Step 5: Attach Wires

Wrap the a red and black wire around the bluetooth headset and then glue it in place making certain to leave enough room to solder the ends of the wires to the bluetooth microphone terminals.

Attach a red wire to the terminal that the positive end of the microphone was attached to and a black wire to the terminal that the negative end was attached to.

Hi. I love this idea. I have a quick circuit addition that you should consider. You should add a 1 microfarad, 25 to 50 Volt non-polarized electrolytic capacitor (A mono ceramic would work too) inline with the positive side of the microphone wire. This will remove the voltage so that you are not sending voltage to your playback device and potentially damaging the headphone or line out of that playback device.
