Step 1: What you're going to need...
What you're going to need:
Your broken headphones.
thin metal rods, I used cut up pieces of the metal from a binder clip, you could use finishing nails or whatever you can find.
a drill bit the approximate diameter of your metal rods
JB kwik weld
Step 2: Drill
Pay extra attention to kind of drill the ear piece on a slight angle so you don't pop out of the side.
When you're done, test fit your metal pins in the holes, if they are too small, go back in and wiggle the drill bit around a little. If they are too large, not to worry, you're going to fill them with epoxy anyway.
