ABSTRACT:
In an arrangement in which the earphone cord 16 of earphones 15 is connected to a remote control unit 11 and the remote control cord 12 of this remote control unit 11 is detachably connected to a portable audio unit 10 by means of a plug 14, a battery 19 that drives the elements inside the remote control unit 11 is embodied in a plug unit 13 having the plug 14. Specifically, a battery accommodation recess 23 is formed in the plug unit 13, and a battery holder 26 into which the battery 19 is fitted is detachably attached to this battery accommodation recess 23. As a result, with the plug 14 inserted into the portable audio unit 10, the portable audio unit 10 and the plug unit 13 are an integral unit and do not have the weight of the remote control unit 11 if the portable audio unit 10 is kept in a pocket or handbag. The remote control unit 11 becomes lighter and smaller to the extent of the battery 19.
