The present invention relates to an ear plug of an accessory for a mobile terminal and an accessory provided with the ear plug. An ear plug, provided on an accessory of a mobile terminal and inserted into a voice output terminal of the mobile terminal, for transmitting an electrical signal from the mobile terminal to the accessory, is divided into a ground part and first and second signal parts, wherein the second signal part disposed at the end of the ear plug comprises: a connecting part connected to the voice output terminal for transmitting an electrical signal; and an insulating part for blocking a connection with the voice output terminal so that the mobile terminal cannot recognize the coupling of the ear plug.
