Headphones include: a speaker configured to output sound based on an input signal; a microphone configured to receive touch sound produced when a touch is performed on a user; and a command output device configured to, on the basis of a sound signal derived from the touch sound received by the microphone, determine a touch operation corresponding to the touch performed on the user, to output a command corresponding to the touch operation.

Headphones

Headphones include a first microphone configured to receive ambient sound at an outside of an external auditory canal of a user; a second microphone configured to receive sound inside the external auditory canal; a speaker configured to output sound toward the external auditory canal; a determiner configured to determine whether or not wind noise has occurred by comparing a first signal based on the sound received the first microphone with a second signal based on the sound received by the second microphone; and a processor configured to output, to the speaker, a signal obtained by adding an input signal to the first signal when the determiner determines that wind noise has not occurred.

A sound output device includes: a first microphone configured to receive ambient sounds from around a user; a loudspeaker configured to output sounds toward an eardrum of the user; signal processing circuitry configured, in a case in which it is detected that an external terminal is in a playback state in which the external terminal provides a playback sound signal indicative of a playback sound, to generate a first reverse-phase signal based on a first signal derived from a sound received by the first microphone, and configured to impart predetermined frequency characteristics to the first signal in a case in which it is detected that the external terminal is in a stopped state that is not the playback state; and an adder configured to add together the playback sound signal and a signal output from the signal processing circuitry, to output a resultant signal for output by the loudspeaker.
