An acoustic device that includes a housing, a nozzle portion, a speaker hole, a first microphone hole, a speaker, a first microphone, and a processor configured to output a first signal through the speaker, receive a second signal corresponding to the first signal through the first microphone, output a third signal through the speaker when a magnitude of a first frequency band component of the second signal is greater than a first value, receive a fourth signal corresponding to the third signal through the first microphone, and determine that the protruding end surface of the nozzle portion is blocked and the acoustic device is not worn in a user's ear when a magnitude of a second frequency band component of the fourth signal is greater than a second value.
