The present invention relates to a roll for winding the wire of a detachable earphone which can wind even extra long wires if necessary and which is detachable when not needed to facilitates use and portability. The winding roll can, of course, conveniently wind up the wire if it is too long and can be unwound if the wire is too short, and when the full length of the earphone wire is needed or when there is no need to wind the wire, the winding roll can be completely separated from the earphone wire so that there is no need to carry the extra, bulky and heavy winding roll. In addition, the winding roll is built in such a way that the wire can be wound smoothly without getting entangled, and the winding speed can be doubled to provide a speedy winding operation. |
