Your Personal Sound Sanctuary — Anywhere You Go.

The JBL Tune 770NC is a premium over-ear headphone built for those who refuse to compromise on sound, comfort, or battery life. With Adaptive Noise Cancelling, JBL Pure Bass Sound, and up to 70 hours of playtime, it’s engineered for the long haul — whether that’s a cross-country flight or a full workday.

• Adaptive Noise Cancelling (ANC): Intelligently reads your environment and blocks out background noise — so your music stays front and center, no matter where you are.
• Ambient Aware & TalkThru: Stay in control of your surroundings. Ambient Aware lets outside sounds in when you need them; TalkThru lowers your music and amplifies voices for quick conversations — no headphones off required.
• JBL Pure Bass Sound: 40mm dynamic drivers deliver deep, powerful bass and crisp, balanced audio across every genre.
• Up to 70 Hours Battery Life: 70H with ANC off, 44H with ANC on. Running low? A 5-minute Speed Charge gives you 3 more hours of playback. Full charge in just 2 hours via USB-C.
• Bluetooth 5.3 with Multipoint: Connect to two devices simultaneously and switch between them effortlessly — phone call on your mobile, video on your laptop, no interruptions.
• JBL Headphones App: Fine-tune your EQ, customize controls, manage ANC modes, and update firmware — all from your phone.
• Foldable & Built for Travel: At 232g with a flat-fold design, soft PU leather ear cushions, and a padded adjustable headband, the 770NC is as comfortable as it is portable.
