Headphones deliver a powerful JBL signature sound in a comfortable on-ear headband style. When you're deep in your flow, true adaptive noise cancelling with smart ambient technology keeps you free from distractions. Then, when you want to keep an ear open to the world around you, you can stay aware as you continue listening to your favorite playlist—or even have a conversation without taking the headphones off. Easily access your preferred voice assistant with a tap on the ear cup to cue up a song, text your friend, check the weather, and much more. You’ll enjoy 65 hours (50 hours with BT+ANC on) of music streaming. And if you still need more, a 5-minute speed charge gets you another four hours. The Live 670 can connect with two Bluetooth devices simultaneously, so you’ll never have to miss a call, even if you’re watching a movie on your tablet.
