Along with powerful JBL Signature Sound, the 40mm drivers offer immersive JBL Spatial Sound that turns any stereo content from any device into virtual surround sound.

Wirelessly stream high-quality sound even at lower bit rates with the help of the latest Bluetooth technology. Audio Mode gets you the best available sound, while Video Mode makes sure the sound and visuals of your movies and games are always in sync.

With four noise-sensing mics, True Adaptive Noise Cancelling means zero distractions, whether it's time to focus on your studies—or get your groove on. And if you want to hear the world around you without removing your headphones, Smart Ambient sharpens the sounds of your surroundings

The JBL Live 770NC Wireless Over-Ear Headphones (Model: JBLLIVE770NCBLK) in sleek matte black deliver powerful JBL Signature Sound packed into a comfortable, modern design. Equipped with custom-tuned 40mm dynamic drivers, these headphones deliver pounding bass, crisp mid-tones, and soaring highs. Beyond traditional stereo sound, they feature advanced JBL Spatial Audio processing, which converts standard audio from any paired device into an immersive, virtual surround sound experience—making you feel like you are standing right in the center of a live concert or movie scene.

The core highlight of the Live 770NC is its intelligent True Adaptive Noise Cancelling system. Utilizing four advanced noise-sensing microphones, the headphones continuously monitor your environment in real time to cancel out distracting ambient noises like airplane engines, city traffic, or loud office chatter. When you need to stay aware of your surroundings, the Smart Ambient and TalkThru technologies sharpen external sounds. This lets you safely cross busy streets or have a quick conversation with a colleague without ever removing your headset.

Operating on the latest Bluetooth 5.3 standard, it supports efficient audio streaming and seamless Multi-Point Connection, letting you switch instantly from a video on your tablet to an incoming voice call on your smartphone. Boasting an extraordinary battery runtime of up to 65 hours with ANC turned off (and 50 hours with it engaged), it keeps your music flowing for days on a single charge. Combined with a premium fabric-mesh headband, plush memory-foam ear cushions, dual beamforming call microphones, and full integration with the JBL Headphones app, it offers an elite personal listening experience for daily commutes and workspace productivity.
