Experience deep and powerful JBL Pure Bass sound and focus on your music while active noise cancellation filters out background noise. Bluetooth multipoint connection pairs your Tune 760NC headphones to two Bluetooth devices at the same time. Playback time is up to 35 hours with ANC on (and up to 50 hours when active noise cancellation is not used) and charging from empty to full takes about two hours. You can also use your headphones wired and thus continue listening to music indefinitely. The built-in microphone enables easy hands-free calls and the use of a voice assistant. Thanks to Google Fast Pair, the Tune 760NC headphones establish an instant connection with your Android devices. The headphones fold up compactly when you're not using them.
