.

I've used these for casual gaming on my PS5. You have to connect the headphones directly into the controller, but I'm pretty sure that's just a Sony thing so that you'll buy their PS5-specific headphones. Anybody I've played with has never complained about not being able to hear me and anyone I've asked says I come through clearly. I asked people specifically to know if they would work well with games as well as music, and I think they're great for both.

There is good spatial sound. In video games you can hear things like directional footsteps and know whether someone is in front of you, coming around a corner, or behind you. With music you'll hear background sounds that the recording picked up or different notes or instruments that you've never heard before in songs you've heard a hundred times.

Now, let me be very clear here: these are not $1,000+ "audiophile" hardwired, gold plated, top-of-line headphones for top-quality production. I'm just a regular consumer who loves to listen to good music, with great volume, bass, and body. For all practical purposes, these are absolutely fantastic.

The size of the headphones is reasonable. Not too big, not too small. I've seen some complaints about the ear cups being too small, which from one standpoint I understand. On the other hand, they're actually really comfortable. The material is soft, the headband is comfortable, they're adjustable, and for me, they've never been too tight. They were maybe a bit tight for the first week or so I had them, but nothing memorable or headache inducing.

The material on the ear cups, while comfortable and soft, does make me wonder when, not if, the material starts to break down. If you sweat, prepare for your ears to get hot and sweat. The material isn't absorbent at all, so you don't have to worry about your headphones getting soggy, but sweat will definitely build up on the cups and it can become a little uncomfortable if you're walking in a bit of heat. On the same note of not being too tight on your head, they're also not terribly heavy. I think they weigh a bit more than the old school Beats - when they were still owned by Dre - but I can say they're far, far superior to the Beats. You can feel it and you can hear it.

The case they come in is solid and compact - as compact as it can get for headphones that don't fold in half. It fits in my backpack just fine and it definitely won't get crushed unless you're really trying to damage the case. It would take a full body fall and the case's first thing to give way would be the zipper. Even then, there's not a wide enough range for the case to entirely break down and crush the headphones. I believe that if you slipped on ice, for example, and fell straight on them, they would survive.

I compared these to the XM5's and I think these have a deeper bass. I think the soundstage/spatial sound is more in depth with the XM5's, but you most likely wouldn't be able to tell unless you've got a very keen ear or you're directly comparing them side by side.

I have no idea why these are currently priced at $450. A year ago I spent around $300 for them. It was a great deal then, and I would probably spend $400 again if I ever needed to replace them. If I do look to get "nicer" headphones, Sennheiser will definitely be a brand I'll look for first.

The software for Sennheiser is not that great, but it's been improving since I got the headphones. You can adjust noise cancellation, wind cancellation, highs, mids, lows, bass, etc. You can adjust your functionality, such as how your touch controls function on the outside of your headphones - swiping up will turn the volume up, tapping it will pause the music and so on. You can answer or decline calls with it, but I just do that on my phone to not accidentally pick up a phone call I don't want. If you have your own settings and you've got them turned up beyond what they reasonably can do, you'll sometimes get a skip in one of the speakers. Mine just so happens to occur in the left ear, but once I corrected my settings it stopped happening.

I do wish the volume could be turned up another notch, but I'm pretty sure if they were to go any louder then they would cause real hearing damage after about 20-30 minutes. I listen to my music loud and have had no worries about hearing damage, which I've been paying for as time goes on, but if you adhere to realistic settings then you will be just fine. If you start to go over on your setting boosts in certain categories, you'll hear it start to get a little muddy or tinny depending on the setting. If you hear either of those, even a little bit, change your settings.

The first firmware update took 10 or 15 minutes and your phone screen has to stay on during the download and installation otherwise it will cut out for some reason. So plug in your phone and make sure you have your screen on and the app open for the duration otherwise it gets interrupted. It took me a couple tries to realize that.

For anybody looking for headphones in the sub <$500 range, these are almost perfect. Mine get regular use, the battery is just insane, the sound quality is solid and comes through in a consistent manner. You can tell when a song has been recorded or produced on a lesser scale than some others. They can really make certain artists/songs/producers stand out more than others. They also play every genre of music well. If you think of a sound system, a 12" sub will have a slower reaction time than a 10" sub, for example, so if your hip hop sounds better on a 12" and your tighter bass sounds come through a bit better on a 10" sub, these headphones feel to be right down the middle. I say "feel" and not "sound" because if you've ever had a sound system in your car then you know the vibrations you get from that strong, amplified bass through your subs. You can almost replicate that feeling with good headphones and these don't weigh heavily one way or the other.

