PROBLEM TO BE SOLVED: To achieve an operation on music to be performed without using an operational part, and without adding a new component. SOLUTION: A microphone 35L(R) for collecting noise that picks up ambient sound to convert it into a sound signal and that is configured with a headphone integrally, and a noise detector 37L(R) that generates a cancel signal for alleviating the noise when noise is detected from the sound signal, are provided. A signal processor 32L(R) that adds the cancel signal generated by the noise detector 37L(R) to an audio signal to output the audio signal, and a driver to which the audio signal output from the signal processor 32L(R) is supplied and which outputs the audio signal as sound, are provided as well. The operation content of a user to the headphone 2L(R) is determined by analyzing the sound signal, and a command for controlling an operation related to reproduction of the audio signal is generated depending on the determination results.
