1. A sound output control device, comprising:
an orientation detecting unit configured to detect a state of orientation of a face of a user with a sensor included in headphones worn by the user;
an ambient sound obtaining unit configured to obtain ambient sound around the user from a microphone included in the headphones;
an ambient sound reducing processing unit configured to perform, based on the ambient sound obtained by the ambient sound obtaining unit, processing of reducing the ambient sound for sound output of the headphones;
a determining unit configured to determine whether the user is using a means of transportation; and
when the determining unit determines that the user is using the means of transportation, a sound output control unit configured to, when the state of the orientation of the face of the user detected by the orientation detecting unit is in a first state, cause sound to be output with the ambient sound reduced by the ambient sound reducing processing unit, and when the state of the orientation of the face of the user detected by the orientation detecting unit is in a second state changed from the first state, make audibility of the ambient sound higher than in a state where the ambient sound has been reduced by the ambient sound reducing processing unit.
