Is the Sony WH-1000XM6 worth the upgrade from the JBL Live 770NC?
Verdict
Clear upgrade
Going from the JBL Live 770NC to the Sony WH-1000XM6 buys you 21.6 points of HearWiki score - a clear step up that reviewers agree on rather than a marketing refresh. The gains are concentrated in calls (7.0 to 9.6), noise cancelling (7.5 to 9.6) and sound (7.0 to 9.0). You do give up ground on battery (9.0 to 8.1). On paper: codecs SBC to SBC, AAC, LC3, LDAC, microphones 4 to 12 and detachable cable. Worth checking: battery life goes 50 h to 40 h and weight goes 232 g to 254 g. That costs $248 more, or about $11 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 "Live 770NC 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.
