M4AEBT Momentum 4 Wireless Headphones - Black

Absolutely incredible. Mind blowing. By far the most effective active noise reduction. I didn't realize just how noisy my house was until I started using these things. Utter silence. And the sound quality is by far the best I've ever heard in any headphones or headset. Bass is so tight that some drumstrokes feel like someone is physically tapping on the cans themselves. Rumbling or deep bass is also phenomenal. I do really appreciate good sound but I'm not an audiophile and don't have a lot of ten-dollar technical words to throw around so my description might not be all that helpful. Speech or dialogue sounds like actors sitting talking in the room with me. Everything from synth and bass-heavy dance music to grinding, snarling metal has a level of detail and depth that totally new to me and I've been listening to music for over fifty years. The best way I can put it is that the sound quality is so outrageous it's really beyond my ability to fully appreciate. I use these cans for exercise, for watching movies, watching TV, and just listening to and watching music videos on my phone, multiple PCs, and my iPad. The headset pairs with all of them and moves between them with no effort or any issues whatsoever. The battery life is nothing short of phenomenal. I use them every day and have only had to charge them maybe once a week or so. All I can say is that I practically stole them using a combination of gift card and Amazon rewards plus a little cash but for the quality, I'd gladly pay the full price for them.

Honestly the greatest pair of headphones I’ve ever owned. Had them for a few years now and they still hold up just as well today as they did when I purchase them. Super comfy and adjustable if I’m wearing a hat. I don’t use the corded function only Bluetooth but the sound is still perfect. Used them everyday as a mechanic, firefighter, and maintenance technician and dropped multiple times, still holding up just fine. Love the case design, the white wasn’t my best choice as they get dirty easily. But other than that a fantastic pair of headphones. Considering buying another pair soon since mine are getting old.

These headphones audio quality are amazing some of the best headphones I’ve ever owned, 1 small PROBLEM, they aren’t water resistant in the slightest, and I know that’s my problem for not looking into it enough, anyways, I got a little bit too sweaty doing some cardio and it sounded like the left ear blew out completely and now all it plays is a buzzing crackling noise every time I power on the headphones. So if you are buying these for gym/sports use be careful, if you are buying these for audio quality and for my audiofiles out there these are top notch, noise cancelation isn’t the greatest but I’ve definitely had worse, I’ve heard the momentum 5s ANC are better but I wouldn’t know. Anyways to sum it up for audio quality, build quality, comfort, and software they are top notch but that one slightly sweat problem made them only last 3 months because I finally decided to do hard cardio 1 time.

UPDATE - BRICKS IF POWER DRAINS - DO NOT BUY!!! This is an update to my previous review. These are a passable set of headphones evaluated on audio quality. And since I wrote my email below, Sennheiser actually fixed the app to turn off some of the terrible touch features I described in my original review below. But I just replaced my old unit that wore out. But the new units brick if you let the power drain. If the battery fully discharges on these units, you will never be able to get them turned on again. Even worse if you google and chatgpt this, it is a known issue. Do not buy these headphones. It's ridiculous that the manufacturer has these on the market. My research reveals they know about this issue. ----- I have owned at least five pairs of Sennheiser headphones, three in this very line, and it's hard to understand how they get worse instead of better. I ignored the questionable reviews on here thinking people were being overly fussy about audio expectations, but the problems with this product are varied and not what you would expect. Whereas many bad products don't live up to your expectations, these headphones work so poorly and cause so many problems that you can expect them to rob your time and continually cause you aggravation and issues on a daily basis. The fact that I am even taking time out from my busy schedule to write a review speaks to just how terrible these things are: - Audio quality is decent and about what you would expect in a mid-range set of headphones (this is not an audiophile product). I do notice that there is no bass boost feature that previous versions had that I liked. The decrease in audio quality is disappointing, but I probably could have lived with it, as I think the intended application for these phones is being out and about. But that's just where the issues begin... - The real problem with this Momentum line is there is no continuity and improvement with the features. I would expect the designers to be learning from their mistakes and adding improvements with each generation. Instead, each new version has a wildly different approach, and in the case of this model, they have decided to introduce tons of "smart" features, because isn't that just the thing to do these days, regardless of whether it does anything "smart" to enhance the experience. To be clear, I am referring to the array of "automated" features that I detail below. - Most features are automatic and cannot be turned on and off. They claim they can. There is a bluetooth phone app. But the things you can control there are limited. And what can be controlled is worthless, because the headphone constantly lose the connection and settings with the app, so there is no persistence, and you will have to go in again and again to control things that can be only controlled and only in the app. - There is a touch-sensitive pad on the outside of the right headphone that sounds like a great idea, but is a curse to plague your every move. The intended functions of changing volume or tracks, etc. is pretty inconsistent. But anything that touches the pad is going to do something random. If it's raining, your hat touches it, your hair brushes it, you pull your hoodie up, anything is going to do random things to the controls to interrupt your experience. - Even worse are the features apparently intended to anticipate what you want based on movements. If you slip the headphone off one ear for example, it stops the music. Sometimes when you put it back over the ear, it starts again - most of the time not. If you turn your head left or right, or turn around to look backward (which I often do working with these things on) it will pause or stop the music. Sometimes when you turn your head back, it turns on again - most of the time not. - The single manual button on them controls the few key functions (on, off, bluetooth pairing). It is controlled by the time you hold the button, and does not work consistently. So you might be playing around with it for 30 seconds or a minute trying to get them on or off, instead of just flipping a switch in an instant. In summary, nothing works as it should, and instead of putting them on and falling into a flow or work or running, or whatever you want to do, these things are going to constantly start and stop, interrupting and frustrating you to no end, the whole time you are trying to use them. I despise them. Why not just keep it simple and build on the quality foundations that this product could have. The people who designed these things should be put in design prison. I have had my share of disappointing products over the years, but I can't think of another one that keeps doling out the punishment or disappointment in quite the same special way that this abysmal product does.

