Is the OnePlus Buds 4 worth the upgrade from the Xiaomi Redmi Buds 4 Pro?

Verdict

Clear upgrade

Going from the Xiaomi Redmi Buds 4 Pro to the OnePlus Buds 4 buys you 13.9 points of HearWiki score - a clear step up that reviewers agree on rather than a marketing refresh. The gains are concentrated in noise cancelling (6.0 to 8.4), calls (6.5 to 8.0) and sound (7.5 to 8.8). You do give up ground on battery (7.5 to 6.3). On paper: battery life 9 h to 11 h, bluetooth 5.3 to 5.4 and battery incl. case 36 h to 45 h. Worth checking: case weight goes 39.5 g to 50.6 g and wear detection goes Yes to No. One caution: this steps down a line tier (Redmi Buds 4 Pro to Buds 4), and base models usually trade away tier features - check the codec and ANC rows above before trusting the score gap alone. That costs $58 more, or about $4 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.
