Is the Sony WF-1000XM6 worth the upgrade from the Sony WF-1000XM4?
Verdict
Marginal upgrade
There's only 4.0 points between the Sony WF-1000XM4 and the Sony WF-1000XM6. That's inside the range where two reviewers might simply disagree. The gains are concentrated in calls (7.0 to 8.0), sound (8.5 to 9.0) and battery (7.5 to 8.0). You do give up ground on value (7.5 to 7.0). On paper: codecs SBC, AAC, LDAC to SBC, AAC, LDAC, LC3, bluetooth 5.2 to 5.3 and driver size 6 mm to 8.4 mm. Worth checking: case weight goes 41 g to 47 g. That costs $99 more, or about $25 per point of score - reasonable value for the jump. Keep what you have unless a specific feature above is the thing you're missing - the overall quality gap won't be what convinces you.
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 "WF-1000XM4 to WF-1000XM6". The other direction is a separate question with a different answer. Scores blend published review verdicts across true wireless and shift as new reviews land, so a marginal call today may not be one next quarter.
