Sony WH-1000XM6 Review: The Flagship Finally Folds Again
Sony's WH-1000XM6 brings back the folding hinge, adds the QN3 processor and 12 microphones, and fixes the call quality that held the XM5 back. Here's what changed and who should upgrade.
Sony has owned the noise-cancelling category for so long that each new model arrives with a strange burden: it has to justify replacing something that already worked. The WH-1000XM6 does that in a way the XM5 did not, and the most important change is one nobody demoed on stage — the headphones fold up again.
This is a researched buying guide rather than a hands-on test. Everything below is drawn from the published specification and from what independent measurement sites and long-term owners consistently report, with sources at the end. Where reviewers disagree, we say so.
Who the XM6 is actually for
Three groups get real value here, and it is worth knowing which one you are in before spending flagship money.
People who fly or commute often. This is the core case and always has been. Sustained low-frequency noise — jet engines, train carriages, the drone of an open-plan office air handler — is what active noise cancellation removes best, and the XM6 removes more of it than almost anything else on sale.
People who take calls all day. This is the genuinely new argument. Multiple independent reviews single out call quality as the XM6’s standout improvement, which historically was the one area where Sony lost to Bose and to dedicated headsets. If you work remotely and live on video calls, that matters more than another decibel of isolation.
People who want one pair for everything. Wired 3.5 mm, USB-C, multipoint Bluetooth, and now a folding hinge. It is a single pair that covers a desk, a flight and a walk without compromise.
If you mostly listen at a desk in a quiet room, you are paying a large premium for cancellation you will not use. A wired pair at half the price will sound better for the money.
The folding hinge is not a small detail
The XM5 dropped the folding design in favour of a slimmer headband, and it was the single most complained-about change in the range’s history. The case grew, the headphones stopped fitting in a bag pocket, and a product built for travel became worse at travelling.
The XM6 folds again. If you own the XM5 and have been irritated by the case every time you packed it, that alone may be the upgrade — not the audio.
Sound, honestly described
Sony tunes for a broad audience, which means a modest bass lift and a smooth, forgiving treble. It is not a neutral reference tuning and it is not trying to be. If you want flat response for mixing, this is the wrong purchase and always has been.
The new 40 mm driver uses a redesigned diaphragm aimed specifically at distortion at high volume — the point where previous models started to lose composure. In practice that means the XM6 holds together when you push it, which matters on a plane where you are fighting cabin noise with volume.
Worth knowing: almost every complaint about Sony’s tuning is fixable in the app’s equaliser, and almost nobody opens it. If you find the bass heavy, five minutes in the EQ will change your opinion of these headphones more than any firmware update.
Noise cancellation and the QN3 processor
The headline change is the HD NC Processor QN3 working across twelve microphones, with adaptive optimisation that adjusts to your surroundings and to the seal your head and glasses actually make.
Two caveats sit behind every ANC claim, and they apply to every brand:
- Low frequencies cancel well; voices do not. Cancellation is far better at engine drone than at the conversation two desks away. If your problem is chatter, you are buying isolation and masking, not silence.
- Fit determines everything. Glasses break the seal. So do earrings, thick hair and hats. Reviewers measuring in a lab get a better result than most people wearing them in real life.
Battery life you can plan around
Sony rates the XM6 at 30 hours with ANC on. Owners report landing between roughly 28 and 31 hours depending on how hard the cancellation is working and how loud you listen — which is unusually close to the official figure. Many manufacturers quote a number nobody reaches.
Practically: that is a full working week of a two-hour daily commute, or a return long-haul flight with room to spare. Charge it on Sunday and stop thinking about it.
How it compares with the obvious alternatives
Three headphones come up in every shortlist at this price. They are genuinely different products, not the same thing in different colours.
| Model | Strongest at | Weakest at | Choose it if |
|---|---|---|---|
| Sony WH-1000XM6 | Overall package, call quality, app control | Not a neutral tuning | You want one pair that does everything well |
| Bose QuietComfort Ultra | Comfort over long wear, cancellation | Less app control, less customisable | Comfort matters more than features |
| Apple AirPods Max | Apple ecosystem, build materials | Weight, price, charging case design | You live entirely inside Apple’s ecosystem |
If you want the in-ear version of this decision instead, we cover it in our look at the Bose QuietComfort Ultra Earbuds and the AirPods Pro 3.
What it does well
- Class-leading cancellation on steady low-frequency noise
- Call quality that reviewers repeatedly single out as best in class
- Rated battery life that owners actually reach
- Folds again, so the case fits in a bag
- Wired 3.5 mm and USB-C both retained
What to think about first
- Flagship price for capability you may not use at a desk
- Tuning is deliberately consumer-friendly, not neutral
- Glasses noticeably reduce real-world cancellation
- The XM5 is still excellent and now cheaper
- No cancellation handles speech well — including this one
Should you upgrade from the XM4 or XM5?
From the XM4: yes, if cancellation and calls matter to you. Two generations of processor and microphone work is a real gap, not a marketing one.
From the XM5: only for the folding hinge and the call quality. The audio difference is not large enough on its own to justify replacing a working pair, and we would rather tell you that than sell you an upgrade.

The verdict
The XM6 is the most complete wireless headphone you can buy, and the call quality improvement is the reason to care rather than the audio. Buy it if you travel, commute or take calls all day. If you sit in a quiet room and want the best sound per pound, spend less and buy something wired.
