The COMfortel® D-Stick EZC-5200BS adds Bluetooth connectivity to your existing COMfortel® D-400. The expansion via Bluetooth 4.2 allows you to conveniently connect commercially available Bluetooth headsets to the COMfortel® D-400. The use of a wireless headset offers you the familiar advantages of increased freedom of movement at the workplace. Our tip: for spatially concentrated use of wireless headsets (e.g. call / contact center), we recommend using DECT-based (COMfortel® H-500) instead of Bluetooth-based headsets.
