Is the Technics EAH-AZ100 worth the upgrade from the Huawei FreeBuds 3?
Verdict
Clear upgrade
Going from the Huawei FreeBuds 3 to the Technics EAH-AZ100 buys you 38.8 points of HearWiki score - a clear step up that reviewers agree on rather than a marketing refresh. The gains are concentrated in value (2.2 to 8.1), battery (3.4 to 8.7) and noise cancelling (3.5 to 8.6). On paper: battery life 4 h to 12 h, codecs SBC, AAC to SBC, AAC, LC3, LDAC and bluetooth 5.1 to 5.3. Worth checking: weight goes 4.5 g to 11.8 g and full charge time goes 60 min to 120 min. That costs $42 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.
