Hi.Do you already have a wireless microphone?If yes,does it have external speaker jack or any jacks for external equipment..If NO,search Amazon for Bluetooth Transmitter Microphone..
First off,what is the EXACT Make & Model of the microphone & headphones you want to transmit to?
It sounds like your microphone has a built in TRANSMITTER that sends the signal to a Bluetooth RECEIVER(USB dongle).
The Bluetooth headphones need to be paired to a stereo SO they must also contain a BT RECEIVER,with the stereo acting as the TRANSMITTER.
Let me look at information on the mic & headphones & I'll get back to you..
