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.

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!

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.

I'm borderline obsessed with Sennheiser, and gave these headphones an honest try; I really wanted to like them, but until they fix the firmware, I couldn't recommend these to anyone. Tested on multiple devices, all of which are up to date. To future-proof my review (because I won't remember to edit my review once the firmware problems have been addressed), I rated these 4 stars based on the assumption that there will be a future fix to the firmware problems. If taking the firmware into account, I think I'd rate these 2 stars (as of 8/31/2022). Pros: These headphones have quality sound, probably on par with the price point. Not significantly better than my PXC 550-II's, but they do have a bit more depth and bass. Their noise cancellation is good, but not as good as my Bose QC35’s, which is to be expected. The battery life is incredible. I don't think I'm getting 60 hours (volume kept at around 20-40%), but they're still awesome. Cons: These are nowhere near as comfortable as my Sennheiser PXC 550-II headphones. They put more pressure on my ears/temples, and the headband is way firmer. My head is aching after about 30 minutes of use. There are significant firmware issues (my firmware is up to date, as of 8/31/22): When using the auto power off mode, they turn on (and sync to your phone) any time they’re moved. This will of course silence your phone’s alerts, as they’re playing over the headphones that you didn’t mean to turn on. When using the on-head detection, they keep turning on and off while they're sitting around my neck. Whenever I answer my phone (iPhone 12 Pro Max) and change the output to these headphones it just hangs up the phone. Haven't tried answering using the headphone's touch controls, it's possible that would work. While the transparency mode is a nice feature, it's almost laughable compared to my AirPod Pro's and Sony WF-1000XM4's. It sounds just barely better than wearing non-noise cancelling headphones. These can connect to 2 devices at a time, but when switching between paired (and connected) devices (for example: listening to audio on my tablet, when I get a text alert on my phone, which interrupts tablet audio for a second, before switching back to tablet again), and whenever I answer my phone, as mentioned above, audio quits playing over my headphones. My phone says it's still connected, but it doesn't show up as an output in any apps. I have to reconnect it to my phone to get it working again. Whenever I pair them with a new device, it disconnects from existing connected devices. I have to reconnect afterward. As much as I want to like these headphones, until Sennheiser fixes these software issues, it's just not worth the hassle.

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 wanted a pretty nice set of bluetooth over the ear noise canceling headphones. I specifically waited for Black Friday so I could get a nice discount. I bought four different sets of headphones that were in my budget to try them all. I kept these sennheiser momentum 4 over the other ones. I returned the other three which were the Sony 1000 XM5, the Bose QuietComfort ultra and the Bowers & Wilkins Px7 S2e. All of these had a similar price when not on sale. I was quite surprised that I kept the Sennheiser. I really thought I'd be keeping the Bowers and Wilkins based on some of the reviews I've watched. For the type of music I listen to and the ways I will be using these headphones these were just the best. The app is solid and has lots of nice options and allows for the kind of customization I was looking for. The fit is perfect for me. Although so were the Bowers & Wilkins. But the sennheiser's battery life and sound profile along with the nice noise canceling, not the best noise canceling but really good, are what won it over for me. A real 60 hours of battery life is just incredible. That means the average person probably wouldn't have to charge these but once a month! They also came with a really nice case that's slim and easy to throw in a backpack or bag. I'm not sure why other people have issues with the touch controls, they work perfect for me. And the sound quality for the type of music I listen to which is mostly 80s and '90s metal is phenomenal for Bluetooth headphones. I have a few sets of really nice wired headphones and IEM's and these are quite surprising how good they are. A friend of mine has the bose and I've let him try these. He understands why I pick these over the bose now that he's heard them. The cherry on top for these headphones though is that they are phenomenal when you're making phone calls. It doesn't matter how loud or windy the environment is that you're making your call in, the person on the other end has no idea as it's as clear as it ever could be when using Bluetooth. I am really amazed how well they work in this regard. Bluetooth headphones are very subjective when trying to tell someone what is recommended. And if I wouldn't have tried these four I would not have believed how much of a difference there is in the sound profile, comfort, apps, and noise canceling. If you're going to spend some decent money on a set of headphones I really recommend buying a few sets or at least going to a store where you can try them first. I know that's hard to do as most places don't let you try before you buy, so that's why I bought all four and returned the three I did not choose. I've used them with my Hiby DAP, my pixel smartphone and my Lenovo tablet as well as my Sony TV. All of them work fantastic and the connection was quick and easy. I like the fact that I can set up different sound profiles in the app based on what I'm using the headphones for. I have one for podcasts which makes voices sound clear and precise. I have another for movies with the extra bass turned on for the impact of movie soundtrackcs and the punch for explosions and such. I also have another for my favorite kind of music and I have one for watching YouTube videos. I'm not trying to convince anyone to buy these, I'm just telling you my experience with the forehead phones I purchased and why I chose these. Everyone is different, so what's best for me is not necessarily what's best for you.

