Imagine moving the mouse while talking on the Skype, it actually happen with this USB handsfree Skype mouse. I am just wondering if the volume over the other side will get louder when you move the mouse nearer to you and softer when away from you.

This 800 DPI optical USB mouse comes with a built-in USB sound card and earphone connector. The handsfree speakerphone function let you communicate in full-duplex mode. It supports Skype, VoipButser, VoipStunt, VoIPCheap, VoipDiscount, SparVoip, Internetcalls, poivY, WebCallDirect, VoipCheapCom, FreeCall and NetAppel. It is priced at $25.
