Fit. Here's the deal, I have some big ears, with 3/4" gauges. With my gauges in, I do get some pain in my neck. I have pain issues, so this was no surprise, nor is it a fault of the design. My ears fit fairly comfortably inside the cups to help lock out sound, minus the gauges. The polypropylene(?) material is quite soft and moldable, making wearing them for an hour or more easy and comfortable.
I have a kinda funny shaped head (IMO. But I'm highly critical of myself and the world), but these look really slick placed on my dome. I got black, because black goes with everything, and I don't wear color. Look and fit much better than cans I've owned in the past.
Noise cancelation. The ANC is good, but not great. I found the ANC on the WF's more thorough, which is a bit odd considering they're earbuds. However, they do form a more legit seal in the ear canal, so it could be that. There is some "hissing", but part of that is also my tinnitus. I find that there seems to be some slight hissing even with the ANC off. It's akin to being in a super silent room, and you hear the "hissing" from an AV system with it powered on, but with no sound. I've not flown with them yet (Which is a huge reason why I got these), but I assume they'll be just fine for passenger and engine noise.
Sound quality. So, I'm pre-burn in on the drivers. There is usually 100 hours or so of burn in on every new speaker/driver on the planet, and these are no different (I have not researched this in actuality. I was in AV for several years, and have some knowledge). But, so far, they sound very pleasant and accurate. I opted for an EQ setting (Excited) just to bring out certain details in the instrumental/electronic music I'm currently listening to. You can hear the trilling of the tongue on a flute, and the fingers against guitar strings. The detail is fairly rich, while maintaining a fairly neutral overall tone. The sounds seem to be reproduced fairly accurately and are fantastic for instrumenal music.
For the price I paid, these are great. However, for the normal asking price of around $350, I expect the soundstage and sound field to be superior to what it is. It is evident that you are hearing music played through 2 speakers often times, instead of an amalgamation of speakers 180 degrees in front of you, or listening to a live performance where the sound comes from everywhere. Think of this as 3D sound if you will, similar to Dolby Atmos. I understand they have the real 3d audio whatever, but right out of the box, they should be fully immersive.
Battery life/Bluetooth. Battery life seems to be ok with ANC on. I use ANC exclusively because I like to drown out reality while listening, especially during meditation. I suspect you could easily get 8 hours of consistent listening with ANC on before needing to recharge, which is plenty for half the flights on this side of the world (North America). What else can I say about battery life??
Bluetooth connectivity is very strong and nearly instant. I can walk from my apartment to my neighbors apartment with my phone in my apartment and still have unbroken connectivity. THAT is freakin awesome.
Overall, I'm very pleased with these cans, especially for the price I got them at. At the normal asking price, I'd recommend checking out the XM5's since their so similarly priced. If you're looking for a solid set of cans, and these are on sale, don't mess around, just buy them. You won't be disappointed.
Pros
Excellent noise cancelling
Very good sound quality for all Bluetooth profiles (Listening to music, phone/video calls)
Battery life
Excellent Bluetooth range
Automatic voice detection to pause music and enter transparency mode
Cons
Touch controls are simply awful!
Dual Bluetooth device support
Constant beeps and noise cancelling turned off especially with “Detection of Actions” enabled
Voice detection for stopping music and going into a transparency mode responds to almost any sound you make. A large breath, grunt, anything will trigger this feature.
Rubs on the “helix” outer part of the ear on the left ear
Somewhat complex set up process
Overall these are really excellent Bluetooth headphones. The noise cancellation is absolutely excellent. This is probably the best noise-cancelling headphone available. The Bluetooth range is also exceptional. Audio quality for music is also very good, and I expect most people will find them to be excellent. Phone/video call audio is also good receiving, and acceptable for the microphone. They have long battery life and charge quickly. They are relatively comfortable as well. The touch user controls are simply dreadful. There are many other features with a range of benefit.
Comfort:
They seem comfortable, and the ear pads are soft and plush. However after several hours the outside of my ears start to hurt from rubbing on the insides of the headphones (the area called helix on top of the ear rubs on the inside of the left ear around optical sensor area.) If at sometime we resume taking long international flights this could be an even larger issue.
They are still comfortable though when wearing them with glasses. They ear pads are pliant enough to continue to make a good seal without painfully pushing them into your head.
