An example wireless audio electronic device includes a first antenna, a communication circuit, and a processor. The processor may be configured to receive a positioning signal from an external electronic device through the first antenna so as to obtain first positioning information; obtain, from a different audio device located in a case together with the wireless audio electronic device, second positioning information for the positioning signal received by the different wireless audio electronic device; determine an angle of arrival of the positioning signal based on the first positioning information, the second positioning information, and the distance between the wireless audio electronic device and the different wireless audio electronic device; and transmit a response signal including information of the angle of arrival to the external electronic device.
