JBL Live 770NC Headset Wireless Head-band Calls/Music Bluetooth Blue

The JBL Live 770NC is a wireless over-ear headset designed for calls and music, delivering JBL Signature Sound with comfortable circumaural earcups and a lightweight head-band construction. It supports Bluetooth connectivity, a frequency response of 20–20,000 Hz, and long battery life — up to 65 hours of playback (50 hours with Bluetooth and Active Noise Cancelling on). Dual-device Bluetooth pairing lets you stay connected to two devices at once, and a 5-minute quick charge provides about four hours of additional playback.

Advantages

True Adaptive Noise Cancelling with Smart Ambient technology reduces external distractions while allowing ambient sound passthrough when needed; hands-free voice assistant access and on-ear controls enable convenient call and media management; lightweight design (256 g) and soft earcups provide extended comfort for all-day use.

How to use

Charge the headset before first use, then pair it with your Bluetooth device following the standard Bluetooth pairing procedure. Use the on-ear controls to play or pause audio, adjust volume, switch ANC/Smart Ambient modes, answer or end calls, and activate your voice assistant by hotword or a tap on the earcup. Wear the headset with the headband over the top of your head and adjust the earcups for a comfortable seal to optimise sound and noise cancellation.

Recommendations

For best performance, update the headset firmware via the official JBL app when available, keep earcup cushions clean, and recharge the battery before extended trips. Use ANC in noisy environments and Smart Ambient when you need situational awareness.
