A leading edge 23B of the arm 23A is in contact with a dent QP of a root part on the back side of the concha for holding, whereby the headphone device is held at two-points by the driver unit 21 and the leading edge 23B of the arm 23A. Thus, as the headphone device is attached at the two-points by the driver unit 21 and the leading edge 23B of the arm 23A with respect to the concha of various sizes and shapes, it is possible to provide excellent comfort and stability to all users when mounted without pain, irrespective of the shape and size of the concha. |
