According to an embodiment of the disclosure, disclosed is an electronic device that includes a first connector electrically connectable to an external electronic device, a second connector electrically connectable to an external audio plug, a wireless communication circuit, and at least one processor. When the electronic device is connected to the external electronic device through the first connector, the at least one processor may receive a first digital audio signal from the external electronic device through the first connector, convert the received first digital audio signal into a first analog audio signal, and output the converted first analog audio signal through the second connector. When the electronic device is connected to the external electronic device through the wireless communication circuit, the at least one processor may receive a second digital audio signal from the external electronic device through the wireless communication circuit, convert the received second digital audio signal into a second analog audio signal having a sound quality lower than that of the first analog audio signal, and output the converted second analog audio signal through the second connector.
