Earphone‘s wirding thread
Earphone‘s wirding thread

A small plastic tube with an earphone socket in one side is adding to the earphone cable. Wrap the earphone wire around the tube and then insert the earphone jack into the socket when no using the earphone. Not only the earphone is more convenient to carry, but also it solves the knotting problem of the earphone.
