1. A first earpiece device, comprising:
a communication circuit;
a processor configured to be operatively connected to the communication circuit; and
memory storing instructions that, when executed by the processor, cause the first earpiece device to: generate a first communication link with a second earpiece device via the communication circuit;
store first audio data obtained from an external electronic device via the communication circuit in a buffer;
change a master role from the first earpiece device to the second earpiece device based at least on identifying a buffer level corresponding to the first audio data to be output via the first earpiece device, identifying a remaining battery capacity of the first earpiece device being smaller than a remaining battery capacity of the second earpiece device, a difference between the remaining battery capacity of the first earpiece device and the remaining battery capacity of the second earpiece device being greater than or equal to a threshold value, and identifying that a cover of a charging case device into which the first earpiece device and the second earpiece device are inserted is open when the remaining battery capacity of the first earpiece device is smaller than the remaining battery capacity of the second earpiece device.
