Intro: IPhone Earphone Hack/Fix
I have made an instructable on my iphone earphone hack/fix. It actually happened when I had an issue when they kept falling out. So I used a metal band from an old set of wiper blades from the trash can at the auto parts store.
If you don't want to tear apart a good set from your own car then do what I did. I waited till a rainy day when we had a really hard rain. That'll usually brings in people with bad wiper blades. Just dig through the trash for a smaller car blade. Then proceed to tear it apart.
You are after the thin flat wire that holds the rubber blade in place.
Measure, and bend it in a u-shape and JB weld it in place, and your done. Just bend to get a tight fit so they don't fall out of your ears.
