Where do I find a hinge clip for beats solo 3?
The be precise, I am looking for the clip that goes inside the hinge, that snaps the ear muff into place when you close the headphones. I can only find 2 hinges and clips as a package, and $20 or more Canadian dollars is a little much for a 5 cent part.
