## What reviewers say

**Sony WH-1000XM6** — Three whitelisted testers (SoundGuys, What Hi-Fi, Tom's Guide) rate the WH-1000XM6 a strong flagship. SoundGuys (5-day test) logged 37 hours 14 minutes of battery with ANC and a 4.8/5 MDAQS score, praising excellent ANC, sound and microphone but flagging thin pads and no USB-C audio. What Hi-Fi (Awards 2025 winner, five stars) calls it the best-sounding Sony flagship with class-leading calls and rates comfort a full 5/5. Tom's Guide's 3-months-later follow-up is the outlier, judging the Bowers & Wilkins PX7 S3 better-sounding and the Bose QC Ultra better at blocking noise, and calling the build cheap-feeling for $449. Reviewers split on comfort, value and how much the XM6 improves on the XM5. (3 sourced reviews.)

**Bowers & Wilkins Px7 S3** — All four whitelisted reviews of the exact Px7 S3 (SoundGuys, What Hi-Fi, TechRadar, Engadget) survived verification; every quote and the single measured figure were confirmed as literal text, none dropped. All four praise the premium build and comfortable, lighter 300g fit, and all agree the reworked ANC is improved but still trails Bose. Only SoundGuys published lab data (an average 83-84% reduction in perceived loudness); the other three are qualitative listening reviews. (4 sourced reviews.)
