Detailed Specifications

Yealink WHM621UC DECT Wireless Mono UC Headset

Overview :

The Yealink WHM621UC is a DECT-based wireless mono headset designed as a replacement headset unit for Yealink WH62/WH66 wireless communication systems. It is used in enterprise and contact center environments where stable long-range voice communication and UC platform integration are required.

It operates using DECT wireless technology paired with compatible Yealink DECT base stations, providing significantly longer range than Bluetooth headsets and stable voice transmission in high-density office environments.

The headset is built for professional voice workflows, supporting features such as noise-canceling microphones, wideband audio, busylight indicator, and call control functions like answer, mute, and reject.

This unit is not a standalone headset and requires a compatible Yealink DECT system (WH62 or WH66 base) to operate. It is intended for structured UC deployments in offices, retail environments, and customer service operations where roaming and multi-hour talk usage are required.

Key Features :

  • DECT wireless technology for extended communication range
  • Designed as replacement headset for WH62/WH66 systems
  • Wideband audio improves clarity in UC calls
  • Noise-canceling microphone reduces background interference
  • Busylight indicator supports enterprise call awareness
