JBL Live 660NC
JBL Live 670NC Wireless
The JBL Live 660NC Wireless and the JBL Live 670NC Wireless have different designs. The former is an over-ear design, while the latter has an on-ear design that sits directly on your ear. That said, their distinctions go beyond simple design differences. While both headphones have a boosted bass response, the Live 670NC have an overwhelming amount of bass that can muddy the rest of the mix. By contrast, the Live 660NC follow our target curve more closely, with a balanced sound that leans towards being bass-heavy. The Live 660NC have a better performing ANC system and better mic recording quality, making them a better fit for calls, but they lack the Live 670NC's monumental 88-hour battery life.