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): 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. I enjoy using them. It’s not complicated not one bit in my personal opinion and experience but sometimes the functionality is not very accurate. 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. I don’t know how to intelligently break down frequencies so you’ll have to find an expert who hear 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 👌🏾 The lows, mids, and highs sound really great in my opinion. 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. 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.

5 stars to me. 4 stars all around for the average consumer due to issues I believe others will find a problem with but I have found some workarounds for I will start off with the flaws (unfortunately it has em) from my experience and some solutions. They are mostly features based. I'll also address confusions and "negative" experiences as there are reviews where clearly it's the people and not the headphones that are the problem yet they are giving this a worse impression that it should have. And lastly praise what it has going well for it Also, I will highly suggest downloading the new app version called smart control PLUS and install any firmware updates. Then go adjust settings or it will have some annoyances. Flaws On-head detection: this causes most of the headaches. For those that like to free up an ear to listen to someone talk better - make a habit of freeing your left ear and not the right. There is a sensor to detect your ear and it is only INSIDE the right earcup. It makes a double click noise when it detects and stops detecting your ear. Unfortunately it makes a similar sound for both which is a huge flaw as you might not know if it is detecting or not sometimes. This will trigger the auto off feature if it doesn't detect you while you're listening to music. It usually pauses from the headset, but there is a possibility it can be ignored by an app and continue playing so when you put it back on you might not even know if it detected you. Another possibility is you made the mistake of pressing play from the app itself when it stops detecting you thus eventually triggering the sleep feature. You can disable auto off but I personally put it in 1 hour just in case as I would have likely readjusted my headset by that point and reset it. This goes into the next feature: auto play. It's perfectly fine on mobile but on PC it can be a nightmare as you could be listening to music, you adjust your right earcup so it pauses and when you put it back on, it might play some other video like youtube in an open browser; it depends on the programs that behave to bluetooth pause/play. So don't have so many open video/audio programs in the background. Also for those with long hair, autoplay can struggle to detect if it completely covers your right ear (some people start to think it stopped working). Overall, I just disabled autoplay while keeping auto-off enabled as I mainly use the M4 on PC, but again, it seems to work really well on mobile. Plus of course if any of these aren't necessary to you, you can simply disable it as a whole for an old fashioned headphone experience to avoid annoyances but I have gotten used to it at this point that I rarely have issues [Update: I just learned on May 2025 that as of the new firmware 2.13.42 it reads "Improved auto-off behavior reducing unexpected behavior during calls or streaming due to misdetection in smart pause sensor", so perhaps this section might become untrue with less flaws down the road thus hopefully improving user experience] Multi- point connection: It can and will connect to two devices that have bluetooth active after they have been paired. There are individuals that pair their headphones to everything and might experience a random connection. Unfortunately no disabling this so you have to be precise with what you want to connect this with. I only paired this to PC and mobile so it doesn't attempt to connect to anything else but in the app you can click to what else in the list want to connect to (or delete). When it detects multiple signals it will prioritize connecting to what you last used, it seems. Not an issue for me. Also, it will ALWAYS prioritize audio for the first connection of the two which will usually be the phone. This is important. If it connects to my phone first, well lets say Im on the PC listening to music, once your phone makes any kind of sound, your audio will switch to it and interrupt the music, then resume playing your PC's music. Because of this, disable useless sounds like the lock screen opening sounds because that will trigger a switch (not sure about typing sounds). I have sound on for notifications to get my attention for the phone but if that is an annoyance I would try connecting other devices (like PC) as your main device first and then phone second. That way, it will ONLY play audio on the main device (PC) in spite of your phone making noises or playing audio. I tend to disable phone bluetooth, so it isn't an issue for me what connects first anyways. Now, this is a major flaw which may have been addressed in the new firmware update and app but I have not fully tested yet so this is based on months old experience. Last flaw with this. Do not have constant audio playing on -BOTH- devices because it will cause some static to what you are listening to. No idea why this happens but sometimes the music sounds glitchy and I realize it's because my PC is playing music alongside my phone. All it takes is not having something like music playing on the second device and it gets clean. Reboot: it can be done on the power button after holding for over 15 seconds. Be careful NOT to do this