Is the Sony WH-1000XM6 worth the upgrade from the Shure Srh840a?
Verdict
Clear upgrade
Going from the Shure Srh840a to the Sony WH-1000XM6 buys you 17.3 points of HearWiki score - a clear step up that reviewers agree on rather than a marketing refresh. The gains are concentrated in sound (8.0 to 9.0) and value (7.5 to 8.2). On paper: active noise cancelling, weight 273 g to 254 g and usb-c. Worth checking: driver size goes 40 mm to 30 mm. That costs $229 more, or about $13 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 "Srh840a to WH-1000XM6". 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.
