PURPOSE: An earphone for being separable is provided to prevent resource waste by providing a structure of freely controlling the length of a cable. CONSTITUTION: An earphone is divided into several blocks. The earphone can control a cable freely. The earphone provides a structure in which only a broken part can be selectively separated. The earphone uses a separable cable so that waste is prevented and the cable is efficiently managed. Earphone prevents an entire cable from being thrown away due to disconnection. Only a disconnected part is exchanged by forming sound portion and jack portion cables like a block having a fixed length. The earphone provides a structure of replacing only a part of the cable causing the disconnection. |
