Earlier this year, Plantronics introduced the CS50-USB, a wireless headset specifically intended to work with software-based VoIP phones such as Skype.

The CS50-USB combines several pieces of technology into its overall solution, including a base station that plugs into a USB port on the host computer, a small over-the-ear headset that communicates with the base station via 900Mhz radio, and a software component that integrates the hardware with the user's preexisting software-based phone..
