Remember those zip up ear buds we saw at CES? Well, if you can’t wait for those to hit retail shelves here is a do it yourself version. Just simply purchase a stand alone zipper, then sew the wires into the fabric. Simple. You could sew the completed project into a sweatshirt, but I suggest investing in some velcro or something that would allow you to move the zip up ear buds from piece of clothing to piece of clothing.
