Is the OnePlus Buds Pro 4 worth the upgrade from the Xiaomi Redmi Buds 6?
Verdict
Clear upgrade
Going from the Xiaomi Redmi Buds 6 to the OnePlus Buds Pro 4 buys you 10.3 points of HearWiki score - a clear step up that reviewers agree on rather than a marketing refresh. The gains are concentrated in sound (7.5 to 8.5), noise cancelling (7.0 to 8.0) and calls (6.5 to 7.5). On paper: battery life 10 h to 13 h, codecs SBC, AAC to SBC, AAC, LHDC and battery incl. case 42 h to 54 h. Worth checking: driver size goes 12.4 mm to 11 mm and drivers per side goes 2 to 1. That costs $102 more, or about $10 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
Sub-scores both products have, on the same 0-10 scale. Bars extend right for a gain, left for a loss.