These headphones were exactly what I was looking for! Not my first pair of Sennheiser headphones, but definitely an upgrade from my last pair. They are quite comfortable, my ears are quite sensitive and these cause no discomfort whatsoever. They are great on an airplane for blocking out the worst of the engine noise. I love that these have such a long lasting battery as well as I am forgetful and don't always remember to charge them frequently. They are not heavy on my head and the padded top makes the fit very well. I have had 0 issues with connecting these to my devices, and I do enjoy the touch controls as they are the same as my last pair of Sennheiser headphones, it's great being able to skip, replay, adjust the volume, and pause/play my music without having my get my phone out! Oh and they sound incredible as well, very high quality sound with lots of options in the app to adjust to your desired preferences!

I had the most annoying week+ of trying to make this BEAUTIFUL headset work.

I really wanted these to work.

But you can only try soo many Reddit fixes before you're beyond pissed off and completely over it.

First: I couldn't hear the trial music they play on the app when you first set up your sound profile.

It was silent.

Removing and re-downloading the app didn't help.

I disconnected the headset from everything, reset my phone, and tried 4-5 more times before I got anything to play. When it played, it was too quiet to change anything meaningfully.

Second: This headset gives you 6 options in your sound section to choose from, which is annoying.

Some are named the exact same and do absolutely nothing when chosen.

The most annoying part was the only option that provides side tone will give you the worst quality sound you've heard since your 90s Walkman- - paired with that tiny round headset you found at goodwill or in your garage.

To use this headset with side tone and have decent sound, you have to disconnect the mic in your computer settings all together and use another mic that will provide you side tone Now you need more gear or a mixer to connect your headset to your mic. The whole ass point of this headset was to game with friends, or be able to answer phone calls while being productive around the house.

It's hard for me to function socially when I don't have side tone. That's on me but...come on. This was an expensive purchase. It should be able to do both... like my $80 Corsairs do easily.

Forget hearing footsteps. If you're on discord using the headset's mic, your sound quality doesn't allow for differentiation between spells in an ARPG.. or footsteps in a pvp game.

You cannot use the headset for talking and receive quality sound. I wouldn't even say quality. They are simply unusable.

Thirdly: Speaking of my Corsairs, they were LOUD at volume 30. I've probably never gone over 50 on those.

With this set, I had to be on 95-100 to get where my previous headset would've sat at 20.

What.

I could NOT get any volume out of these and I tried enough things to make you hush.

- -you, who is saying I did something wrong or skipped a step. No. Nope.

I did it all and it was over a week of futzing, alll the trial and error before I finally sent them back.

Which was sad because I've lusted after Sennheiser for ages.

Even when I was finally able to adjust my sound profile in the app, I couldn't get them to be loud enough with clear sound to function. I opted for my air pods over these and if you've ever done that on your gaming computer, air pods sound like you're inside a dumpster 40 ft away. I preferred this to the Sennheisers. Sad.

Reason four: They dropped all Bluetooth connections 10+ times a day. My house is 745sq ft so even if I was walking around my house and not sitting at the desk with my phone/computer next to me, they should have worked for most of the home. At the very least, I should have been able to go 10ft away from devices. Nope.

They didn't stay connected even directly next to devices-- for reasons I couldn't figure out. So forget about any movement. No trip to the fridge 8 feet away between matches.

I was stupidly willing to look past this part because, like I mentioned above, I was lusting after these for a while before finally shelling out the dough.

If I could just tap the Bluetooth button to quickly reconnect devices, I would have suffered with my snazzy Sennheisers.

But when this happened, I'd have to restart my phone, restart/reconnect the headset, and reconnect phone Bluetooth.

I even had to redownload the app to be able to connect two separate times.

For the computer, I'd have to go through the process of finding/connecting the device after resetting, and then selecting the proper option in the drop-down sound options on my computer which changed places and was super annoying. This took way too long, especially if I was on a call or in game.

Having to tab out of a game to go through that.. sometimes every hour... was maddening and I def lost a lot of matches and did a few desk-slams.

Eff that.

Five: In addition to costing a lot of money and being absolutely useless for my purposes (or any purpose), this headset also had unreliable manual touch options on the side. They only functioned half the time. Joy.

Six: I reached out to Sennheiser for assistance and advice on day one. It was possible I simply needed a replacement after scouring their FAQ on the website.

