Is the Audio-Technica ATH-SR50BT worth the upgrade from the Earfun Wave Pro X?
Verdict
Downgrade
The Audio-Technica ATH-SR50BT actually scores 29.8 points below the Earfun Wave Pro X, so on aggregate review consensus this is a step backwards. It loses ground on noise cancelling (7.8 to 3.2) and battery (9.5 to 5.2). On paper: driver size 40 mm to 45 mm and drivers per side 1 to 2. Worth checking: battery life goes 90 h to 28 h and active noise cancelling goes Yes to No. One caution: this steps down a line tier (Wave Pro X to ATH-SR50BT), and base models usually trade away tier features - check the codec and ANC rows above before trusting the score gap alone. It is at least $10 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.

About this verdict
Direction matters here: this page answers "Wave Pro X to ATH-SR50BT". The other direction is a separate question with a different answer. Scores blend published review verdicts across over-ear and shift as new reviews land, so a marginal call today may not be one next quarter.
