Is the OnePlus Buds Pro 4 worth the upgrade from the Xiaomi Redmi Buds 3?
Verdict
Clear upgrade
Going from the Xiaomi Redmi Buds 3 to the OnePlus Buds Pro 4 buys you 24.1 points of HearWiki score - a clear step up that reviewers agree on rather than a marketing refresh. The gains are concentrated in sound (5.5 to 8.5), calls (5.0 to 7.5) and battery (6.5 to 8.5). On paper: battery life 5 h to 13 h, active noise cancelling and bluetooth 5.2 to 5.4. Worth checking: driver size goes 12 mm to 11 mm. That costs $110 more, or about $5 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.