They returned my enquiry 28 days after I sent them a request. This was almost 3 weeks AFTER I had returned them. And this wasn't during the holidays.

28 days later and with a bunch of garbage. An unhelpful reply that had nothing to do with the issue I had selected in their drop down options. Like. Not even remotely helpful. Did they read the ticket?

There's no way.

Maybe I had a faulty pair? Who knows but I think probably not because I found a shocking amount of people that had the exact same issues.

These should have been recalled but enough people will stubbornly make them work and the company still makes money off those who don't return them in the end, either from laziness or denial

or an abundance of money so they don't need to make the effort :P

1 star for aesthetics/battery life. I did not have to charge them once- out of the box- and I did a lot of troubleshooting in that time.

They are comfy, yes, but I now have a cheaper pair of Logitecs that are comfier with an equivalent battery life.

I gave up on the multi-device idea and went with the Logitec Pro x 2 with LIGHTSPEED

These were plug and play. No BS. Comfy, sharp looking, work AMAZING with discord and whatever else I've connected them to.

I'll stick with swapping out my headset for my airpods for phonecalls for now because we just aren't reliably there yet, it seems.

I gravitated towards these set of headphones🎧 because of the reputation of the brands name and just by the appearance alone. I’m in love with the color scheme that they’ve chosen 😍. White and gray never looked so amazing.

The touch controls are a nice feature too. I enjoy using them. It’s not complicated not one bit in my personal opinion and experience.

The sound quality is pretty good.

I don’t know how to intelligently break down frequencies so you’ll have to find an expert who heard these babies to go into detail.

I did check out some of my favorite Southern Rap songs to hear how that bass hit and I can say that I wasn’t disappointed and the highs were jamming right too while listening to hi hats in TRAP MUSIC

But I am a bit worried about the longevity of these very pricey beauties.

The R, L, and headphone name that are locating inside of the ear cup will eventually wear off and that’s the very least of what I worry about. I’m also knowing that the ear cups themselves will wear out as well and start to rip and tear apart just like the other headphones that I’ve spent over $100+ bucks on! Limited warranty’s usually don’t cover replacing worn out ear cups as long as there’s no shortage in them which could cause you to not be able to hear equally out of both of them.

The connectivity issues also can be so annoying at times and these are my second pair by the way!

I returned the first pair because of connectivity problems.

The headphones may often disconnect wirelessly while I’m listening to music or watching something on YouTube.

I get so aggravated about it!

REVISED UPDATE (1/4/24):

There’s been times I’ve pressed or tapped on the right cup and it would not pause the music especially after the headphones 🎧 randomly disconnects for some reason and I would have to power them off and power them back on then reconnect them AGAIN for them to do some type of reset.

The connectivity isssues can be so annoying at times and these are my second pair by the way! 🙄

I returned the first pair because of connectivity problems.

The headphones may often disconnect wirelessly while I’m listening to music or watching something on YouTube then I would have to hold the button that under the right ear cup until the headphones says connected, smh 🤦🏾‍♂️

These headphones are too pricy to have this kind of bug issue I MUST SAY!!!!

The sound quality is pretty good, though.

That’s why I bought them again after I returned the first pair hoping that I just had a bad set of headphones but I’m currently facing the same problem.

The lows, mids, and highs sound really great in my opinion.

I was thinking about returning them again and I was going to try another color and see if I would experience the same problem. 🤔

I was also thinking about getting a refund and exchanging them for the Sony WH-1000XM5’s and so I could test them out.

Amazing pair of headphone, good sound quality. The noise cancellation is top but not as superior as Sony or Bose higher end. I love the color and build quality. Some said that the headband is tight or hard on their head but i have no issue with that. As the M5 is coming out, this is still a solid choice for price under 200 if you find it on sale. The material on the headband is prone to scratch so take good care of it. It is true that the headphone does feel quite hot after a few hours of usage, but it depends on the room temperature. I have no big deal when wearing them in AC room but walking with the M4 outside sunny does feel hot. I mean it is the same for all headphone due to their physical build of over ear. One more thing, when you take the headphone off and rest it on your shoulder, it does feel tight and not as comfortable as other headphones. Overall, this is a solid choice for sound quality, and build. If you are looking for NC, then it wont be the top notch but still very good. If you are looking at Xm4, xm5 or bose, give all of them a try. I still think M4 is the sweat-spot for price, sound quality and NC.

