JBL Live 770NC headphones deliver powerful JBL Signature Sound in a comfortable over-ear headband style. When you're deep in your flow, True Adaptive Noise Cancelling with Smart Ambient technology keeps you free from distractions. Or, if you want to keep an ear open to the world around you, you can even have a conversation without taking the headphones off. Easily access your preferred voice assistant with either a hotword or a tap on the earcup to play your favorite playlist, text your friend, check the weather, and much more. You’ll enjoy 65 hours (50 hours with BT+ANC on) of music streaming. Need even more? A 5-minute speed charge gets you another four hours. The JBL Live 770NC 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.
