Is the JBL Live 770NC worth the upgrade from the JBL Live 780NC?
Verdict
Downgrade
The JBL Live 770NC actually scores 3.4 points below the JBL Live 780NC, so on aggregate review consensus this is a step backwards. The gains are concentrated in noise cancelling (7.0 to 7.5), calls (6.5 to 7.0) and value (7.5 to 8.0). You do give up ground on sound (7.5 to 7.0). On paper: weight 260 g to 232 g. Worth checking: battery life goes 80 h to 50 h and codecs goes SBC, AAC, LDAC to SBC. It is at least $50 cheaper, so the lower score comes with a saving. 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.
