Sony Put the Hinges Back: Inside the WH-1000XM6
Sony announced the WH-1000XM6 on 15 May 2025 at £400, a rise of roughly £50 over the model it replaced. The headline changes are structural rather than sonic: folding hinges return after the XM5 abandoned them, the headband is wider and flatter, and the case now opens on a magnetic clasp. Underneath sits a QN3 processor that Sony describes as seven times faster than the QN1 used in the XM5, feeding twelve microphones. What Hi-Fi awarded five stars and named them among its 2025 Award winners. The reservations are narrower than they used to be, but they are still there.
Manufacturer and reviewer figures, attributed
- Price: £400 in the UK, 450 US dollars, announced 15 May 2025
- Weight: 254g, as measured by What Hi-Fi
- Battery: 30 hours with Bluetooth and noise cancelling active, per Sony, unchanged from the XM5
- Drivers: 30mm units with a carbon fibre composite dome and a redesigned voice coil
- Codecs: SBC, AAC, LDAC and LC3; no aptX HD
The QN3 processor and the twelve-microphone array
Sony’s stated figure is that the QN3 runs seven times faster than the QN1 fitted to the XM5, and that it is fed by twelve microphones rather than the eight of the previous generation. Those are manufacturer claims about internal architecture, and there is no meaningful way for a listener to verify a processing speed multiplier by ear. What can be assessed is the result, and What Hi-Fi’s review described the isolation as extremely well handled and wonderfully consistent, with a particular strength in bass and midrange rejection and an approach it characterised as more natural and subtle than rivals.
The microphone count is doing double duty. Beyond cancellation, the extra capsules feed call processing, and this is where generational gains in the category have been most visible over the past few years. Wind handling on the move remains the weakest scenario for every product in this class, Sony’s included.
Sony’s driver specification is a 30mm unit with a carbon fibre composite dome and a redesigned voice coil structure, alongside DSEE Extreme upscaling and 360 Reality Audio with a new cinema upmix mode. What Hi-Fi’s assessment of the result was unusually strong for a Sony flagship, describing the most detailed, dynamic, precise and open sound the range has produced and calling the overall performance sensational.
Folding returns, and the clamping force went up
The XM5 removed the folding hinge in favour of a swivel-only design and a case that took up considerably more bag space. The XM6 restores hinges, and What Hi-Fi’s review confirms the earcups fold into a compact shape once more. The headband is wider and flatter, the earcups have a seamless, rounder profile, and the power button is now circular and recessed so it can be found without looking.
Sony also increased clamping force, which is presented as an isolation improvement and functions as one. It is also the change most likely to cause problems for a minority of wearers. Anyone who wears glasses, or who has previously found Sony’s pads uncomfortable over long sessions, should treat the tighter fit as something to try rather than assume.
Thirty hours, for the fourth generation running
Sony’s rating remains 30 hours with Bluetooth and noise cancelling enabled, exactly as quoted for the XM5 and the XM4 before it. That is a perfectly usable figure and it has not improved in years, while the competition has generally been creeping upwards. For a product that has raised its price across the same period, a static endurance specification is a fair thing to note.
In practice, 30 hours means most people charge weekly rather than daily, and quick-charge support covers the case of discovering a flat battery at an airport gate. The number is adequate. It is simply not a reason to upgrade.
The wider point is that Sony’s flagship over-ears have settled into an incremental pattern. Each generation refines tuning and processing while the fundamentals, the endurance figure and the codec list among them, stay where they were. That is what a mature product line looks like, and it is also why the upgrade case gets weaker with every release.
The omissions that have not been addressed
- No aptX HD support, which matters to Android users on devices where LDAC is unavailable or unstable
- No wired audio over the USB-C connection, so the supplied analogue cable is the only wired route
- A case that What Hi-Fi still describes as on the large side, despite the folding redesign
- A finish prone to showing fingerprints, which the same review suggests means regular case storage
Whether £400 is defensible in 2026
The competitive position has shifted since May 2025. Rivals have launched, discounted and been discounted again, and the XM6 itself has appeared in sales below list. Buying at full price makes sense principally for people who want Sony’s specific tuning and its app ecosystem, including the adaptive sound control and the multipoint behaviour that has historically been more reliable than most.
For anyone upgrading from an XM5, the argument is thinner. The sound is better and the folding hinge is a genuine convenience, but the battery is identical, the codec support is unchanged and the noise cancelling improvement is a refinement of something that was already excellent. For anyone coming from an XM4 or older, or from a different brand entirely, the five-star reception is well earned.
One thing that is not in doubt is that Sony has fixed the specific mistake the XM5 made. Removing the folding hinge in 2022 was widely criticised at the time and the case that resulted was awkward to pack. Restoring it, while keeping the improved sound and adding the wider headband, addresses the loudest complaint about the previous model without giving anything up in return.
