Sony WF-1000XM6 review: small, smart, and finally fitting properly

After two generations of fit complaints, Sony has fixed the WF line. The XM6 are the most usable flagship earbuds Sony has shipped.

Overview

Sony’s WF-1000 line has been the technical class leader in true-wireless ANC since the XM3 in 2019. It has also been, since the XM4, hampered by a single recurring issue: the shell was too big, the fit was inconsistent, and a meaningful share of buyers — including one reviewer on this team — could not get a stable seal in either ear. We tracked the problem across the XM4 and XM5 generations, and we wrote in our XM5 review in 2024 that “Sony’s tech keeps improving while a non-trivial fraction of customers cannot benefit from it.”

The XM6 is Sony’s response. Same flagship-tier internals, different shell.

Key features tested

The XM6 keep the V2 processor from the XM5 generation but pair it with a redesigned acoustic chamber. Sony has reduced the shell volume by approximately twelve percent — small on paper, meaningful in practice — and changed the angle at which the nozzle exits the body. The result is a shell that sits flusher to the concha and protrudes less from the ear canal opening.

Codec support is the expected Sony loadout: SBC, AAC, LDAC, and (new on the XM6) LC3 for Bluetooth Low Energy Audio, including Auracast broadcast reception. ANC is upgraded with a new feed-forward microphone array; transparency mode uses the same hardware path but with revised processing.

Battery is rated at 8 hours with ANC, 12 with ANC off. The case adds three additional charges. The case supports Qi wireless charging (slowly) and USB-C (fast).

Performance over six weeks

For ANC measurements we used the same MiniDSP EARS rig and pink-noise reference as in our Bose QuietComfort Ultra 2 review. For true wireless testing, we used a coupler with the manufacturer’s largest tip that achieved a stable seal.

ANC averaged -25 dB across 50-200 Hz, -19 dB across 200-1000 Hz, and -11 dB across 1-4 kHz. This is roughly a 2-3 dB improvement on the XM5, and it puts the XM6 inside spitting distance of the AirPods Pro 3 across most of the audible range. We are now in a category where flagship true-wireless ANC is a settled question — the differences between the top three or four products are small enough that fit, codec, and ecosystem matter more.

Transparency mode, on the other hand, is genuinely the best we’ve measured in true wireless. Sony has tuned the processing to minimise the “tunnel” feeling — the slight echo characteristic of poor transparency implementations — and the result is convincing enough that one reviewer used it for a 30-minute conversation without removing the buds. AirPods Pro 3 still hold a slight edge in noise floor, but Sony has closed the gap meaningfully.

LDAC remains our preferred codec for Android playback. We measured a stable 990 kbps connection at three meters in a busy 5 GHz environment, which is rare. The XM5 used to drop to 660 kbps under similar conditions.

Strengths

The fit revision is the headline. Both reviewers achieved a stable seal in both ears with the medium silicone tip on the XM6, where one reviewer had been unable to do so on the XM5. The new shape also reduces the visual protrusion from the ear, which matters for buyers who didn’t like how prominent the XM5 looked in mirror.

Codec support is comprehensive. LDAC works as advertised. LC3 over LE Audio is functional, and Auracast broadcast reception is the first we’ve tested in earbuds at this price tier — useful as more public spaces (gyms, gates, bars) deploy Auracast transmitters.

Multi-point with two devices is reliable. Switching between a Pixel and a MacBook over six weeks of testing produced one connection failure, recovered with a single tap.

Weaknesses

The touch surface is the main usability complaint. Both reviewers triggered accidental track skips when adjusting glasses, scratching an ear, or wearing a hat. Sony offers customisation in the app, but the only way to disable touch controls is to disable them entirely. A “press and hold to lock” gesture would help.

The companion app continues to push promotional content into a paid product. We do not need a “Listening Profile” tutorial or a “New scene available” push notification on a $299 set of earbuds.

Wireless charging is slow. With a Qi 1.3 pad we measured 1.5 hours from empty to full, against 45 minutes for USB-C. The case markings imply parity, which they don’t deliver.

Foam tips are not included. We strongly recommend buyers budget for Comply Sport Pro or Azla Sednafit replacement tips — the included silicone tips are fine, but for long sessions or active use, foam dramatically improves both seal and comfort.

Verdict

The XM6 are the most usable flagship Sony earbuds we’ve tested. They don’t beat the AirPods Pro 3 for iOS users, and they don’t beat the QuietComfort Ultra 2 for outright comfort. They do have the best transparency mode in the segment, the best codec support for Android, and a fit that no longer fails for a meaningful fraction of users. For Android-first buyers, they’re our default recommendation in the category.
