## What reviewers say

**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.)

**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.)