if it is not your intention. I have a friend who accidentally did this High resolution: app is glitched if you try to do personalized sound after enabling high resolution. It will ask you to disable high resolution before proceeding. All you have to do is go to standard mode, make your sound profile, then go back and enable High Resolution. Confusions: ANC: some people complain you can't turn off ANC. You sort of can. Old app, on the ANC slide, you put the slider in the middle. Most importantly, the new version of the app now allows to turn off ANC and might possibly increase your battery life. Oh, and some people remark of ANC randomly activating when outside. That is the wind noise reduction activating during air blowing directly to your mics. You can turn it off in ANC settings (you can also adjust transparency during phone calls there) but trust me that you don't want to hear wind transmitted into a headset Auto-answer calls: complaints on this but another reason you need the app to disable it if you don't want it. Aut-connect: some complain that if it moves it will auto connect or cause confusion when they don't know why their bluetooth loud speakers stopped working until they realize the headphones are connected. I personally love auto connect and has never been an issue. I put my headphones away where it won't move at all and once I grab it, boom, just straightforward and smooth connection grab and go. This is a feature of auto off so if you don't want it to be doing this you can either disable auto off (more like sleep) or turn off the headphones directly from the power button (which means you will also have to turn it back on with the button). I don't think of it as a flaw to be honest Discord/meeting calls: This is a big one. There are people mentioning how when they get on discord, their music and game sounds muffled. That is its hands free activating because it believes you are in a call. It prioritizes the call once it is activating its mic. You may have noticed it on your phone before too with music getting muffled. Problem is these then get compared directly to a gaming headset. Most gaming headsets have a usb dongle. Those dongles are designed to give both high quality low latency audio and mic signals at the same time. These? They are bluetooth headsets not specifically designed for gaming but rather for high quality audio. This is not a major fault of the headset. There exists a workaround for this but you will have to disable handsfree and rely on a different mic (which can be a far superior option anyways). To do this - on windows 11, go to settings. Click "bluetooth & devices". Then click on "view more devices" up top to go to a drop down list of devices. Scroll all the way down until you find "more devices and printer settings". Find the M4 headset, right click and go to properties. Click on the hardware tab. On this list, look for Name "Momentum 4 Hands-Free" that is under Type "Sound, Video...". Click once on it then click on properties below. In properties, General tab, click on the blue and yellow shield that says Change Settings. Then go to the Driver tab and Click Disable Driver. Reboot PC. Can be undone in similar method. At this point it has no headset mic active ~specifically~ on the PC (phone should be unaffected) so audio will be clear but now an external mic will be needed. Experiences: Connectivity: people say they have connectivity issues but thankfully it is very rare for me. It has a good distance to it too. I keep up to date with everything on my phone Touchpad: some say it is very sensitive. It is certainly more sensitive than usual but there are exaggerations to it. My hair does not trigger it. Turning my head does not trigger it. I don't trigger it with a hoodie on. I don't wear beanies over it (why would you?) so I cant say anything there. Stretching my arms above my head might trigger and laying my head on the right side might make it think you want to change volume or transparency. But some of these reviews are funny. They are not rated to be water resistant at all (like most headsets) so if rain drops trigger it, actually no, WHY DO YOU EVEN HAVE IT IN THE RAIN? App: the app is fine minus the glitch [refer to High Resolution in Flaws] and has only been improving bit by bit. There's now also a new version which requires a new download that will likely be getting more of a focus on Durability: it is plastic which makes it lighter but thankfully I have not broken anything. I have bumped it into things, dropped it once. I try to treat is as glass so these are rare occurrences. I would not work out in these due to the fact they are not designed to deal with liquid. If problems occur because you work out in these, well that's your fault, but there exist rubber sweat covers to put over the padding to help out a bit. The Sennheisers Momentum 4/Sport earbuds I believe have water resistance and might be worth a look instead if you need a true gym companion Strengths Audio quality: right out of the box, they are great. It has a neutral sound profile while having some attention to bass. There are presets in the app that are decent and it really does not need a bass booster but it exists. To be honest, I would skip everything and go straight for the sound personalization feature in the app. It's very simple to adjust, uses mostly sliders while you listen to audio. And once you are done it will create a setting that somehow manages to be far superior than what's already available in the app. It just cleans up the sound so much more to your liking; the difference is bewildering. Ever since that point, I have not listened to music the same. Just when I thought I was getting bored of music, these revived that love to want to listen to everything again and