Poly Y-Training Cable
The 3.5mm Y-training cable connects two Blackwire 5200 USB headsets to the USB port for monitoring and training purposes. Both users can hear the conversation, but only one headset (red end on the Y-cord) will have the microphone turned on. The microphone of the second headset (supervisor/trainer) will be muted.
Compatible with: Blackwire 5210, Blackwire 5220
This cable is for the Blackwire 5200 series only. No other Blackwire headset model that uses a 3.5mm jack is compatible with this cable.