Bluetooth, Pairing, Multiple devices:
These support 2 Bluetooth devices to be connected simultaneously. The Bose QC35 has had this feature for some time. I initially paired my iPhone X with the headphones. I then added a MacBook Pro from within the Connect app. I was then able to play music from the MacBook. I went back to the iPhone and tried to play something. It didn’t immediately play. In fact, it is rather finicky. Sometimes starting something with audio on the iPhone will cause audio to switch. Mostly it doesn’t if something is playing already on one device. Stopping the audio, waiting, and then starting the audio on the phone is a bit more reliable. Even if the source on one device is paused and not playing it may not switch back.
This is a bit problematic though since the iPhone still thinks it is connected to a Bluetooth headphone, so the audio is still routed to the Sony WH-1000MX4, but isn’t played – so it goes no where. This works far more seamlessly on the Bose QC35. I actually found myself disabling this feature half the time.
While the WH-1000MX4 does have voice announcements, it doesn’t speak the name of the device. It will say “Bluetooth device 1 connected,” whereas the Bose QC35 will speak “Joe’s iPhone.” Even more confusing is that device 1 and device 2 doesn’t always refer to the same device. Sometimes my iPhone is device 1 and other times it is device 2. The only way to really know is to go into the app where it will identify the device associated with device 1 and device 2.
I added a 3rd Bluetooth device, again from the app. This works, but will disconnect one of the 2 already connected devices. It works pretty much like most Bluetooth devices. You disconnect at least one of the currently connected devices and then connect the new device. You can have multiple devices paired, but a maximum of 2 devices currently connected. You can see the list of devices within the Connect app.
Bluetooth range is excellent. It would easily stay connected when going from one area of a reasonably large house to another. The range exceeds any other Bluetooth headphones.
Sound Quality:
Sound quality has to be the most subjective area to evaluate, yet one of the most important. Most people will find these really very good to excellent. For most these may well be the best sounding headphones they have ever had. Those more critical may find a few areas where they lack, but still they are excellent for noise cancelling headphones. Sound quality is probably one of the best aspects of these headphones.
The sound quality when listening to high quality content was very enjoyable. Overall they are fairly well balanced, albeit a bit heavy on the low end, but not boomy or with obvious peaks in the response. More so they sound “warm.” The bass is noticeable, and quite deep. You will clearly hear the thump of a drum, but still somewhat tight. The deep bass on some of the Billie Eilish tracks is impressive. The bass is not so excessive though that it drowns out mid or high frequencies. Music sounds good with individual instruments clearly identified. Male and female vocals sound good and natural.
The deep warm bass works well for movies and similar entertainment. These will likely work quite well for watching airplane entertainment. High frequencies are clear, and more smooth than harsh. They are balanced overall with a bit more low frequency emphasis that shifts the balance a bit.
The iPhone app does have equalization settings, so it is possible to adjust to your personal preferences. I reviewed these set at flat, default setting.
If one is going to compare these to audiophile headphones they will clearly notice differences. They will not replace examples of the best open or closed back audiophile headphones. They simply lack the detail, imaging and placement that those headphones present when paired with a quality DAC and headphone amplifier. That really isn’t a fair comparison though as these are noise cancelling Bluetooth headphones and they do a great job at that.
I did listen through both Bluetooth with the AAC codec and wired with a quality external DAC while listening to high resolution content streamed from Tidal through a Master Quality Authenticated DAC. They do sound better with the same content played through a wired DAC than Bluetooth. The difference wasn’t as much was expected. Sony did a good job with Bluetooth. I also tried listening to them with the power off, as plain wired headphones. They didn’t sound that different, which is rather a good thing. The same experiment with Bose QC35s will have a totally different sound. Bose relies extensively on equalization to get their otherwise somewhat poor sounding headphones to sound good. Sony starts out with decent sounding drivers.
I have not tried using the LDAC hi-resolution Bluetooth codec yet. This isn’t as easy as it would seem to use on either iOS or MacOS. You can’t simply use a high-resolution source to use it. You need to download and install the Sony Music Center app, then load the high-resolution content into that app to play. I’m not sure how to get it to work with a Mac at all. The better codec should sound better. To be fair, at least part of the problem is Apple in this case.
I did try the DSEE Extreme feature. This supposedly improves the sound quality of low bit rate compressed content. I listened to some low bit rate MP3 files, and some standard streaming services, such as Amazon Prime music. It sounded different, I’m not sure I would say it sounded better. At least what I noticed was a boost in high frequencies. It made some of the squashed high frequency details more noticeable, but they still sounded highly compressed, and to some extent the compression artifacts became more noticeable. This may well be a personal choice, and likely varies over content, level of compression, and codecs used. The bottom line is that you really need to start with quality content.
