Abstract
A retractable device is provided for an earphone/microphone used with a cell phone. The device is formed of a housing with one rewinding spool for the earphone end of the cord with allowance for twisting of the connector end of the cord. The device with two spools allows for independent rewinding of earphone end portion of the cord and the connector end portion of the cord on different spools and the confinement of a middle portion of the cord in reversible winding cavity with the ends of the middle portion of the cord fixed so that middle portion can wind and rewind in the reversible winding cavity without leaving the cavity.
