Abstract
An audio output device is provided. The audio output device includes a housing, an audio output unit outputting audio data, a first contact sensor configured to detect a contact of an external object, a second contact sensor configured to detect a contact of the external object, a proximity sensor configured to detect a proximity of the external object within a predetermined distance, and a processor operatively connected to the audio output unit, the first contact sensor, the second contact sensor, and the proximity sensor. The processor may be configured to execute a wearing detection mode of the audio output device, to determine the contact of the external object through the first contact sensor, to determine the contact of the external object through the second contact sensor, to determine the proximity of the external object through the proximity sensor, and to determine that the audio output device is in a state worn by the external object.