The 360 Reality Audio was a disappointment. I tried playing a variety of tracks in 360 Reality Audio on Tidal. I did this using the Tidal app on both iPhone and a Mac. I did link the Tidal app with the Sony app as part of the initial setup. I did notice a wider sound stage. It wasn’t like demos in a movie theater for Dolby Atmos or anything that dramatic. There was some front/rear placement depth. It was interesting to play with for a while. What I found though is that it just sounded strange. I played some of the same tracks on Tidal HiFi or MQA and to me they sounded much better, much more musical. Call me a purist, audiophile, or whatever, but I found the highly processed audio more annoying than enjoyable. It doesn’t replace the stereo imaging or placement that superb headphones can present as described above. Honestly overall these sound good enough without these audio tricks. Perhaps if there were some movie encoded with 360 Audio it would be better to enjoy special effects and less about musicality. It seems more of a gimmick than musical. By far the best quality was the same song in Master Quality on Tidal with an external DAC and the 3.5mm wired cable.
Phone calls
The audio quality on phone and video calls has been excellent on the receiving side and is about as good as Bluetooth HFP profile gets. it is excellent for conversations. With the excellent noise cancellation these are excellent for long video calls. They will likely continue to be great for those forced to endure a noisy open office environment, or need to make phone calls in a noisy area such as an airport or train station.
Phone call microphone:
Overall I’ve had only a few complaints from those that I’ve in meetings or on calls with. Most people said I sounded fine. I was on one phone call with my iPhone and the person had difficulty understanding me and could hear me fine when I switched to the iPhone. They said I sounded “far away.” On a video call I had some people refer to the sound as “bubbly.” After switching to AirPod Pros and the sound improved.
They seem to isolate ambient noise reasonably well, although I haven’t had extreme cases to try during working from home due to COVID-19. This is one area where Bose QC35 were awful. I don’t know if they match AirPod Pro for microphone beam forming, but so far they seem fine. These work for phone and video calls, but aren’t great.
Noise cancellation
These are fantastic at noise cancellation. I haven’t been on an airplane with them, the real test, but these seem significantly better than the already excellent Bose QC35. At least around the house they block out the low frequency sounds that noise-cancelling headphones are best at. Around the house even a Ninja blender was mostly attenuated while I was on a conference call. My neighbor’s air conditioner that still can be heard with the Bose QC35 and AirPod Pros is completely gone with these. I was even using a really loud flooring saw and used these. I did still hear the saw, but not very loud, and I could still enjoy music while sawing flooring! Family talking is mostly gone during conference calls and entirely when playing music. I expect that these would be great in an open office environment or an airplane. Bose QC35 were the best I had used prior to these, and the Bose don’t work nearly as well, especially for voice. They have much better noise cancellation than Apple Air Pod Pro buds too. If your main reason for looking for headphones is noise cancellation, these are what you buy.
One annoyance I had with the Bose QC35 headphones is if I wore glasses the sidepieces would create an acoustic leak and let some noise in. They still work, but especially on an airplane you would hear more air noise. I haven’t tried them on an airplane yet due to covid, but so far I don’t notice nearly as much difference as I did with the Bose with glasses.
Battery:
Sony claims 20 hours of battery life without defining what mode. Other headphones sometimes have decreased battery life with HFP (phone calls). These definitely exceed the rated battery life. With the first charge they lasted almost a week of varied use. I used them for a multi-day virtual conference, and other meetings (combination of HFP and A2DP) for over 14 hours, and they still had 60% charge. Sony doesn’t specify any longer battery life with the wired cable. On the Bose I would plug the cable in when I would go to sleep on international flights, and Bose quoted 40 hours like that, so 20 hours isn’t fantastic. It is more than enough though. It will get you through the longest flight plus some other use. Almost any other use it should be more than enough. I used them over 10 hours straight one day and they were still around 70% charged.
Charging:
These charge with a USB-C connector. They come with a very short (about 6”) USB-A to C cable but no power supply. They charge relatively quickly (less than an hour from 20%, but I didn’t time it). You will need around a 10W power supply to get the fastest charging. I monitored the charge current from 20% capacity. They started at 0.44A or roughly 2.2W, which seemed reasonable for headphones. Then they jumped to 1.32A or about 6.66W, then to the maximum I saw was 1.8A or about 9 W! It is surprising that Sony pushed that much power into a headphone! The actually battery capacity has to be pretty large, so it apparently does use quite a bit of power. In most cases this is of no issue, they charge up quick. It can be an issue is if you are stuck trying to charge them in an airport or airplane port. They will also suck a lot out of a battery pack.
