The ConneXt P 2-Way PC/Phone Headset Adapter from VXi is designed to easily switch between PC (softphone, Skype) and desk phone calls, when using a headset. The computer connection uses a USB and the desk phone connection uses a RJ-9 phone cord. This headset adapter also features microphone volume adjustments (up to +15 dB available) to boost transmit volume, when needed. It reduces desktop clutter with a headset hanger.
