Wireless/Rechargeable Headset

I'm looking for a headset either bluetooth or RF that can be recharged through a usb port so I don't have to keep shoving batteries into it. I would also prefer the smaller usb adapter as opposed to the wired usb connection that goes to the wireless transmitter/receiver device, so I'm guessing only the BT are that small. So basically this device would, at idle recharge, take up two USB slots, and if the recharge station was wired that would be fine. Anyone know of anything like this? If not I guess I'll mail this idea to myself then pitch it to Plantronics and CL This kind of setup is ideal for PC gamers using voice software. I have a USB headset right now, but the wire is a pain.
Thanks in advance.