User interface:
This is the worst aspect of these headphones. The touch controls are simply dreadful, almost unusable. Simple buttons would have been much better. Even with practice it is almost impossible to master the gestures to go forward, backward, start/stop, and change the volume. Either it doesn’t register the touch, or it does the wrong thing. You try and turn the volume down and track changes. To be fair, they do have a volume control. The Air Pods Pro don’t and that is really annoying. Even with practice controls don’t work right.
Some guidance: to change the volume, especially lower it, swipe down on the right ear as if you are petting it. Just swiping as if using a smartphone touch screen won’t work right. Swipe down from above the top just like petting it, and then it might change the volume. Changing tracks is even harder, and only seems to happen when trying to change the volume. Hitting the start stop button doesn’t seem to work, except of course when you try to adjust the headphone on your head and then it stops what you were listening to, and would likely hang up a call – be careful of that. I end up using controls on my phone or computer most times. Simple buttons would have been SO much better.
Voice assistant:
Setting up Alexa is not all that easy. Assuming the headphones are already set for Alexa, you already have the Alexa app installed and set up, and the headphones are already paired to the phone you still need to add the WH1000MX4 to Alexa. This takes going to the Alexa app, and adding the device. It will then want to pair with Bluetooth. I put the WH1000MX4 into pairing mode by using the almost hidden mode of holding the power button (rather than the app). It then showed it failed to connect, but it actually seemed to pair on the second attempt. If you were successful you will have a second pairing of the device as LE_-WH1000XM4, for a second Bluetooth Low Energy pairing.
Then Alexa did work hands free (if enabled in the Alexa app). You could just say Alexa and it worked. You could ask Alexa what ever you normally would. It seemed to actually work better than the Echo Auto that also relies on the app. The response audio always has the first syllable of cut off though. This works fine for querying Alexa, or invoking Alexa content. It does NOT work for controlling other functions on the phone, even changing the volume. Telling Alexa to play won’t resume what was playing on the phone, it will resume what the Alexa app used last it seems. This may be iPhone limitations, but I will likely switch to Siri and see if that works better. It would be great if you could have all of them and just invoke the desired one with the appropriate wake word (Alexa, Hey Siri, OK Google). I haven’t tried other voice assistants with these yet.
The automatic speak to chat feature is both great and annoying. At least with the sensitivity set to automatic it will detect voice quite well and stop the content you may be listening to, and allow ambient sound to be heard. This, when desired is far more convenient than Air Pods Pro where you have to hold be button for a few seconds to go into transparency mode. While you still can’t hear what someone says to you, at least when you reply to them, it immediately lets you hear them, and doesn’t take the seconds the Air Pods do. With AirPods you also need 2 actions to stop music and enter transparency mode. This mostly works. In the automatic mode it doesn’t need to actually be voice that triggers it. Anything like a grunt, large breath, anything it seems will trigger it. The slightest grunt or sound and they stopped the music and went into ambient mode. There is a low sensitivity mode that I haven’t tried yet. You will find this feature to be a love/hate relationship after a while. Even with the “Focus on Voice” feature enabled this still seems to be overly sensitive.
Another feature is adaptive sound control. This is supposed to optimize the sound based on location, and detection of actions. This is likely useful when changing between an office, train station, etc. I haven’t evaluated that during a pandemic.
As for automatic detection of actions, that can be very annoying. It was fine when sitting in one place. Initially I didn’t know why EVERY time I bent down the headphones would beep and go out of noise cancelling mode. Then resume playing normally. This is apparently the notification for detection of actions. This can be disabled in the app. If someone were to use these headphones in a gym or exercising this would be annoying as well. (Note: These are NOT sport headphones!)
App
The app is essential to setting up, using, adjusting, and updating the headphones. Sony even uses the app for pairing with the iPhone, which is unusual. The app allows configuring the many options available, equalization and more. You also use the app to optimize the headphones for the shape of your ears by taking a picture of your head and both ears. I went through the whole process.
There are a lot of options in the app, and the layout is OK. It can be a bit confusing.
The app does provide a lot of control and information. It shows battery level, and the current codec in use. This last part I really like, Apple typically doesn’t show these details. Many options can beyond simply being enabled or disabled from the app can also be further controlled.
