- Outstanding battery longevity delivering up to 76 hours with ANC disabled and up to 50 hours with ANC enabled
- Rapid 5-minute speed charging providing up to 5 hours of playback from empty
- Latest Bluetooth 6.0 platform with multi-device multipoint switching and dual platform fast pairing
- Wired USB-C to 3.5 mm analog bypass supporting Hi-Res Audio playback from 10 Hz to 40 kHz
- USB charging cable omitted from retail packaging, requiring user-supplied charging gear
- Wireless audio frequency response restricted to 20 kHz compared to 40 kHz over wired connection
Overview
Engineered for sustained listening endurance and daily commuter mobility, JBL’s Tune 780NC centers around an ultra-efficient power envelope that delivers up to 76 hours of continuous wireless playback with active noise cancellation disengaged, or up to 50 hours with cancellation active. The physical assembly weighs just 0.494 lbs (225.2 g) and utilizes multi-axis folding hinges that collapse the earcups into a compact footprint for travel. Its over-ear cushions provide a 2.36 x 1.67 in (60.0 x 42.5 mm) inner chamber with 0.83 in (21.0 mm) of pad depth, distributing clamping pressure evenly across the perimeter of the ear to prevent localized fatigue during extended work sessions.
Acoustic delivery is handled by 40 mm (1.57 in) dynamic drivers tuned for balanced frequency response and wide dynamic range, reaching 98 dB SPL sensitivity at 1 kHz with a maximum sound pressure level of 93 dB. Wireless streaming operates over a modern Bluetooth 6.0 connection across the standard 10 Hz to 20 kHz spectrum, supported by seamless multipoint switching, Google Fast Pair, and Microsoft Swift Pair for low-friction transitions between laptops and mobile handsets. For critical desktop listening, an included 47.2 in (120 cm) USB-C to 3.5 mm analog cable bypasses the internal wireless DSP entirely, extending high-frequency response up to 40 kHz for uncompressed high-resolution audio.
Active ambient isolation combines adaptive noise cancelling with dual beamforming microphones rated at -38 dBV/Pa sensitivity, actively suppressing steady-state background rumble while keeping voice transmissions clear on conference calls. Smart Ambient modes—including Ambient Aware and TalkThru—allow wearers to maintain situational awareness without removing the headset. The internal 690 mAh lithium-ion battery manages thermal dissipation passively up to a verified operating ceiling of 113°F (45°C), while an integrated quick-charge circuit restores 5 hours of listening time from a 5-minute charge over standard 5V/1A USB power, mitigating the minor inconvenience of an omitted in-box charging cable.
