Timothy Dubitsky created hood.e, a jacket with integrated headphones that broadcasts music into your ears from any mp3 player you plug into it. With an aim towards safety when walking through urban environments, Dubitsky integrated the headphones directly into the fabric of the hoodie so it plays music in your ears without blocking everything else out.
I've seen a lot of jackets with integrated headphones. Unfortunately, most of them simply allow for you to weave your own headphones into your garment to hide the wires and to keep it in place. Kudos to Dubitsky for designing a solution that is functional, solves a problem of safety, and that integrates the technology directly into the garment. My only question: will it handle the wash?
