If you are like me you need something like this. When I go walking with my ear buds on every time I turn my head one pulls out.
For a short time I used a big paper clip to clip it to my shirt but that was a pain to put on and take off. So I designed this device loosely based on a flat plastic paper clip I have seen before. It's easy to put on and remove, it fits the "Y" connection on all Apple ear buds perfectly and is low profile, you can barely tell you have it on. And best of all, no more ear buds getting ripped out of my ears when I turn my head.
