Is the Audeze Maxwell 2 worth the upgrade from the Audio-Technica ATH-SR50BT?
Verdict
Clear upgrade
Going from the Audio-Technica ATH-SR50BT to the Audeze Maxwell 2 buys you 30.4 points of HearWiki score - a clear step up that reviewers agree on rather than a marketing refresh. The gains are concentrated in calls (4.2 to 9.0), battery (5.2 to 9.5) and sound (7.4 to 9.5). On paper: battery life 28 h to 80 h, active noise cancelling and bluetooth 5.0 to 5.3. Worth checking: weight goes 262 g to 560 g and drivers per side goes 2 to 1. That costs $209 more, or about $7 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.

About this verdict
Direction matters here: this page answers "ATH-SR50BT to Maxwell 2". 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.
