iPod MP3 Player Carrying Case

My other half has this set of electronic gadgets that he carries around, to provide music during his workday. It's just a little mp3 player with a requisite charging cord, but since he's not an earphone type of guy, he also has this speaker with its own cord. The speaker originally came with a snug fitting drawstring bag, but it doesn't hold much else. Lately he's been carrying everything in a ziplock, which doesn't provide protection nor is it an elegant solution, all in all. So I told him that I would make him something and kill two birds with one stone: he would end up with a functional carrying case and I would have material for a new tutorial.
