Is the OnePlus Buds Pro 4 worth the upgrade from the Nothing Ear (a)?
Verdict
Meaningful upgrade
The OnePlus Buds Pro 4 scores 6.0 points above the Nothing Ear (a). That's a real improvement, though not the kind you'd notice on every track. The gains are concentrated in sound (8.0 to 8.5), noise cancelling (7.5 to 8.0) and value (8.5 to 9.0). You do give up ground on calls (8.0 to 7.5). On paper: battery life 9.5 h to 13 h, bluetooth 5.3 to 5.4 and battery life (anc on) 5.5 h to 7 h. Worth checking: drivers per side goes 2 to 1 and case weight goes 39.6 g to 50.62 g. That costs $50 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.

About this verdict
Direction matters here: this page answers "Ear (a) 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.