Case, accessories
A nice rigid fabric coated and lined travel case is provided. It is similar in size to the Bose QC35. It appears that it would protect the headphones and hold up well with travel.
A 3.5mm to 3.5mm cable is included. This allows using the headphones with a wired source, such as an airplane entertainment system. The cable does not have a microphone or controls and will not control and iPhone, iPad, or Mac or support calling. It is only a 3-conductor plug for stereo listening.
While the Bose QC35 headphones come with an equivalent cable, the Bose QC25 cable, or the Amazon Basics alternative cable can be purchased that does allow using the QC35 for phone calls, and wired remote.
Also included is a short USB-A to USB-C charge cable, no charger, and the old 2-pin airplane adapter.
My only concern are all the articulating hinges as far as reliability. They appear OK, but I wouldn't abuse these headsets as they may let you down... Not sure. I take care of my stuff.
The comfort is outstanding. The frequency response and resulting sound is very good. I'm an old school eclectic Cerwin Vega real wood frame heavy ass 4 way floor speaker guy. Nowadays, considering what I have been trying to use for private listening, these rock. My Samsung buds2 Pro sound good, but I'm tired of frequently resetting ear buds in my ear for fitment!
One more thing, I plan on a commercial flight of 3+ hours in a couple of weeks and then I'll be able to rate airplane noise, however, in a home or public space, these headphones have spooky good noise canceling. Only complaint is the app default is full noise canceling and I find myself having to reset that to my liking every so often.
Capacitance touch/gesture motions are something that I'm getting used to.
NOW THE COMPLAINT ... I easily paired these XM4's with my Dell XPS 17 9710 Windows laptop. However, there appears to be no Windows app or way to adjust anything other than volume... Isn't this 2022?...HHMMMM...unfortunate
Overall, enjoying my Sony WH-1000XM4 Headphones!

Older review
This is my first Bluetooth headphone, never been fan of Bluetooth because of poor audio quality. When Sony released ldac codec i was really happy and was waiting for xperia but they decided to close their mobile division. After that was waiting for pixel 4 but google’s mobile division has bunch of idiots.
Finally bought iPhone which has crappy audio quality but I suggested one of my senior xm3s and to my surprise they sounded really well on iPhone too. After lockdown i was really frustrated with the news channel that my parents watches. Waiting for xm4 can’t be more painful.
Now coming to review
ANC: i felt no difference compared to xm3, they block the rumble of fans, coolers and pump set but are unable to block the voice of people talking(irritating voice of arnab goswami). They didn’t even changed xm4’s pressure inside the cans after anc is enabled. I still get the same headaches.
Audio quality: not going to write like pretentious audiophile. These headphone are quite versatile if you are bass head then sony has it covered for you (which most of the people like here), bass was way overpowering for me on full setting but i don’t like bass at all. I mostly listen to linkin park, so i set base level at -4 and equaliser on bright preset. This is by far the best audio product i have ever used.
Audio quality wise here is my ranking.
SM es 18<Creative ep830<SM e10s<Fiio f9 pro<one more triple driver<xm3<xm4.
Battery life: I was doing burn in procedure of these headphones, so i kept headphones at max possible volume, so you may get better battery life. I got 18 hr of battery life with anc on. After unboxing battery went down from 100 to 60 in a 10 min and i was afraid that i got faulty unit but thank god a full charge fixed it.
Comfort:Ear cups are bigger than xm3s and hence more comfortable too. After walking with them for half an hour on roof my ear got all sweaty.
Multipoint connection: Works flawlessly, although switching music from one device to another is bit erratic.
Audio lag: I also connected it to airtel xtream box and watched a complete episode of boys with no lag at all.
Speak to talk: still prefer the old put you hand on right ear cup.
Pause when headphone taken off: work 8 out of 10 times.
360 deg reality audio: sony has give 3 months of free subscription of nugs.net but difference was not deal breaker.
Accessories: you get 3.5 mm male cable from both sides, thank you sony for that. Charging cable is really short i mean really. You can use the provide cable just with power bank or laptop. You also get airplane adapter and carry bag too.
Sorry forgot about mic
Mic: It is better than my iPhone 11 pro, my friend used to complain a lot about low volume from my side but with xm4 they had no problem talking to me.

É de plástico duro de muita qualidade, tem um toque meio aveludado, o preto é fosco e passa bastante robustez.
