To say I’m familiar with Sony’s 1000X line of headphones would be an understatement. I’ve tested every pair thus far, except the OG: the MDR-1000X. With each successive model, the company managed to add new features, develop better technology and expand the sonic capabilities of its flagship headphones. And with each new release, Sony kept its spot atop our best wireless headphones list.
This time around, Sony made us wait longer than usual. The first three sets of 1000X headphones each arrived a year apart. Then it was two years between the WH-1000XM3 and WH-1000XM4, perhaps delayed in part by the COVID pandemic, and then nearly two more before the redesigned WH-1000XM5 debuted. We’re three years out from that last model and today Sony is finally revealing the follow-up: the WH-1000XM6 ($450).
The extended interval is understandable once you consider the number of updates Sony has included to overhaul its pride and joy. There’s a new processor, more microphones, improved active noise cancellation (ANC), refined design and a retuned sound platform. Those changes join the long list of features Sony has amassed on the 1000X line over the years, a number of which automatically adapt when enabled, and many that provide great convenience in daily use. Other companies may have surpassed Sony in audio quality (at least until now), but none of the competition offers a collection of tools that even comes close to the WH-1000XM6.
Design updates
At first glance, the WH-1000XM6 might not look much different from the M5, but there are some notable tweaks that improve comfort and storage. First, there’s a wider, asymmetrical headband that makes these headphones even easier to wear for long periods of time. The previous model was already lightweight, and that continues here. Together with the new headband, it provides a comfy fit that beats every other wireless headphone.
Next, Sony returned to its folding design that older 1000X models used to have. With recent models, the company opted to just let the ear cups rotate before the headphones went in the case. They still do that, but they also fold in for easier storage. Due to this change, the company designed a smaller case, and instead of a zipper, Sony chose a magnetic closure.
One complaint I have about the design is how the ear cups rotate. When you take the WH-1000XM6 off, the cups rotate inside up to lay flat. To me, it should be the opposite, with the ear pads flipping down, because that’s how you’re going to put them in the case. This is a change from the M5, where the ear cups turn in what I’d consider the correct way, which makes this switch an even more confounding choice for this new model.
Sony mostly kept the controls on the WH-1000XM6 the same, save for a couple of small revisions. First, the company still uses a mix of physical buttons and touch panels on the outside of each ear cup. With the former, the only two options there are power (which doubles as Bluetooth pairing) and the noise control button that cycles through ANC, ambient sound and off.
That power button was redesigned so it’s now larger, round and concave. This makes it easier to find by touch and differentiates it from the noise control button. What’s more, Sony has added the ability for users to mute/unmute the microphones on the M6 during calls by double pressing the noise control button. This is handy when you don’t want to reach for your phone or keyboard during a voice or video chat.
Improved sound quality
The 1000X line has never been a slouch when it comes to sound quality, and Sony has made strides to continually improve audio performance over the years. With the WH-1000XM6, the company made changes in three areas to further boost the sound profile. First, Sony developed new drivers for the M6, which it says deliver “richer details and clearer vocals.” That’s due to what the company describes as smoother, extended high frequency reproduction created by perforations in the driver’s voice coil. And there’s better overall balance in the sound too, thanks to a more rigid dome for these components.
The company also enlisted mastering engineers from three recording studios to help tune the sound profile of the 1000XM6. They all contributed various quotes praising the audio quality of these headphones, but the general goal here was to deliver results that were closer to the artist’s intention. That includes more immersive sound and finer details. To further aid this, Sony also added 360 Spatial Sound upmixing for stereo content on the M6. Essentially, this feature can turn regular content into spatial audio. It’s something similar to what Bose does on its QuietComfort Ultra headphones, and it’s separate from both 360 Reality Audio support and DSEE Extreme compression upscaling.
On Sleep Token’s Even In Arcadia, the WH-1000XM6 provides boomy bass when tracks call for it, like the loud, crunchy guitars and thundering drums in “Look To Windward.” Throughout the album, treble and mid-range cut through cleanly, providing ample separation so you can hear all of the elements clearly. And that’s no easy feat, given the genre-bending production the band employs. Plus, the big, soaring, loud parts of these songs seem to completely surround you with sound.
The recently remastered The Musings of Miles by Miles Davis exhibits a different side of the M6. Here, the textures of the instruments are what stand out, where you can hear the subtle nuances of the trumpet, piano, bass and drums. I’m not sure there would be much more clarity if you time-traveled back to Rudy Van Gelder’s home studio in 1955. The audio is pristine here. There’s a similar vibe given to Billy Strings & Bryan Sutton’s Live At The Legion, where the two bluegrass virtuosos lend only two acoustic guitars and their voices to the show. Listening to this album with the M6, I might as well be sitting between them.
