The listening experience – all day long. The JBL Live 770NC headphones deliver powerful JBL Signature Sound with a comfortable over-ear design. When you're deep in your flow, True Adaptive Noise Cancelling with Smart Ambient Technology protects you from distractions. And if you want to stay aware of the world around you, you can even have a conversation without taking off the headphones. Easily access your preferred voice assistant by saying an activation word or tapping on the earcup to play your favorite playlist, send a text to a friend, check the weather, and much more. You can enjoy 65 hours (50 hours with BT+ANC on) of music streaming. Need even more? A quick 5-minute charge gives you an additional four hours. The JBL Live 770NC can connect to two Bluetooth devices simultaneously, so you won't miss a call even while watching a movie on your tablet.
