SOLUTION: The type to be used by holding at the entrance of the earhole 6 is configured by inserting the fit cover 2 providing a U shaped projected portion 5 into a mounting recessed/projected portion 4 of the head phone main body 1 so as to obtain internally an effective acoustic feeling by thinly forming ring state barrier ribs 3a, 3b, 3c to the head phone main body 1. The type to be inserted into the earhole 6 is configured by inserting the fit cover 2 which is thinly formed ring state barrier ribs 3a, 3b, 3d into the mounting recessed/projected portion 4 of the head phone main body 1 without forming the above mentioned U-shaped projected portion 5.
