We’ve featured quite a few DIY headphone wrappers, but this trick actually attaches it to your case, ensuring that you won’t lose your headphones. All you need to do is sew a few buttons on the case and then wrap your headphones around them – it couldn’t be simpler (or cheaper). The original mod was done on one of those iPod socks, but you could pull this off with any fabric or leather case you have – if you feel like drilling some small holes, you could probably even do something similar with a hard case.
