WIILGN 101U Single Ear USB Headset Black 2M Cord

Single-Ear USB Headset for Call Centres

The WIILGN 101U is a wired mono headset built for high-volume voice work in contact centres and home offices. Its single-sided design keeps one ear open to the surrounding room while the 30 mm driver covers a 20Hz–20KHz response range. A USB connection supplies both power and audio without extra drivers. Weighing 180 g, it targets professionals who spend full shifts on calls.

Passive Cooling and Low Power Draw

With no battery or wireless module the unit draws minimal current from the USB port and generates no noticeable heat during extended sessions. The 32 ohm impedance and 115 dB sensitivity deliver loud, clean output at low voltage. Active noise cancellation on the microphone suppresses background sound without adding fan noise or thermal load. THD stays below 0.1 and signal-to-noise ratio reaches 80 dB.

Inline Controls and Adjustable Boom

A 2 m cable includes a 0.5 m drop to an inline controller offering volume up and down plus separate mute buttons for microphone and speaker with LED status indicators. The metal microphone boom rotates 330 degrees for precise positioning. Oval memory-foam ear cushions wrapped in protein leather and a padded adjustable headband aim to reduce fatigue during all-day wear. Acoustic shock protection guards against sudden volume spikes.
