I love this simple solution! No matter how carefully I try to store my iPod headphones, they're usually a tangled mess by the time I take them out of my bag — so I'm a huge supporter of cord management.
Sometimes even the most high-tech gadgets can be improved with the simplest of projects. Case in point: these earbud clips ($10 for a package of four) by PKOH. The colorful plastic clips slide secure your earbuds after wrapping them around your iPod.
