I actually made this about five years ago but thought I'd share. I liked carrying my MP3 around, but sometimes the earphones' cord was a bit excessive, catching on things as I walked by, or I'd accidentally step on it when crouching to pick up something. At the time they were my only earphones as well, so I used them constantly and didn't like continually winding and unwinding it from a rubber band when I needed it, so it would just end up a tangled mess.
I had a bubblegum container that had been laying around prior to my dilemma, which I had kept hold of, thinking it may come in use one day. Well yes, that day was upon me.
I had only seen one other person on the internet use the exact same container for the exact same purpose (for the life of me I can't remember the site). The only exception being that it was strictly for carrying said earphones. If you wanted to use them, you had to take them out entirely, which still left the issue of duking it out with the long cord, and the container is left as wasted space in your pocket or bag.
I wanted mine to stay together, so that my earphones could be used and somewhat contained at the same time.
