Is the JBL Live 780NC worth the upgrade from the Sennheiser HD 400?
Verdict
Downgrade
The JBL Live 780NC actually scores 8.0 points below the Sennheiser HD 400, so on aggregate review consensus this is a step backwards. The gains are concentrated in calls (4.9 to 6.5). You do give up ground on value (8.3 to 7.5). On paper: active noise cancelling, multipoint pairing and microphones 1 to 4. Worth checking: weight goes 240 g to 260 g. And it costs $130 more for a lower score, which is hard to justify on the data alone. Only worth it if a specific feature above matters more to you than overall quality does.
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 "HD 400 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.
