Is the Sony WF-1000XM6 worth the upgrade from the Huawei FreeBuds 4?
Verdict
Clear upgrade
Going from the Huawei FreeBuds 4 to the Sony WF-1000XM6 buys you 22.0 points of HearWiki score - a clear step up that reviewers agree on rather than a marketing refresh. The gains are concentrated in noise cancelling (5.0 to 9.0), sound (6.5 to 9.0) and battery (5.5 to 8.0). On paper: battery life 4 h to 12 h, codecs SBC, AAC to SBC, AAC, LDAC, LC3 and bluetooth BT 5.2 to 5.3. Worth checking: full charge time goes 60 min to 90 min and driver size goes 14.3 mm to 8.4 mm. That costs $143 more, or about $7 per point of score - reasonable value for the jump. If your current pair is worn out or the gains line up with how you listen, this one is worth the money.
What actually changes
