Bluetooth Module

Is there such thing as a stand-alone, battery operated Bluetooth module that you can feed audio into, to be received by a standard Bluetooth headset?
Ive looked around Google, but I cant really find something. My GOPS systems audio is whisper quiet, so I would like to feed its audio to a bluetooth headset, wirelessly...since I have a few kicking around.

thanks

Yes, they were quite popular before the iPhone got A2DP.

Disnt think of loking under "Dongle"...thanks, I knew they must have existed somewhere

You better check the protocol compatbility before you buy. If your headset uses the headset profile and those dongles use the A2DP profile you won't be able to link them.
