Is the JBL Live 770NC worth the upgrade from the Sony WH-1000XM6?
Verdict
Downgrade
The JBL Live 770NC actually scores 21.6 points below the Sony WH-1000XM6, so on aggregate review consensus this is a step backwards. The gains are concentrated in battery (8.1 to 9.0). You do give up ground on calls (9.6 to 7.0) and noise cancelling (9.6 to 7.5). On paper: battery life 40 h to 50 h, weight 254 g to 232 g and battery life (anc on) 30 h to 44 h. Worth checking: codecs goes SBC, AAC, LC3, LDAC to SBC and microphones goes 12 to 4. It is at least $248 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.
