Is the Sennheiser MOMENTUM True Wireless worth the upgrade from the Technics EAH-AZ100?
Verdict
Downgrade
The Sennheiser MOMENTUM True Wireless actually scores 24.9 points below the Technics EAH-AZ100, so on aggregate review consensus this is a step backwards. It loses ground on battery (8.7 to 5.0) and sound (9.2 to 7.5). On paper: full charge time 120 min to 90 min. Worth checking: battery life goes 12 h to 4 h and active noise cancelling goes Yes to No. It is at least $70 cheaper, so the lower score comes with a saving. Only worth it if a specific feature above matters more to you than overall quality does.
What actually changes
Sub-scores both products have, on the same 0-10 scale. Bars extend right for a gain, left for a loss.
