Sony WH-1000XM4 initial review: Has the best got even better?

Quick verdict

Sony has year-on-year set up itself at the head of the remote headphones game and the WH-1000XM4 shows that pattern proceeding. Our underlying considerations are that the improved solace and changes in sound tech put them among the top ANC over-ears out there, if not at the exceptionally top.


  • Even more comfortable
  • Improved noise cancellation algorithms
  • Superb music playback for high-res and compressed tracks


  • Maybe not enough of a generation leap to upgrade to


Since Sony entered the clamor dropping earphone field, with the MDR-1000X in 2016, many have strived to keep up. There are a bunch of brands that contend in a comparable value class, with some phenomenal options out there, however despite the fact that we’ve just had two or three days with the WH-1000XM4 up until now, it appears that the firm has increased current standards again.

We will place them through a more exhaustive test in the coming days, however here are our underlying musings on Sony’s most recent remote commotion dropping over-ears.


  • Fine-tuned headband curve
  • 10 per cent larger earpads

The Sony WH-1000XM4 headphones seem to be like their latest ancestor, yet a couple of minor changes make for a more agreeable wear for longer periods.

They are a smidgen lighter, first off, with a rebuilt headband and slimmer head pad. The earpads are bigger and milder, while the earcup itself is marginally more slender.

The final product apparently after short eruptions of testing – is that they feel cozy yet without the snugness or heave of certain opponents, which make those specific models precarious to wear on a long stretch flight, say.

Frankly, we’ve generally been intrigued with the Sony’s for comfort, having utilized the first 1000X and 1000XM3s on trips before. Normally, it’s precarious to do likewise with these during the pandemic, however we can’t perceive any reason why they would be any extraordinary, if not far and away superior.

Tech and features

  • Adaptive sound control
  • Bluetooth
  • NFC
  • Google Assistant / Alexa support

There is a lot of new tech both in and outside of the headphones, with improved clamor wiping out, new advanced sound upscaling abilities and general use upgrades.


Another proximaty sensor inside the left cup recognizes when the 1000XM4s are evacuated, delaying playback and in any event, turning them off altogether (following 15 minutes) in the event that they are left torpid.

Contact sensors on the external right cup return, empowering track skipping, volume controls and play/delay, while another element permits you to hold your hand over the cup to incidentally bring down the volume and turn on encompassing sound so you can hear what’s happening in your environmental factors.

Significantly more amazing is the capacity to naturally delay sound playback and turn out surrounding sound by basically. Simply begin to talk and the headphones will switch into “address visit” mode, so you can have a discussion without expelling the headphones. At that point, when completed, the music fires up once more.

We haven’t got an opportunity to test this appropriately yet, considering the current lockdown measures in the UK, however can unquestionably observe the potential. Having the option to converse with a flight attendent without halting what we’re tuning in to first, for instance, will be extremely convenient.

Versatile sound control has been included this time around. Interface the headphones to your iOS or Android gadget through the devoted Sony application and you can set them to naturally change the commotion dropping properties relying upon your condition. This is something we used to extraordinary impact with the Sony WF-1000XM3 genuine remote earbuds.

This time, nonetheless, the ‘telephones will likewise modify the ANC signature relying upon most loved areas. Utilizing your telephone’s GPS, it can store extraordinary, much of the time utilized spots to in a flash change to the sound mode most appropriate. Once more, we haven’t had the option to test this completely because of an absence of movement, yet it positively sounds flawless, and every one of the encompassing sound modes work incredible from our underlying testing.

Regarding different advances, the 1000XM4s are perfect with Alexa, Google Assistant and Siri, while upgraded Bluetooth availability currently permits you to interface with two gadgets at the same time. You can switch between them basically and the ‘telephones will organize approaches one gadget as you tune in on another.

Audio Performance

  • High-Res Audio
  • 360 Reality Audio
  • QN1 NC processing, Bluetooth Audio SoC
  • DSEE Extreme upscaling

Taking into account how extraordinary the 2018 XM3 model sounds, this was the region that required minimal measure of progress. In any case, work has been done to guarantee only that.

A similar commotion dropping chip is utilized – Sony’s own QN1 – however it has now been combined with another Bluetooth Audio SoC (framework on-chip). These consolidated improve the ANC calculation.

Fundamentally, while you may never genuinely see the distinctions, more surrounding commotion can be separated than previously, without influencing the listening experience.

Furthermore, the headphones currently accompany DSEE Extreme innovation, a generational jump over the framework utilized in the previous gadget. It utilizes new Edge AI smarts to encourage upscale compacted sound records to sound practically lossless. In fact, our test tracks we’re principally standard 192kHz MP3s and in this way required the work to get them to sparkle.

The 1000XM4s are additionally guaranteed for 360 Reality Audio – Sony’s own virtual encompass sound document type.

While you don’t explicitly require a committed pair of headphones to appreciate the tech – it’ll chip away at any – we especially delighted in tuning in to Liam Gallagher’s Unplugged gig accessible in 360 on Tidal. A spot of Elvis went down a treat as well.

Unusually, the Sony Headphones Connect application takes photographs of your ears to modify the 360 experience particularly for you, and in spite of the fact that we’re not actually sure what slyness is being utilized, it absolutely works.

These are remarkably acceptable headphones for sound quality – with ANC both on and off.

Battery and Charging

  • 30 hours battery life (claimed)
  • Fast charge – 10 minutes for five hours playback

We didn’t generally have the opportunity to test the battery life of the Sony’s ourselves. In any case, an asserted 30 hours will be exceptionally great on the off chance that it gets close to that.

We checked the charging claims however, and need to state that the 10 minutes of charging for five hours of playback is profoundly welcome.

In actuality, as the wearing identification kills the headphones altogether following 15 minutes of reserve, we question you’ll charge them that regularly. At the point when we test more, we’ll be intrigued to perceive how long we can leave them torpid and afterward get them once more.

Remote headphones have gone ahead a far cry as far as battery life span as of late, that is without a doubt.


First Impressions

Normally, two days of play isn’t generally enough to concoct a complete sentiment, yet as of now the Sony WH-1000XM4 headphones are intriguing.

The sound quality is magnificent – as we’d anticipate from the genealogy – and they sport the’s brand name comfort levels.

Immense steps have plainly been made with the commotion crossing out tech, while different changes make for a possibly class-driving item.

Unfortunately, we’re probably not going to travel significant distances at any point in the near future, so it’ll be difficult to test them at their best.

Be that as it may, considering most of every one of us have children thumping around the house at the moment, having the option to escape in our preferred melodic or film interruptions without the outside discord put these high on the plan in any case.

Accessible in dark (as tried) or silver, the Sony WH-1000XM4 remote commotion dropping heaphones will be accessible later this late spring, valued around £350/€380.
