My bluetooth headband stopped making sound in one ear, for the second time, so I replaced the second speaker wire.

Soldering so close to the batter terminals makes me nervous, but I did anyways.

The original wire break.

Putting the control module back together. The other end of the wire still needs to be finished.

The wires get soldered to the pads where the old wires were, the wires get a spot of hot glue to stay in place.

The original fabric tape on the back of the speaker didn’t survive pealing it off, so I put a piece of hockey tape over the area to protect everything.

All the guts batch together again.

It all works again.

I am well aware that the effort to do the repair is more than the original purchase price. But, I do not need to wait the weeks for delivery, and I get practice.
