Is the Apple AirPods Pro (2nd Gen, USB-C) worth the upgrade from the Technics EAH-AZ40?
Verdict
Clear upgrade
Going from the Technics EAH-AZ40 to the Apple AirPods Pro (2nd Gen, USB-C) buys you 16.0 points of HearWiki score - a clear step up that reviewers agree on rather than a marketing refresh. The gains are concentrated in sound (7.0 to 8.5), calls (7.0 to 8.0) and battery (7.0 to 7.5). On paper: bluetooth 5.2 to 5.3, battery incl. case 25 h to 30 h and driver size 6 mm to 11 mm. Worth checking: weight goes 5 g to 10.6 g and multipoint pairing goes Yes to No. The two sit at effectively the same price. 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.
