When headphone housings are tilted such that their upper portions are separated from side faces of the user's head and their lower portions are near the side faces, an arm of the display section is horizontal. Generally, the human head at ear portions is formed in a shape that is large at the upper portion and small at the lower portion. Accordingly, when the headphone housings are installed at the ear portions, the headphone housings are installed according to the shape and the arm is horizontal. This means that the arm is horizontal in a natural installation state. Adjustment of the display section is not complex and the display section has a well-balanced appearance.
