Is the Audio-Technica ATH-SR50BT worth the upgrade from the AKG N9 Hybrid?
Verdict
Downgrade
The Audio-Technica ATH-SR50BT actually scores 27.7 points below the AKG N9 Hybrid, so on aggregate review consensus this is a step backwards. It loses ground on noise cancelling (8.4 to 3.2) and calls (9.1 to 4.2). On paper: weight 281 g to 262 g, driver size 40 mm to 45 mm and drivers per side 1 to 2. Worth checking: battery life goes 100 h to 28 h and active noise cancelling goes Yes to No. It is at least $169 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.
