JBL Tune 770NC Black Bluetooth Headphones with Adaptive Noise Cancellation

Description

The JBL Tune 770NC wireless on-ear headphones in a black finish stand out as a major reference in the mid-range audio segment for telephony accessory resellers and multimedia specialists. Designed to reconcile active mobility and acoustic comfort, this model integrates an Adaptive Noise Cancelling (ANC) system. This technology continuously adjusts the level of sound isolation according to the sound environment, while offering Smart Ambient modes (Ambient Aware and TalkThru) to keep control over surrounding noises or take a call without removing the headphones.

On the electro-acoustic side, the JBL Tune 770NC uses two 40 mm dynamic drivers restoring the JBL Pure Bass Sound profile, renowned for the depth of its bass and the clarity of its mid-high spectrum. Its Bluetooth 5.3 controller supports LE Audio technology and multipoint connection, allowing seamless switching between two synchronised sources (for example, from a tablet to a smartphone when receiving a call). The device embeds a 690 mAh (3.7V) Lithium-ion Polymer battery providing up to 70 hours of continuous listening in standard mode and up to 44 hours with noise cancellation activated, rechargeable via its USB-C port.

The assembly of the Tune 770NC prioritises lightness and robustness with a high-density ABS polymer chassis with a total weight of 232 grams. Its on-ear shells articulate flat and fold inward toward the headband to facilitate transport and storage. For stock managers and the B2B maintenance workshop, the device integrates easily replaceable functional sub-assemblies, notably the ear cushions with a snap-on mechanical fixing and the detachable 3.5 mm mini-jack auxiliary audio cable allowing passive use without power.

Workshop & Usage Advice

To reduce the rate of after-sales returns related to connection defects or battery management, we recommend that you inform your clients about good charging practices. The use of unregulated high-power fast charging blocks can trigger the safety mechanism of the headphones BMS electronic circuit: prefer a standard 5V / 1A mains adapter. In the event of multipoint Bluetooth pairing desynchronisation, perform a factory reset by holding down the Volume + and Volume - buttons for more than 5 seconds until the indicator light of the right earphone turns solid. Finally, when replacing the ear cushions, use a non-aggressive nylon lever to detach the lugs without risking tearing the acoustic filter covering the speaker membrane.