also motivated me to listen to things I never did before. There is literally pre-Sennheiser and during-Sennheiser eras to me now and am curious to their wired headsets. One thing that will become super noticeable is its soundstage. It spreads the instruments to a degree where you can notice more of everything. Albeit, this can be discombobulating and bassheads might not like the lack of sharp precision but this isn't meant to be your average linear listening experience (the Accentum Plus offers this at a much lower price). To give an example: What is Life by George Harrison. I might prefer it on the more linear style I am used to but these can separate things to the point where it is also directional and you can feel like you are standing at a concert and George is directly in the middle of it all in front of you so it feels more real- similar to as if you are becoming conscious of your own breathing. And in midst of all the chaos, you can still clearly hear George's voice and you notice ALL of the instruments more. It first gave me goosebumps how much it changed the song. Some songs are designed to be "linear" which could possibly affect emotional type of songs negatively but from a musical perspective, my goodness it is incredible. Now I just go back to see what music I am used to that changes with these (hint: a lot). Electronic/hip-hop music perhaps is the exception but this gives such clarity to detail that it is still a great listen- one thing is for sure these headsets love when there is a band setup (Bjork, the Roots, Gorillaz, etc). Sound quality is the biggest reason you go for these. Comfort: I can go on for a while without my ears hurting or anything. Also these don't heat up much and has proper adjustability for bigger heads Look: I have the black with copper ring and they are absolutely gorgeous. I question the longevity of the cloth on the headstrap but it makes it more beautiful than it has any business being for a plastic headset Features: ANC is better than I expected. It does its job, and though it might not lead in this category, the differences are so small compared to the competition. Also drowned out what I needed it to during plane trips. And hearthrough, although I have had better, they will more than suffice to the point where I rarely have any issues hearing people. The fact that it is good at both of these is amazing for value. Battery: they can go up to nearly 60 hours, especially in standard mode. Not an exaggeration. I can go days without charging them. For this quality of headset, I don't think much of the competition comes close to this. In fact this is the mind blowing part because most other bluetooth headsets don't sound anywhere as good as these and they have half the battery life if not worse. No fears when travelling that it will die on me. In fact, it lasted me an entire week's trip Surprises Gaming: it has low enough latency. Combine that with that very clean audio and surprising directional audio this already has and wow, it performs quite well. I can actually spot details better and sometimes extra details I wasn't aware like I remember distinctly many months ago when I played Paladins, not only was I able to hear behind a wall slightly above me, but I realized it was subtle high heel sounds. I am not saying this will replace top of the line gaming headsets like steel series but if you have these and not a gaming headset, these will more than suffice. Charging: I was already enamored by the battery life but the fact is, it handles charging nearly as well. You can get hours worth per 10 minutes of charging and around an hour and a half or so it will be fully charged. That may not sound great but half of that will net you 30 hours of life which is STILL more than the competition. And the other surprise was that I accidentally discovered on the PC that you can still use it while charging - it simply appears as a different sound output you have to switch to. I thought it was weird how multiple momentum 4's appeared but when I clicked the other output, music started booming through it again. I was shocked. It already has a super long battery life with quick charging. It doesn't need it yet it has it. I have never had a headset that allows that with USB-C. Sennheiser were practically showing off at this point. So I would get a super long cable to make this comfortable during charging if you think this is a feature you will be using These are already the greatest -bluetooth- headsets I have ever owned under the $500 mark. I have tried out direct competitors Airpods Max (best hearthrough and good clean quality) and Sony Xm5's (amazing features and stylish) but the M4 felt like a no brainer. The max have poor battery life (under 20 hours) meanwhile these can reach close to triple that. The XM5's are light and so smooth with their features and touchpad (I loved speak to chat) but their fragility comes into question as they are notorious for the hinges breaking no matter how good you take care of them while the M4's mostly have earpads wearing down (easily replaceable). Meanwhile, guess what? The M4's imo sound better than both of them, are more comfortable than both, and can be found MUCH cheaper than both as I have seen it as low as $190. Even if, say, the Bowers & Wilkins PX8 might have slightly better audio and a better build, it's not a major difference so it is imo horrifically overpriced while this just has much higher value after sales and is an easier recommendation Overall, it absolutely bothers me just how overrated the other headsets on Amazon usually are meanwhile these get a bad impression. If you are a fan of music and you want to improve that experience with the bluetooth format at great affordability, it doesn't get better than these