(also they come with a hardcase+wire but not the one with microphone, you need a separate microphone or turn them on to use with bluetooth + charging cable+ airplane adaptor) This is my personal experience as a tech lover, not an expert review.

The good:

- The Sound is great in my opinion, I'm not an audiophile, but I do enjoy quality sound.

- Battery life is amazing. I'm talking days without charging using all day.

- Mostly comfortable, which is something I was concerned with.

- Bluetooth seems reliable, occasional disconnects, but I attribute that to my tablet as it's range seems limited.

- Fit and Finish: I've had quite a few over the ear headphones and Senheiser put thought into this and did a decent job in my opinion so I thought I'd put at least a little thought into my response to this.

- The cushions on the cups going around the ears are comfortable. They're soft, and just cushy enough. They did a great job with this. Many headsets are often too hard, not enough cushion, a weird material, or just not comfortable for some other reason. Maybe I'm just too picky...

- Depth of cups plus cushion is okay, and they'er angled to fit the profile of your ear instead of just a flat cup. My ears don't stick out a ton, but they do a little bit. I've never had a over the ear headphones that didn't cause chafing or iritation over time. Unfortunately Senheisers are no different here. They do have a softer foam in the cups than I've seen in other cups, and I'm sure the angled cups help so I give them credit for that. It would be nice if the angle were a little deeper, or if they had some sort of add on to extension for those with wider ear bases but still they are more comfortable then most other headsets I've had.

- The band is decent. I don't know about you, but after wearing headphones for a while that band can eventually start to feel like it's hold a bag of rocks above your skull. Senheiser uses what I assume is a silicon material with an okay amount of what I assume is memory foam. I think they could have used slightly more dense memory foam or maybe a little bit more of whatever they use now. They certainly could have had more around the corners of the band. I still feel that band against my skull and wish I didn't. It is better than many other headsets with little to no cushion or the crappy elastic band that wears out after a week and ends up being crappy padding against metal.

- The finish itself is decent. The cups sleek and clean. No significant gaps, and it doesn't feel cheaply made. The top is a cloth material that is nice, but can attract pet hair and lint. The Senheiser symbols on the band are small and ever so slightly sharp. I doubt enough to cut you unless you wack them pretty hard by accident, but they could have softened that a touch more I think. For those that are blind, there's a braille L on the inside of the left band denoting the left side for you, I have never seen this before or at least never noticed it, so I'm giving Seheiser props for this.

The bad:

- The touch controls on the right ear cup are awful, I'm not talking about the gestures and how they work, they're WAY too sensitive. I wear hoodies a lot, and my hood would set them off constantly and eventually I just disabled it all together so I never even had a chance to really learn the gestures.

- They're a little heavy. Not terrible, just more than I'd prefer, but that's the cost of quality and battery life I guess.

The beige:

- Noise canceling isn't bad, per se, I think they could have done better, especially at this price point.

- Price: I'm torn on the price. I like the headphones especially the battery life and sound. The comfort is better than most, but mostly around the ear pads.

Improvements where I could see fit the price point:

Better padding in the band

Better foam in the cups

Make extension or something for wider ear base

Better noise canceling

Less Sensitive touch pad, a more limited the touch pad area, and maybe limit the material that can interact with the touch pad.

Some asides. The android app works on de-googled android devices. This is 100% a plus to me. I wish it were opensource, or they made it available outside of google play store, but can't get everything you wish for I guess.

The Sennheiser Momentum 4s are excellent all-around wireless headphones and an outstanding value in this price range. I compared them directly with the more expensive Apple AirPods Max 2, and I preferred the Momentum 4s about 75% of the time. They have a warmer sound and better bass, although the noise cancellation is only fair.

The Sennheiser app includes a five-band EQ that lets you customize the sound to your listening preferences, along with presets for different types of music. I found this to be a game-changer.

For critical listening, the Momentum 4s offer a wide soundstage with excellent instrument separation. The 60-hour battery life may also be the best available. Overall, they provide an excellent combination of sound quality, battery life and value.

I highly recommend them for serious listeners. I ultimately returned mine, but only because I was so impressed that they inspired me to upgrade to Sennheiser’s more expensive HDB 630s.

Je suis très satisfaite de mon casque, qui est très confortable et fonctionne très bien.

Le son est magnifique, et le prix était raisonnable quand je l’ai acheté.

Amazing headset and holds up with all the big brands. Unfortunately doses not connect to PS5 Pro, regardless of whatever USB C dongle you use.
