What reviewers say
Sourced tester consensus for each — the "what people who used it think" layer, not just specs.
Sennheiser Momentum 4 Wireless
Four whitelisted testers (SoundGuys, Engadget, Tom's Guide, What Hi-Fi) rate the Momentum 4 Wireless a top-value ANC over-ear: class-leading battery life and refined, neutral sound draw praise, though ANC trails Bose/Sony flagships and the restyle looks generic. SoundGuys lab-measured 56h21m of playback with ANC on; Engadget clocked 57h at ~75% volume. All four quotes and both measured battery figures were confirmed verbatim in the fetched pages. (4 sourced reviews, 2 lab-tested.)
Praised: Exceptional, class-leading battery life (far beyond ~30h rivals); Refined, balanced, neutral sound quality; Comfortable, lightweight fit with plush padding.
Flagged: ANC is effective but trails Bose/Sony flagships; Generic, anonymous restyle drops the classy older Momentum aesthetic; Buggy/unreliable Smart Control app connectivity.
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.
