The JBL Live 660NC are a bit better for most people than the JBL Tune 770NC. The Live 660NC are slightly better built and have more space to comfortably accommodate different ear sizes easier than the Tune 770NC, which have small ear cups. The ANC on the Live 660NC blocks more external noise, too. However, the Tune 770NC boast a much longer battery life and a better sounding mic system in noisy areas.
