The JBL Tune 770NC headphones combine Adaptive Noise Cancelling with JBL Pure Bass Sound for an immersive listening experience that lasts up to 70 hours with ANC off and 44 hours with it on. A quick 5-minute charge gives you an extra 3 hours of music, so you can keep going through busy days and long commutes. Lightweight and flat-folding, they connect to two Bluetooth devices at once so you can switch from watching a movie to taking a call without missing a beat. Use the JBL Headphones app to customize your sound and enable voice prompts in your language. VoiceAware lets you hear yourself during calls, and on-ear controls make it easy to manage music and your voice assistant. Includes JBL Tune 770NC headphones, USB‑C charging cable, detachable audio cable, quick start guide and safety information.