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.

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.

Dit is de beste draadloze hoofdtelefoon die ik ooit gehoord heb. Schitterend geluid en comfortabel draagcomfort.

Sempre tive vontade de ter um fone sennheiser original, e este importado da china (afinal todos são fabricados lá na asia) é original e a meu ver perfeito! O isolamento de ruidos é satisfatorio, não preciso de muito. Seu audio é maravilhoso, e usando o app de androide tem diversas equalizações, mas eu deixei em NEUTRAL, pra mim foi a que mais agradou! Fui assistir o filme TRON em 4k audio 5.1 no pc e no celular pelo app do stremio e realmente a qualidade é fenomenal! Audio: Cristalino, e olha que ja tive fone samsung buds e esse é melhor. Bateria: JOGO bastante no CELULAR (bluetooth) e ouço videos no COMPUTADOR e realmente o fone dura as 60h, mesmo com o cancelamento de ruidos ativo. Sua espuma é macia e não aperta demais, nao doi a cabeça, não cai da cabeça mesmo se abaixando pra pegar algo. Qualidade: é plastico, mas de excelente qualidade, e tem tecido na alça do fone, agradável. Sua espuma é revestida em courino, mas vai durar mais de 1 ano com certeza, e depois só comprar uma de veludo e repor no lugar, tem algumas à venda aqui mesmo na amazon brasil. Comprei um transmissor aptx da UGREEN usb-C e é compatível com o momentum 4, funciona maravilhosamente, em filmes DOLBY fica xuxu beleza (gíria brasileira para ótimo). Enfim, agradeço a amazon e ao vendedor addventure pelo excelente produto e entrega rápida (exatamente 1 mês após a compra, mês de dezembro e moro no NORTE do BRASIL)

