DIY Bluetooth Adapter for any Headset

I recently bought a new headset that I'm mostly satisfied with. Except I would really like the convenience of streaming music wirelessly!

Instead of buying a more expensive headset, I cut the cord, and went to work to create a bluetooth headset adapter. 

That's what I'm showing you today.

At first I looked at all the parts needed to make an adapter from scratch. But realized I could get most of the circuitry needed in a much smaller package, by modifying a cheap pair of bluetooth earbuds.

These are the only points we care about to transmit music wirelessly. And they need to be wired from the bluetooth chip to the audio jack.
