## 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.)

**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.)
