Is the OnePlus Buds Pro 4 worth the upgrade from the Xiaomi Redmi Buds 6 Pro?
Verdict
Meaningful upgrade
The OnePlus Buds Pro 4 scores 6.0 points above the Xiaomi Redmi Buds 6 Pro. That's a real improvement, though not the kind you'd notice on every track. The gains are concentrated in calls (6.0 to 7.5), sound (8.0 to 8.5) and noise cancelling (7.5 to 8.0). On paper: battery life 9.5 h to 13 h, bluetooth 5.3 to 5.4 and battery incl. case 36 h to 45 h. Worth checking: latency goes 20 ms to 47 ms and drivers per side goes 3 to 1. That costs $47 more, or about $8 per point of score - reasonable value for the jump. Worth doing if you're replacing anyway; harder to justify as a pure upgrade if what you have still works.
What actually changes
Sub-scores both products have, on the same 0-10 scale. Bars extend right for a gain, left for a loss.

About this verdict
Direction matters here: this page answers "Redmi Buds 6 Pro to Buds Pro 4". The other direction is a separate question with a different answer. Scores blend published review verdicts across true wireless and shift as new reviews land, so a marginal call today may not be one next quarter.