Da tempo ormai al pc sfrutto le cuffie, soprattutto nelle ore notturne durante il gioco, per non disturbare ed avere una maggiore immersività. Avendo a disposizione un DAC audio di qualità utilizzavo dei modelli a filo, con l'unica pecca che non abbia un selettore dedicato per switchare fra casse e cuffie, il che rendeva un po' scomodo il passaggio. Da quando però ho riconfigurato la mia postazione, il cavo diventa scomodo perchè devo rimuoverlo tutte le volte dopo l'utilizzo o mette disordine sulla scrivania e devo raccoglierlo in un cassetto. Oltretutto dopo l'ultimo modello con i padiglioni rovinati dal tempo avevo preso un paio di Sennheiser HD599 delle quali ho letto bene ma ho riscontrato una qualità bassissima rispetto ad altre di pari costo e che ho prontamente messo in un cassetto e li ci sono rimaste. Ho optato dunque per un modello wireless con cancellazione del rumore e specifiche di livello elevato sulla comunicazione bluetooth. Purtroppo dopo un aggiornamento windows il bluetooth non ha più funzionato in modo efficace, principalmente nella sua funzione comodissima di commutazione del segnale una volta accese le cuffie, dovendo sempre trafficare nelle impostazioni per utilizzarle, cosa ancora più scomoda del filo di prima. Peggio ancora ha inibito la cancellazione dei rumori, la quale si disattiva sempre dopo 3 secondi dall'avvio e senza alcun verso di farla funzionare. Ho provato a risolvere con aggiornamenti e programmi audio, ma la situazione è solo peggiorata, rendendo le cuffie inutili. Ho così deciso di investire un po' di più per questo modello di alto livello con il suo dongle usb per la massima qualità e la situazione è cambiata notevolmente. Innanzitutto sono confortevoli indossate, padiglioni grandi ed archetto morbido. Non si possono ripiegare come altre concorrenti, ma vengono vendute con la loro custodia rigida nella quale si ripongono perfettamente. In dotazione arrivano un paio di cavi e connettori (possono essere usate via cavo) e manuali vari, il tutto nella custodia che funge anche da auto-spegnimento delle cuffie quando riposte, cosa comodissima perchè basta estrarle e si accendono immediatamente connettendosi in un istante. La qualità del suono è ottima, io sfrutto il dongle usb btd600 per i problemi prima elencati con il bluetooth del pc e ogni abbinamento è semplice così come la commutazione dell'audio. I brani in qualità flac e i video con codec ad alta qualità si sentono notevolmente meglio rispetto alle HD599, veramente un altro mondo. Peccato per quel modello in quanto sono una pecca rispetto altri modelli acquistati in precedenza sempre del marchio di cui sono stato pienamente soddisfatto. La cancellazione dei rumori è molto efficace, funziona bene, se pur non è totale e qualcosa di lieve passa comunque (credo che il top si possa solo avere con auricolari in-ear per l'isolamento che intrinsecamente forniscono), ma molto alta e comunque soddisfacente. Utilizzandole principalmente in casa è sufficiente ad isolare dai rumori di aspirapolvere o tv delle altre stanze. Il padiglione destro consente i vari comandi multi-touch semplici ed efficaci, senza dover cercare con le dita microtasti andando a tatto. La ricarica è tramite usbc, veloce e consente ore ed ore di ascolto, quasi da dimenticarsi che siano a batteria! Ovviamente l'ANC consumerà maggiormente energia, ma parliamo comunque di decine di ore senza problemi. Personalmente non le indosso per tante ore consecutive, a parte occasioni sporadiche, ma le trovo molto comode e per nulla pesanti, non fanno sudare le orecchie e in generale le trovo molto confortevoli. Dopo le varie disavventure con il bluetooth del pc, sono quasi contento di averle avute perchè mi hanno convinto a prendere questo modello che pienamente mi soddisfa e sto godendo di una qualità audio eccellente. Connesse al mio mac o all'iPhone funzionano perfettamente (ma anche le precedenti, il problema era solo legato a windows), sullo smartphone poi hanno l'app dedicata per impostare e regolare al meglio come più ci piacciono i suoni. Molto comoda poi la possibilità di un doppio abbinamento bluetooth così da non dover sempre fare la connessione ogni volta che si cambia dispositivo. In definitiva sono pienamente soddisfatto del prodotto, non le ho confrontate con le concorrenti Sony XM5 o addirittura XM6, ma al momento dell'acquisto costavano di più e dalle recensioni si equiparavano con piccole differenze a favore di uno o dell'altro modello, per cui sono rimasto fedele al marchio nonostante lo scivolone di quelle cablate. Ovviamente per il top della qualità audiofila ci sono modelli molto più specifici e costosi, tutti via cavo, ma alla versatilità e comodità di queste non rinuncerei mai, soprattutto utilizzate con tv e console, pc, smartphone, passando da uno all'altro in un attimo.

Great headphones with spectacular and customisable sound. Battery lasts a long while and the comfort of the pads, over long periods, is good. ANC is customisable and works well as does transparency mode. Best price out of the big hitters and well worth it
