PROBLEM TO BE SOLVED: To provide a combined earphone/microphone and an ear cover for using an earphone and the ear cover independently of each other or in combination as necessary and also using them together with a microphone. SOLUTION: An earphone 130, a microphone and an ear cover 120 can be used at a time and also used independently of each other. A fixed cover, the earphone 130 and the cover 120 are defined as three primary components and have the mutual connecting mechanisms respectively. In a using state, a fixed base 110 is connected to the earphone 130 and only the function of the earphone 130 can be used. Meanwhile, the base 110 is connected to the cover 120 and only the function of the cover 120 can be used. Furthermore, the fixed cover, the earphone 130 and the cover 120 are connected together and the functions of the earphone 130 and the cover 120 can be uses at a time. Then the microphone can be added to the earphone 130 as necessary.
