Is the Technics EAH-AZ100 worth the upgrade from the Sennheiser MOMENTUM True Wireless?
Verdict
Clear upgrade
Going from the Sennheiser MOMENTUM True Wireless to the Technics EAH-AZ100 buys you 24.9 points of HearWiki score - a clear step up that reviewers agree on rather than a marketing refresh. The gains are concentrated in battery (5.0 to 8.7), sound (7.5 to 9.2) and value (6.5 to 8.1). On paper: battery life 4 h to 12 h, active noise cancelling and weight 17 g to 11.8 g. Worth checking: full charge time goes 90 min to 120 min. That costs $70 more, or about $3 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.