After over three years with these headphones, I feel like it is time to give an honest review. I have owned many headphones over the last five decades, made by several manufacturers. The three brands that have stood out as the best, and come with reasonable prices, giving me the most satisfaction have been the professional grade headphones made by BeyerDynamic (whom I consider the best overall), Sennheiser, and Sony. Note I said PROFESSIONAL Grade. None of these brands, nor any brand, of consumer grade headphones, will be great. That isn't what consumer grade headphones are made for. This is unequivocally true of any form of wireless headphones, especially Bluetooth, as the technology is simply impossible to make as high quality as wired. My experience with consumer grade headphones is limited, as I am a musician, and love to listen to Jazz, Classical, and Progressive Rock, which are all music types that are best experienced with true high-fidelity audio equipment, though you need not go insane with the ultra-premium audiophile junk that is marketed with baseless and often downright dishonest BS associated. Just solid copper wiring, well engineered amps with over-spec'd solid state components (or if you prefer the warmth of tubes like I do, go with tube circuitry). Note, I never wear headphones in public - I don't like looking like a martian or an idiot as some people seem to do. Rather, I listen to music at home, and as such, only listen using professional "audiophile" grade wired over the ear, open-back headphones in an otherwise silent room for the most pristine listening experience. So, with all that said, it should be noted that these are not TRUE Sennheiser headphones, but merely Sennheiser branded, under license, that are NOT MADE BY SENNHEISER, but rather made through a partnership with Sonova Holding AG, a Swiss hearing aid company that acquired Sennheiser's consumer audio division (including wireless headphones and soundbars) in 2021, with the two companies collaborating to continue the brand's consumer products, while the original Sennheiser remains focused on professional audio. Sennheiser's wired headphones, especially their high-end audiophile models (like the HD 600, HD 800 S, IE 600, IE 900) and professional gear, are still made by the original Sennheiser electronic GmbH & Co. KG, a German company focused on Pro Audio and high-end wired consumer gear, while their general consumer wireless headphones are developed by Sonova AG under license, following Sonova's 2021 acquisition of Sennheiser's consumer division. Key Distinction: Sennheiser (the original company): Still German-owned, focuses on professional audio (microphones, conference tech) and high-end, audiophile wired headphones, manufactured in places like Ireland. Sennheiser-hearing.com (Sonova): The consumer side (wireless headphones, soundbars) is operated by Swiss hearing aid giant Sonova, using the Sennheiser brand name under license for their audio products. So, if you're looking at premium wired headphones from Sennheiser, look to the wired HD 600 series or IE series, as they're from the original Sennheiser; and if you are looking for Bluetooth headphones, be aware that the Sennheiser brand is only a name and does not reflect on the quality that Sennheiser has long been known for as they are from the Sonova-operated consumer headphone division. Likewise, be aware that bluetooth is a VERY problematic technology, with frequent problems with connecting devices, random disconnects and audio dropouts, glitches and noise. In short, bluetooth with NEVER give you professional grade audio. Note that whilst you CAN connect these headphones using an audio cable, you will not get true Sennheiser quality audio out of them, as they just are not true Sennheiser headphones and have lower quality drivers (what the the actual speakers are called), and the audio circuitry remains part of the circuit. Pros: Acceptable, arguably above average audio quality - though this is a VERY subjective matter, and is especially present when used as wired headphones, but DO NOT EXPECT Sennheiser pro grade audio out of these. You will NEVER get that out of Sennheiser or ANY Bluetooth headphones as Bluetooth and the digital circuitry is inherently trouble prone, even with a direct wired connection, as the electronics introduce both active (crosstalk interference when powered on) and passive (impedance issues due to inevitable circuit design). The noise suppression is okay, but definitely below par. Both Bose and Sony do significantly better in this regard. Build quality is another major issue with these headphones. The padding comes apart as it is merely glued, and whilst the ear pads are replaceable, the only available replacements appear to be third party. However, the headband pad also comes loose - I was able to repair mine using a a syringe loaded with glue, and a metal spudger to tuck the fabric back under the edge. Not optimal, but workable.

