Is the JBL Live 780NC worth the upgrade from the JBL Live 770NC?
Verdict
Marginal upgrade
There's only 3.4 points between the JBL Live 770NC and the JBL Live 780NC. That's inside the range where two reviewers might simply disagree. The gains are concentrated in sound (7.0 to 7.5). You do give up ground on noise cancelling (7.5 to 7.0) and calls (7.0 to 6.5). On paper: battery life 50 h to 80 h, codecs SBC to SBC, AAC, LDAC and bluetooth 5.3 to 6.0. Worth checking: weight goes 232 g to 260 g. That costs $50 more, or about $15 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 "Live 770NC to Live 780NC". 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.
