Is the Technics EAH-AZ100 worth the upgrade from the OnePlus Buds 3?
Verdict
Clear upgrade
Going from the OnePlus Buds 3 to the Technics EAH-AZ100 buys you 11.9 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 8.6), battery (7.0 to 8.7) and sound (8.0 to 9.2). On paper: battery life 10 h to 12 h, battery life (anc on) 6.5 h to 10 h and wireless charging. Worth checking: weight goes 4.8 g to 11.8 g and battery incl. case goes 44 h to 28 h. That costs $152 more, or about $13 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 3 to EAH-AZ100". 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.