CONFORTO 8.5/10
É acolchoado na parte superior que encosta na cabeça e isso é muito agradável. As almofadas da orelha são muito macias e de couro sintético, mas gostaria que fossem mais preenchidas, parecem meio finas. Minhas orelhas não encostam na almofada e se encaixam totalmente dentro delas, o que é ótimo. Se uso mais de 50 min elas esquentam e, as vezes, ficam um pouco doloridas, mas se tirar 5 minutos já passa e voltam ao normal.
SOM 9/10
É de muita qualidade, a nitidez e a capacidade de atingir graves e agudos é excelente. Contudo, não gostei da calibragem de som original do fone e isso me frustou bastante no início. Minha felicidade foi descobrir que o fone se adapta MUITO bem à equalização. Sempre usei o equalizador no Spotify porque tenho um gosto muito específico de som e, mesclando ele junto com o equalizador do aplicativo do fone, cheguei a um som que me agrada bastante. E foi de quebra bem legal ver que, se eu quiser, posso focar diferentes tipos de som (graves, agudos, médios, vozes…) que ressaltam diferentes partes das músicas apenas com a calibragem do equalizador.
VOLUME 8/10
Confesso que eu esperava que o fone fosse capaz de atingir volumes mais altos. É bom, e o isolamento de ruído permite maior qualidade e imersão em volumes mais baixos. Mas teve momentos em que gostaria que ele fosse capaz de subir só mais uns 15% no volume. Desde o volume zero ao cem confesso que fiquei impressionado porque não percebi nenhuma perda de qualidade ou nitidez no som.
BATERIA 7/10
Só dei 7 porque foi anunciado 30 h e consegui zera-la em 15. Particularmente eu acho 15 horas uma autonomia bem respeitável, só é beeeem diferente do anunciado… Dentre os diferentes usos que já fiz eu consegui entre 15 e 27 horas de autonomia, ficando numa média de 20/22 h de autonomia por recarga (que faço de uma a duas vezes na semana durante a noite).
CANCELAMENTO DE RUÍDO 7.5/10
Polêmica. Eu nunca tinha usado um fone com cancelamento de ruído antes e além do receio de não ser bom eu não tinha ideia do que esperar já que não tinha nenhuma experiência prévia pra comparar. Achei interessante, mas nada de extraordinário. Ajuda BASTANTE no conforto acústico mas deixar passar barulhos externos sim. Tem um pessoal muito pessimista e outros muito otimistas fazendo avaliações, ou ama o fone ou odeia, e eu, particularmente, prefiro os realistas. Olha, pra ruídos baixos e repetitivos como ar condicionado, ventilador, metrô, avião (etc) é simplesmente sinistro como o fone é capaz de tirar praticamente 90% (de vez em quando 100%) do barulho, é como entrar numa realidade paralela. Eu uso pra estudar, sem música e só com o cancelamento de ruído ligado e escuto o meus colegas virando a folha do caderno, batendo o lápis, cochichando, mas isso é ruído de fundo, como se esses barulhos perdessem de 60% a 80% do volume e, dependendo da minha concentração, é como se nem estivessem lá. De vez em quando rola uma pressão no ouvido assim que ligo o fone, mas rapidinho eu acostumo e não me incomoda. A redução de barulhos ajuda MUITO na qualidade e clareza do som quando você tá ouvindo música. No app tem como otimizar o cancelamento fazendo uma análise do ambiente e da pressão atmosférica de onde você tá e é impressionante como isso ajuda na qualidade do isolamento em diferentes situações. Minha conclusão é que ajuda muito, de fato tira muitos barulhos do ambiente e reduzem muito o volume de outros, mas não é 100% não.
ENTREGA 10/10
Comprei numa quarta feira e chegou, literalmente, na quarta-feira seguinte. Fiquei impressionado com a rapidez de importação e da clareza com o transporte pela empresa que enviou. Moro numa capital e isso deve ter colaborado pra ter chegado rápido, mas mesmo assim, atravessou meio mundo em uma semana kkkk
CONTROLES e TECNOLOGIA 7/10
É tudo touch, volume, pausar, pular ou voltar uma música. Não achei particularmente intuitivo e muitas vezes vou fazer um comando e acontece outro. Preferiria muito mais se esses controles fossem em um botão físico como no Bose. Algumas funcionalidades não precisam de “atualização”, um botão físico seria bem mais prático que ficar esfregando o dedo na concha e tentar acertar o gesto… O modo transparência é interessante, mas não uso porque acho muito mais prático e eficiente (e menos rude) tirar o fone pra prestar atenção em algo. Tem uma função que, ao tirar o fone, ele automaticamente pausa a música e, ao recolocar na cabeça, ele automaticamente reinicia a música, é uma funcionalidade incrível e eu adorei como ela funciona bem. Além do mais, se você deixar o fone fora da cabeça por alguns minutos ele logo desliga, automaticamente, e não gasta bateria atoa, o que é ótimo!
