## Long description

Yealink WH66 DECT Wireless Headset MONO TEAMS is a professional mono supraaural headset for office and contact-centre environments. It provides DECT wireless connectivity with Bluetooth support and a head-band wearing style. The headset is tuned for voice communication and conferencing with a frequency response covering 20–20000 Hz and a compact on-desk base that consolidates calls and device connections.
Advantages
The WH66 combines DECT range and Bluetooth flexibility to allow hands-free voice communication and simple integration with Unified Communications platforms and Yealink IP phones. A dedicated base with a capacitive touch screen centralises call control and device management, and the headset’s supraaural earpiece and head-band design deliver a stable fit while keeping one ear available to hear the surroundings. Built-in noise control technology and integrated microphones focus on voice clarity for clearer conversations.
Suitable for
Office professionals who need a wireless mono headset for voice calls and conferencing
Contact-centre agents requiring a comfortable head-band solution with DECT mobility
Home-office users who want a single workstation to manage desk phone, PC and mobile connections
Teams using certified UC platforms where native integration with Yealink phones is required
When it may not be suitable
This mono supraaural headset is intended for single-ear listening and voice-focused tasks; it may not suit users who need stereo audio for media playback or immersive listening. Environments requiring waterproof or ruggedised headsets, or those needing full hearing isolation, should consider alternative models designed specifically for those conditions.
