Is the Realme Buds Air8 Pro worth the upgrade from the OnePlus Buds Z?
Verdict
Clear upgrade
Going from the OnePlus Buds Z to the Realme Buds Air8 Pro buys you 21.0 points of HearWiki score - a clear step up that reviewers agree on rather than a marketing refresh. The gains are concentrated in calls (6.0 to 8.5), sound (6.0 to 8.4) and value (7.5 to 9.2). On paper: battery life 5 h to 12 h, active noise cancelling and codecs SBC, AAC to SBC, AAC, LHDC. Worth checking: case weight goes 40 g to 53 g. That costs $24 more, or about $1 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.

About this verdict
Direction matters here: this page answers "Buds Z to Buds Air8 Pro". 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.
