When you want to listen to music on the go, the easiest output device is usually a set of earbuds. They are very small, and generally provide a pretty decent sound (depending on which ones you choose). The biggest complaint I have about them is that no matter how tightly you wrap them up, they are always a tangled mess when you remove them from your pocket. So how does one keep the cord nice and neat? One of the easiest ways I’ve seen involves nothing more than a contact lens case.
While you might not think that an ordinary contact lens case is good for much, one Instructables user figured out that it is perfect for wrapping up your earbuds. All you need to do is cut out two small holes for the ear pieces to slip into, then wrap the cord around the center. Insert the whole thing in your pocket, and you’re good to go!
