Ease of use and sound quality

These are comfortable headphones. This was the first thing I noticed when I put them on. The sound is crisp, although a little bit tinny. This could be something that could be fixed by adjusting the settings in either my phone's audio player (Audiolet) or with the Sony headphone app. Battery life is good, however. BTW I got them in the grey colour which is a cool alternative to everyone else who gets them in black.

Ive been using noise cancelling headphones for a few years (Plantronics Backbeat Pro), and upgraded to these ones. The jump in active noise cancelling performance between these is absolutely stunning. Peoples voices turn into a quiet barely audible tinny sound (far, far superior to the BB's), and background hum is utterly gone. The first words out of my mouth when hearing the noise cancelling performance while people were speaking…well, they cannot be repeated here. Lets just say, im very impressed. Music performance is good, not too bass heavy. The reviews are right, these are the best out there.

Read the reviews before buying and they were right. These are amazing with outstanding sound quality.

After finding that many Bluetooth headphones had functions or features that proved to be complicated, these headphones are straightforward to use from the start, with built-in features you can manage via an app rather than on the headphones themselves. Would definitely recommend for anyone looking for a straight-forward pair of Bluetooth headphones with great sound quality.

These are Sony's premium ‘flagship’ headphones for 2020 and the quality is outstanding! The price is up there, but these headphones out perform anything currently on the market from others (Bose, Sennheiser, Beats, JBL, etc.) The only tip I can offer is be very careful if you buy the silver colour, marks, bumps and scratches stand out compared to the black ones so that's something to consider. Again these are THE BEST audio & noise cancelling headphones you can buy (so far) hands down.

It lives up to it's name, the noise cancellation is great! Been a month since purchase and is still good!

These noise-canceling headphones silence the world better than most, and the mics are now actually usable on phone calls.

Top-tier noise-canceling. Fantastic audio processing and digital upscaling. 30 hours of battery life. Light and comfortable. Intuitive app-based controls. Connect two devices at once.

Somewhat drab design.

The Sony WH-1000XM4 ups the ante in every way to challenge the Bose 700 for the title of best noise-cancelling headphones. Delivering small but significant enhancements in a familiar package, the Sony WH-1000XM4 is a strong contender for the best noise-cancelling headphones you can buy.

Excellent audio quality, Remarkable noise cancellation, Smart controls, Strong battery life, Lots of useful features

Call quality still needs work

Finally someone has beaten Sony in the noise cancelling headphones department. And it's Sony! The WH-1000XM4 is the new leader.

The world's best noise cancelling has gotten even better. The audio quality is also better than the predecessor, and important functions have been included.

Still somewhat lacking in the resolution and airiness department. There are other ANC headphones with better music audio quality. Slight latency with games (aptX support has been removed).
