What reviewers say
Sourced tester consensus for each — the "what people who used it think" layer, not just specs.
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.
Beyerdynamic Aventho 300
Two whitelisted testers reviewed the exact Aventho 300: SoundGuys (lab-measured, 6.7/10) and What Hi-Fi (hands-on, 4/5 stars). Both praise the long 50-plus-hour battery, the build and the feature set, and both flag mediocre ANC that trails class leaders like Bose. They diverge on sound: SoundGuys measures over-emphasized bass and harsh treble and gives a poor 2.5/5 MDAQS score, while What Hi-Fi hears a clean, even-handed signature that simply lacks the dynamism of rivals like the Dali IO-8. SoundGuys is far harsher on value and comfort; What Hi-Fi calls them solid performers for the money. No other whitelisted outlet had a fetchable review. (2 sourced reviews, 1 lab-tested.)
Praised: Exceptional battery life (50-plus hours rated, ~65h measured with ANC) plus fast charging; Premium build quality with foldable metal frame/hinges (SoundGuys also praises the hardcover case); Strong connectivity and features: Bluetooth 5.4, aptX Lossless/Adaptive, multipoint, Dolby Atmos, custom EQ.
Flagged: Mediocre ANC that trails class leaders like Bose; Sound isn't class-leading: SoundGuys flags over-emphasized bass and harsh treble (2.5/5 MDAQS), What Hi-Fi finds less dynamic contrast than the Dali IO-8; Comfort issues from the 319g weight, stiff pads, clamping force and heat build-up (SoundGuys).
