I bought these headphones a month ago and I have thoroughly impressed with the quality of the sound and the noise cancelling feature. It does take some time to get used to the app and all of its qualities but after a week or so I was able to use the adaptive sound control to recognize my most frequently visited locations and already have the settings I want for that place ready to go. The multi-device feature works pretty well, sometimes there is a hitch in switching from my laptop to my phone or vice versa with certain apps, but for most uses it works seamlessly. They are really comfortable and I wear them for hours at a time with no issue. Highly recommend these!

[This review was collected as part of a promotion.] I absolutely LOVE this Sony wireless headphone. The WH-10000xM4 is one of the best headphones I have ever had. The sound has a remarkable crisp sound compared to anything on the wireless market. Along with the sound, the sound control and noise control, this make these headphones groundbreaking. The noise-canceling works phenomenally as vacuuming and other background noises can not be heard at all. This changes the market for noise-canceling headphones. They are easily adjustable making them fit great comfortably. Paired with the easy action of raising the volume and switching songs, the headphones make them easily accessible. The combination of sound, fast charging, accessibility, and performance makes the WH-10000xM4 one of the best noise-canceling headphones today. Overall, this is excellent headphone on the market.

I bought it a month ago and while my experience with them is good - all of the features are there, but the implementation of a lot of basic functions is pretty bad. Tap controls are often registered after third or fourth try and after headphones register it, the controls work just fine. This is definitely a bad optimization for battery saving. Chose one - physical buttons and battery optimization or touch controls and no battery optimization. You can't have both. "Pause when taken off" function isn't great either - it often starts playing when my headphones are around my neck. Turn on/off with button hold is a bad implementation (even if you must use the hold button, why is it so long? It's long enough so that it feels cumbersome and instead of instant turn on/off, it's an operation onto itself). Also, there is no way of seeing battery level while the headphones are charging which is laughable.

[This review was collected as part of a promotion.] I got these to experience everything good I've heard about these noise cancelling headphones and they live up to what I've been hearing! There wonderful! They really do block out the background noise and I'm having a great time with these! I've told ally gilt and friends. Never know.

[This review was collected as part of a promotion.] This is my first set of noise cancelling headphones. They appear well-made and have impressive features, which include bluetooth, touch sensors, voice-command functionality, and excellent audio. They even come with a nice-looking storage case. If you know that you enjoy wearing noise-canceling headphones, I'd recommend these for you. However, I do not enjoy the suction-cup feeling on my ears when wearing these, and they make my ears feel hot and sweaty. Also, there is a low hum sound that is unpleasant to my highly-sensitive hearing. I cannot see myself wearing these for more than an hour at a time.

I had been waiting for these headphones for a long time to upgrade my Bose QC25s and purchased them on the day they became available. I'll break my review up into sections: Fit/Comfort: The first thing I noticed when I tried these on was my ears touched the fabric that covers the audio driver. This never happened with my Bose, but I figured maybe I could get used to it (although I've had these for 3 weeks and this still bothers me). Ideally I think the foam should be thicker to prevent this. I also noticed these headphones didn't seem very comfortable after about 30-45 minutes, which isn't very long for me. Maybe I have an odd-shaped head based on other reviews I read, but I was disappointed by this especially considering I never had this problem with my Bose headphones. The headphones also get very warm, which can probably be attributed to the seal around my ears for noise cancelling. I can't really fault the headphones here as noise cancelling is a priority, but this is just an observation. Sound: The sound is really good. I still don't think it competes to headphones that don't have ANC but I don't really think that's possible. Overall I was happy with the sound. The noise cancelling is phenomenal, and these headphones do a great job of cancelling even mid-frequency rather than just low frequencies. Features: I'm not really sure if something is wrong with my pair, but the switching between bluetooth devices is very buggy. I still have to manually disconnect and connect my devices fairly often which is disappointing as that's probably the biggest feature of these headphones versus the X3. I've also had devices that are connected and playing but no audio comes through these headphones (and I have confirmed only 1 connected device was playing audio at a time). The touch controls are pretty nice, I do wish the custom button could be used for the conversation mode but that's a minor gripe. The swiping controls work great and I love the feature of putting my hand on my ear cup to hear my surroundings. Overall: I really can't justify the price of these headphones for the poor fit (which may just be a personal problem) and the buggy tech such as the multi-device bluetooth support (which is the biggest upgrade from the X3 in my opinion). At this price I would expect a nearly flawless device. I really wanted to love these, but unfortunately I think I'll be returning them and trying out some other pairs. I really hope I got a bad pair which I think is a possibility based on other reviews I've read, and I think these headphones are definitely worth a try from a store that allows returns.

[This review was collected as part of a promotion.] These headphones are Fantastic! They definitely are noise canceling. They are extremely comfortable to wear and the ear pieces don't hurt. Soft to the touch. Had them on for a couple hours forgot I was wearing them. The sound was also amazing. No glitches or murmers in the speakers.

This is my third Sony high res headset I own. I bought last week mainly because of 2 new features I didn't have on WH-1000XM3. I really lowed WH-1000XM3s because excellent sound quality. On XM3 NC worked fine in the office, but sometimes had issues outside withe repeated sounds, let's see how XM4s will perform.. I use the headphones in the office and support for 2 devices is finally supported, but NOTE there is something specs and advertisements don't say. If you enable this feature the LDAC is gone and it will switch headphones to AAC 44khz/16bit only. So my question to Sony is if it would be possible to keep for example LDAC (2 channels) on phone and AAC for laptop with some future firmware update? I'm switching between modes often to enjoy TIDAL music in better quality, but another issue is that headphones don't reconnect to second device automatically. So you need to enable second device support in the menu and go to different menu to reactivate second device. Another idea to Sony: Make this as an option to button and reconnect to second last used device automatically. Second new feature I really like is new sensor which will stop music when you take headphones off. I experienced some small issue today. Not sure if it was the trigger, but I walked with phones off my ears and heard email notification coming to headphones an then music started playing. I just moved them a bit and music stopped again. I was hopping for redesigned touch control which is quite a pain. Maybe next time? I have a feeling that NC is better even passive when headset is off. Comfortable to wear even outside on the street. Didn't experience any troubles like on previous model, but maybe I didn't met similar conditions yet. With XM3 the issue was for example in train when window was open and columns along the trail were creating specific noise. The headphones generated even louder noise and the only solution was turn this feature off. There are new mics inside which might hopefully prevent this situation. So some improvements are still needed, but overall the sound quality is still outstanding and I'm still ranking 5 stars.

[This review was collected as part of a promotion.] I normally use earbuds because most of the headsets I have tried don't fit on my larger head. This headset not only fits great the sound quality is amazing with the noise canceling feature i couldn't hear any surrounding noise.

[This review was collected as part of a promotion.] The quality of the Sony WH-1000xM4 headphones is 8/10. I like the noise cancelling feature. The sensory touch is also cool to use. I do however do not feel too much of a difference when it is optimized. The quality of the box it comes in isn't as great though.
