## Long description

The Yealink WH66 DECT Wireless Headset MONO TEAMS is a personal audio conferencing system designed for office and call center use. The WH66 base combines a 4.0 inch (480 x 800) capacitive touch screen with DECT wireless and Bluetooth connectivity, allowing integration with Yealink IP phones and major UC platforms. The base acts as a compact UC workstation: it manages phone calls, connects multiple devices (desk phone, mobile phone, computer), provides a 2‑port USB 3.0 hub, supports wireless charging for a mobile phone and can function as a speakerphone while the headset offers clear voice transmission for hands‑free conversations.
Advantages
The WH66 simplifies desktop collaboration by centralizing device connections and call control on a single plug‑and‑play base. The capacitive touchscreen enables intuitive one‑touch control of calls and settings. Built‑in Bluetooth and USB ports expand connectivity, while the headset and base support hands‑free operation. Yealink Acoustic Shield Technology and two integrated microphones reduce background noise to ensure clear voice transmission. An integrated busy light helps prevent interruptions during calls.
Suitable for
Office professionals using Yealink IP phones and UC platforms
Call centers and customer service agents requiring hands‑free DECT communication
Remote workers who need a tidy desktop UC workstation with screen controls
Teams that require wireless charging and a speakerphone option for small group calls
