Abstract: An electronic device and method for identifying the type of earphone and controlling audio output based on the identified type of the earphone. The electronic device includes an interface configured to detect an input of an earphone having a first audio output module with a first impedance value and a second audio output module with a second impedance value, and a processor configured to control the interface to detect the input of the earphone, check the first impedance value of the first audio output module and the second impedance value of the second output module, determine a type of the earphone based on at least the first and second impedance values, and adjust a characteristic related to the audio output of the electronic device based on the determined type of the earphone.
