## What reviewers say

**Bose QuietComfort Ultra Headphones** — Three whitelisted testers (SoundGuys, Tom's Guide, What Hi-Fi) reviewed the original 2023 QC Ultra Headphones. All three rate the ANC best-in-class, comfort excellent and sound entertaining, while flagging the $429 price. SoundGuys measured 27h37m runtime and ~87% real-world noise reduction and praised battery; Tom's Guide and What Hi-Fi call the 24h battery only decent, not class-leading. Immersive Audio splits opinion. (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.)