Bought these along with the Sony XM5 to compare to my existing Bose 700. Comfort: The Bose 700 I don't find very comfortable, namely the headband, being rather thin, it puts pressure on the top of my head after a couple hours. The Sony had this problem initially, but then I started loosening the headband as much as possible, and being a very light pair, I stopped having that particular issue. All in all I found the Sony much more comfortable than the 700. I could see some folks saying it's more comfortable than the Momentum 4s. However I disagree about that. For me the Momentum 4 are the most comfortable. It has very soft ear pads, much like the Sony. Granted the M4s are heavier, but the weight is distributed very well across the headband, better than the Sony's imo. All in all, it's a close call and the Sony's are really well done comfort wise. Super light and super cushy pads. Could see a reasonable person going in either direction for the win here. Sound quality: I think the XM5 are pretty close to the Bose 700 and could see folks going either way depending on your signature preferences. Personally think I like the Sony a bit better, just more lively than the more neutral Bose. Both are in the same league though. The M4s are way better sound quality wise plain and simple. They're not in the same league. Heck, they're not even playing in the same sport. Find myself listening to music way more often during the day simply because I enjoy it that much more. This is the reason I'm ultimately sticking with the M4s. And it's not a hard decision. Noise cancelation: Sony XM5 are simply the best. If you're buying headphones to block out the sound of your partner playing annoying tiktok vids, this is the one to get. M4s have pretty good noise canceling too, but the Sony's are way better here imo. Bose sits between the XM5 and the M4s, maybe just a little better than the M4s Mic sound quality: I'm work remotely with multiple meetings throughout the day so I've done extensive testing on all three models. In a nutshell if you don't have any special requirements, all of them do a great job. In quiet conditions I prefer the the M4 a little better than the others, my voice just has more body to it, but again, it's plenty clear using any of these models. In noisy conditions, the Sony XM5 are way better than the rest in isolating your voice and minimizing background noise. Simply incredible! The 700 and M4 handled the background noise a bit differently. My voice is clearer on the M4s in noisy conditions whereas the Bose cancel out more background noise at the cost of sacrificing clarity. When there's lots of noise, the Bose can reduce your voice to the point where it's super difficult to hear what you're saying. The M4s will allow more background noise through, but my voice remains super clear and louder than other sounds coming through. One feature I really like about the M4s, the one and only button they have (making it super easy to find) becomes a mute button during calls, zoom or google meetings. Really enjoy that feature as I could walk around the house and unmute myself if I need to talk. A voice tells you if it's muted or unmuted so you know where you're at. No more flushing the toilet while running out of the room hoping no-one on the meeting heard it. The background noise canceling of the XM5 during calls was so good, it made me really want to keep them. But ultimately good music sound quality is something I'd enjoy more often since I'm not often taking meetings in super noisy conditions. Also the M4s have the mute button I could use if I do find myself in that situation. Summery: If you want incredible noise cancelation while listening to music, taking calls or meetings, the Sony XM5 are the one to get. They are head and shoulders above the competition in this respect. If you wanna be wowed by how amazing your music sounds, renewing your love for music you didn't even know you had, the M4s are for you. These are the main areas where there is substantial difference. Sony and Seinheiser truly impressed me in their respective areas of expertise. Aside from those standout areas, these are all great headsets. Even the Bose 700 is a really solid headset. Unfortunately it wasn't able to differentiate itself when compared to these two titans of industry. Noise canceling is great, just can't touch the Sony's. Sound quality also great, just can't touch the M4s. Arguable the Bose are the slickest looking headset of the bunch though.
