Product identity

The Avantalk TREBLAB C7 is a single-ear Bluetooth headset with a built-in microphone, designed for professionals who spend long hours on calls. It targets truck drivers, call-centre staff and home-office workers who need clear voice pickup without blocking ambient sound. The unidirectional microphone reduces background noise so speech stays intelligible in noisy environments.

Build integration

Bluetooth 5.4 pairs the headset with phones, laptops or desktop computers at distances up to 33 ft, and it can maintain simultaneous connections to multiple devices. No dongle or base station is required, freeing USB ports for other peripherals. The IPX4 rating protects against sweat and light rain, making the unit suitable for mobile use inside a vehicle or while moving between workspaces.

Upgrade context

The headset replaces older single-ear models that rely on earlier Bluetooth versions, shorter battery life or proprietary chargers. Moving to Bluetooth 5.4 improves link stability and reduces drop-outs during extended calls. The 45-hour talk time and 2.5-hour Type-C recharge eliminate daily charging routines. Buyers who need stereo audio for music or dual-ear noise isolation should look elsewhere.
