## What reviewers say

**Sony WH-1000XM6** — Three whitelisted testers (SoundGuys, What Hi-Fi, Tom's Guide) rate the WH-1000XM6 a strong flagship. SoundGuys (5-day test) logged 37 hours 14 minutes of battery with ANC and a 4.8/5 MDAQS score, praising excellent ANC, sound and microphone but flagging thin pads and no USB-C audio. What Hi-Fi (Awards 2025 winner, five stars) calls it the best-sounding Sony flagship with class-leading calls and rates comfort a full 5/5. Tom's Guide's 3-months-later follow-up is the outlier, judging the Bowers & Wilkins PX7 S3 better-sounding and the Bose QC Ultra better at blocking noise, and calling the build cheap-feeling for $449. Reviewers split on comfort, value and how much the XM6 improves on the XM5. (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.)
