a wearing member worn on a head of a user;
a display device configured to display video;
a supporting member configured to support the display device;
a coupling member that is coupled to the wearing member and the supporting member and that is configured to move both of the display device and the supporting member from a first position to a second position different from the first position, wherein the first position is a position in which the user is able to visually recognize the video;
a sound output device disposed at an outer surface of the supporting member; and
a control device configured to control an output of sound output from the sound output device, wherein
the sound output device includes a first sound output device and a second sound output device,
the control device causes the sound to be output only from the first sound output device when the display device is located in the first position, and causes the sound to be output only from the second sound output device when the display device is located in the second position,
the first sound output device is closer to an expected head position determined by the wearing member than the second sound output device when the display device is located in the first position, and
the second sound output device is closer to the expected head position than the first sound output device when the display device is located in the second position.
