What reviewers say
Sourced tester consensus for each — the "what people who used it think" layer, not just specs.
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, 1 lab-tested.)
Praised: Class-leading active noise cancelling; Comfortable, lightweight foldable design; Rich, entertaining sound quality.
Flagged: High $429 price versus rivals; Only-decent 24h battery, not class-leading; No USB-C wired audio listening.
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, 1 lab-tested.)
Praised: Premium build quality and refined, handsome design; Comfortable, lighter 300g fit; Detailed, dynamic and entertaining sound quality.
Flagged: ANC improved but still not class-leading; trails Bose; Limited/basic feature set; spatial audio missing at launch; Price has crept upward / expensive for the category.