CUSTO BENEFÍCIO 6/10
Vale o preço original? Não. Eu comprei numa promoção de 25% o que, ainda assim, acho que estava mais caro pro que esse tanto de tecnologia de facto vale. Acho que é um fone que valeria pagar no máximo 1.500 reais mas, nessa faixa de preço, NÃO existe no mercado qualidade de som, bateria, e cancelamento de ruído à altura desse. Estamos refém desse fone porque, para o tanto de tecnologia que ele oferece, ele é, dentre os outros, o mais barato (se é que se pode chamar isso de barato…). Se for pra comprar, tente esperar uma promoção. Quem rala igual ao brasileiro não merece pagar mais de 2.000 reais nesse fone não, dê valor ao seu dinheiro!
CONCLUSÃO 8/10
Espero ter ajudado alguém, quando fui comprar tinham avaliações muito genéricas ou cheias de opiniões ao invés de argumentos concretos sobre o produto. Quando o investimento é grande assim, quanto mais informação conseguir antes de comprar melhor. Particularmente gostei de comprar e não me arrependo, ter essa tecnologia toda um um fone é bem legal, MAS não acho que compraria de novo nessa faixa de preço não. Espero que façam uma boa decisão!

When I received it, I was amazed how good everything sounded through them, and how well the noise cancelling worked. And they were comfortable to boot!
However, the next day I did my first Zoom call, and a colleague told me that I sounded like I was in a tunnel, and that he couldn't make out what I was saying. I switched to my old Bose set, and everything was fine.
That evening, i called Sony support. I spent about 30 minutes on the phone with the very nice support person, including making calls from my phone vs my computer, resetting the headphones, etc, etc. It didn't help. He denied that he had heard of microphone problems before. He asked that I send the headphones to Sony for a replacement, thinking that they were a lemon, but I told him I'd rather just return them to Amazon. Which I did. requesting an identical replacement.
A day later I had the new ones. And there was the same problem of poor mic quality, with weird static-like sounds and muffling. At this point, I decided to solve the problem. I tried the following, using recordings of Zoom calls to monitor the quality:
1) Single vs dual bluetooth connectivity.
2) Different microphone volume settings.
3) Different degrees of noise cancellation (including none at all).
And probably a couple that I am forgetting.
Nothing helped the poor mic quality. I then really searched the web, and found out that although there are plenty of wonderful reviews, hidden in the reviews where the mic is used are clear examples of problems with the microphone.
I then called Amazon to request another return, but used the microphone from the headphones, and then switched to my phone. The representative could hear the difference easily, and said she had trouble understanding me when I used the headphones.
So I am giving up, and will buy a different brand. I am writing this long review to spare my fellow Amazonites who need to use a microphone the pain of having to return items.
Of all the comments that have been said about being not enough this, not able to do that, I think they are all untrue or either an unlucky manufacturing defect. Launch products are not perfect from the start, it's bound to happen. The only thing I do not use are the microphones for making calls, so you can check online and see for yourself about that aspect.
Let's break this down in points. (TLDR at the bottom)
Comfort/Ergonomics:
Without a doubt the most comfortable headphones I ever wore. People seem to complain that it's not as comfortable as the XM3s, I say it's pretty dang comfortable considering that I wore this thing for more than 5 hours straight and had no neck pain or itching whatsoever.
The weight of these headphones is so light that when the box came in, I thought I had been scammed and the headphones weren't in the box. 250 ish grams is really light (0.55 pounds) for headphones.
The ears are big enough, the line of the muffs doesn't overlap too much towards the neck and the cushion material adapts really well to your head, both on the top of the frame and on the ear muffs.
Sound/frequency response:
I have been mixing/mastering for multiple years on flat studio monitors. Out of all the headphones that I have or I have tried, these are the closest of being pretty much flat, once you cut 3-4 dB from the 400 Hz fader (pretty sure it's an octave bandwidth, or a little more, so it covers at least from 282 Hz to 566 Hz when you adjust it) on the equalizer in Sony's Headphones app.
I have attached the frequency response curve as an image in this review.