New chip, more mics and a dash of AI
Inside the WH-1000XM6, the star of the show is the new QN3 processor. Sony says it’s seven times faster than the QN1 used in the M5, a chip that first debuted on the WH-1000XM3 in 2018. Given that’s the main power behind noise cancellation, it was definitely time for an update.
With the QN3, Sony was able to add four additional microphones for its ANC setup, bringing the total on the 1000XM6 to 12. More mics means the company can more effectively detect and block noise. Alongside the new hardware,, Sony upgraded the Auto NC Optimizer on the M5 to what it now calls the Adaptive NC Optimizer on the M6. This technology accounts for changes in fit and air pressure, automatically adapting the ANC coverage as needed. What’s more, the company says the M6 can block more mid-to-high-range frequencies than the M5, putting all of that power to good use.
There’s a noticeable improvement in ANC performance on the M6 — it’s not just marketing hype. I can easily tell the headphones are blocking more background noise than their predecessor, which isn’t always the case across 1000X generations. Particularly with human voices, this model does a better job of reducing the sound of chatty neighbors in the office than much of the competition. Even though it doesn’t entirely silence them, this still constitutes an upgrade in performance. The company has been giving Bose a run for its money for a while now, and the M6 further cements the fact the noise-cancelling arms race is closer than ever.
Like it did on the M5, Sony employs AI-based noise reduction on the M6 to reduce background noise during calls. The company says it trained its model on 500 million voice samples so the system can properly extract the user’s voice. What’s more, Sony now utilizes two additional microphones for voice performance (with a smidge more AI on them) that are better positioned for speech pickup.
In practice, call performance is a mixed bag. First, the M6 does an excellent job of blocking background noise. It rendered a loud fan completely silent during one of my tests. However, that processing impacts overall clarity, so you won’t sound nearly as good as you do in quieter locations. Plus, the results in noiseless conditions aren’t pristine, but it’s good enough to get the job done for most call scenarios.
Sony brought back the convenient automation features that have made its flagship headphones the best option for years. Adaptive Sound Control can automatically adjust settings based on activity or location, like when you arrive at the office or when you’re out for a walk. Ambient sound still has pleasant, natural quality and is helpful to have on during calls. Speak-to-Chat continues to reduce the volume and activates that transparency mode when it detects your voice, though it’s still far too easily duped by coughs and when you clear your throat. You can also use head gestures to accept (nod) or reject calls (shake). There’s plenty more, but suffice it to say Sony is still ahead of the pack for the sheer volume of features it packs into its 1000X headphones.
Battery life
One of the few things that’s unchanged on the WH-1000XM6 is battery life. Just like the M5, this model offers up to 30 hours of use with ANC on or up to 40 hours with it off. The quick charge function is also the same: three minutes gives you three hours. I had no problem hitting these stated figures during my tests, which were primarily conducted with ANC on as well as Sony’s DSEE Extreme audio upscaling enabled. I would occasionally switch to transparency mode for calls, but 80 percent of the time I was in noise-blocking mode. After 25 hours of use, I still have 50 percent left in the tank.
There is one item Sony tweaked when it comes to battery and charging performance. On the M6, you’ll be able to listen to music while the headphones are charging. This functionality wasn’t available previously, and it’s sure to provide some added convenience in a pinch — like when you’re waiting for your flight in a raucous airport terminal.
The competition
Whether it’s Bose, Bowers & Wilkins or Sennheiser, there are a number of companies that inch closer to Sony’s crown with each product cycle. I’m convinced Sony has surpassed Bose in terms of pure noise-cancelling performance, but the QuietComfort Ultra headphones are still plenty good and can regularly be found for less than their $449 suggested retail price. I don’t care for the design of Sennheiser’s Momentum Wireless 4, but the headphones have nearly double the battery life of the M6 with plenty of audio and ANC performance to boot. And they do so for less money than the WH-1000XM6.
This leads me to the Bowers & Wilkins Px7 S3. The company’s Px7 S2e had been my pick for best sounding headphones for a while, and were only recently bested by Noble Audio’s pricey FoKus Apollo ($649). The S3 edition supposedly offers improvements to sound and ANC performance, but I haven’t tested them yet and there’s no clear indication how much they’ll cost or when they’ll arrive. Still, if you’re not in a hurry, the Px7 S3 may be worth waiting on as they should be slightly more affordable than the M6 and Bowers & Wilkins has a strong track record for sound quality.
Wrap-up
With the WH-1000XM6, the three-year-long wait was well worth it. The company has made significant gains in both sound quality and noise-canceling performance, thanks in part to a powerful new chip. Subtle, but impactful design tweaks increase comfort, while spatial audio upmixing further expands the sonic abilities of the 1000X line. The only real downside is the price continues to go up: the M6 is $50 more than the M5 was at launch. When you combine their performance with Sony’s ever-growing list of features, the 1000XM6 are the best headphones you can buy right now.
