Is the Sennheiser HD 400 worth the upgrade from the JBL Live 780NC?
Verdict
Meaningful upgrade
The Sennheiser HD 400 scores 8.0 points above the JBL Live 780NC. That's a real improvement, though not the kind you'd notice on every track. The gains are concentrated in value (7.5 to 8.3). You do give up ground on calls (6.5 to 4.9). On paper: weight 260 g to 240 g. Worth checking: active noise cancelling goes Yes to No and multipoint pairing goes Yes to No. It's also $130 cheaper, which makes this an easy call. Worth doing if you're replacing anyway; harder to justify as a pure upgrade if what you have still works.
What actually changes
Sub-scores both products have, on the same 0-10 scale. Bars extend right for a gain, left for a loss.