The bass is not overwhelming, (although if it's your style, it delivers with the clear bass knob, which probably covers 250 Hz and below), the highs are not too sharp and there's no spike in the high mids (2500-5000 Hz) or in the high end (above 5000 Hz).
The only problem is the low mids at around 400 Hz, which thank god they have a fader for that frequency. No matter what brand you choose, low mids are ALWAYS a problem in headphones. By the way, sound separation is excellent once I made that adjustment. Thank Sony for giving you the option!
The frequency response when using Bluetooth is between 15 Hz to 17 040 Hz. Beyond that, it starts to wane off. I have up to 19.1 kHz in my right ear and 18.3-18.4 kHz in my left ear, so it's not on my side. Considering that my phone has a terrible audio output (it cuts at 15 kHz), it's an upgrade for me.
Also, considering on how many people listen to their music too loud for the last 25 years, I would be highly surprised that people that claim the high end isn't well defined actually know what they are talking about, and most probably don't notice the difference. Same thing with audio CODECS disappearing from the XM3 (the XM4 has 3 and the XM3 had 5), above 256 kbps at variable rate and 320 kbps at constant bit rate, you don't notice anything if the conversion was done right. Above those values, me and my friend call this "Placebo Quality". Compression and brickwalled mixes affect the quality perception GREATLY.
Search NPR sound quality test online. It proves my point.
So in conclusion, if the song you are listening sounds like garbage, it's because it was mixed/mastered like garbage (probably mixed nowadays because they brickwall often at this stage). These are hands down the best headphones I ever tried. Period. Including my Sennheisers that I used for multiple years.
Noise cancelation:
I was highly surprised at not only the sensation on your eardrum being pushed in not being super apparent compared to other models, which are quite frankly unbearable in the long run, but also the capabilities of phase canceling of these headphones (the actual term of canceling out waveforms is called phase canceling, noise canceling is a marketing term for people not familiar with audio, since the majority of people don't know what is phase).
Transients (such as impacts) are impossible to isolate because they are too fast to sample and to invert the phase to create cancelation. Steady noises are the only ones that allow the headphones to sample them and invert them, because there's a processing delay. Stop hitting a table like someone I know was doing to test headphones, it's worthless.
The amount that is being canceled out is out of this world compared to previous generations that I have tried. I can't wait to try them on a plane. High end will remain because it's the most difficult part of the waveform to cancel, since it's the most precise and the one that takes up the most information in a signal. I was standing next to a washing machine during its max spin cycle, could barely hear it with audio of people talking in my headphones. Without playback, you hear the high end when you're right in front of it. As soon as you close the door, it pretty much vanishes.
If you have noisy neighbors or live in an apartment, buy this thing! You won't regret it.
Battery life: Outlasts my cell phone by a hundred years. In 2 hours of use, not even 10% used. Specs are believable.
In conclusion, buy this thing if you are looking for noise canceling!
TLDR:
-Super comfortable
-Amazing in sound
-Amazing in noise canceling and battery life matching specs

Got the replacement set and they sound do much better than the first ones I recieved. This kind of issues is unheard of from a product that costs 30k not gonna lie. Seriosuly? A defective pair of headphones ? Unexpected sony !
Update- sept-25
So I was using these like.usual when I started hearing a shrill noise from the right side earcup! Tried it with multiple devices , persistsnt shrill noise with noise cancelion and no music( my room's fan was off ) . Replacing for a new pair . Will update
I'm not a "audiophile" but I've tested and heard many headphones/earphones in search of the "perfect" pair of cans for me. Perfect is a subjective term and will vary from person to person.
I bought these becasue of all the hype with the xm3's and as a customer the "next" version would obviously be better right ?
So, come delivery day. I ooened these, set them up, updated the firmware and started listening . These sound , ok. For something that costs 30k, these sound average at best. The noice cancelling is good but I need to test it more , possibly on an airplane ( whenever that happens )
When something is this expensive you automatically have some expectations from it right ? It has to perform at the 30k level ( I hope the reader is getting what I'm trying to say) .
The software features are great , the build feels premium, the connection is strong.
P.S if you intend to use the multipoint function you will loose audio quality . LDAC uses two lanes ( max for bluetooth 5.0) and when you use multipoint it switches to SBC ( 1 lane ) so expect quality loss. Windows doesn't support LDAC so you will loose significant quality when connected to a pc.
I'll update the review after the burn in period . I won't be returning these since these are just too damn comfortable but doesn't justify the 30k price tag it demands for the sound quality I'm getting as of 20 sept.
