Single-Ear Headset for Work Calls

The Alphacool TREBLAB C7 is a single-ear Bluetooth headset built for clear voice communication. A unidirectional microphone reduces background noise so the other party hears you, not the environment. It connects wirelessly to phones, laptops or computers and weighs 84.6 g with memory-foam cushions and an adjustable headband for all-day wear.

Bluetooth 5.4 and 45-Hour Battery

Bluetooth 5.4 provides a stable link up to 33 ft and supports multi-device pairing. The battery delivers up to 45 hours of playtime and recharges in 2.5 hours via USB Type-C, so the headset is ready for long shifts without frequent charging breaks.

Suited to Mobile Professionals, Not Stereo Listeners

This headset fits truckers, call-centre agents and remote workers who need one ear free for situational awareness. Buyers who want stereo sound for music, immersive gaming audio or active noise cancellation for loud environments should look at dual-ear models instead.
