The WHB640UC is the DECT base station made for Yealink’s WH64 hybrid wireless headsets (both Mono and Dual versions). It’s the docking / connectivity hub that enables the headset to connect to PCs, IP phones, and third-party phones, plus provides power charging, status lights, etc. It can be bought as a replacement/standalone part.
Key Features & Capabilities
Here are the main features of the WHB640UC and the WH64 + base combo, to give context:
- Wireless Connectivity: The headset uses DECT (for reliable wireless from the base) plus Bluetooth for connecting to other devices. The base manages the DECT side.
- Ports and Connections on the Base:
- Micro USB 2.0 port (often used for connecting IP phones via USB)
- USB-C 2.0 port (for PC connection)
- Mini USB port (usually for third-party phone integration using EHS / telephone cable)
- DC power input port
- Busylight port (for an external busy light accessory)
- Compatibility: Works with both the WH64 Mono and Dual models of the headset. If the headset is UC-certified (or Teams version), the base works with that too.
- Performance: The DECT part gives good wireless range; battery talk times are high (when paired with the headset) etc. But note: the base station doesn’t itself define talk time—that’s headset + mode.
