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.
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).
