1. A terminal for controlling a wireless sound device, the terminal comprising:
a communication interface configured to wirelessly connect to at least one or more wireless sound devices; and
a processor configured to:
transmit and receive a positioning signal to and from the at least one or more wireless sound devices through the communication interface,
determine a relative position of the at least one or more wireless sound devices based on the positioning signal,
receive an acceleration sensor value from the at least one or more wireless sound devices through the communication interface,
determine a posture of the at least one or more wireless sound devices based on the acceleration sensor value,
determine a wearing state of the at least one or more wireless sound devices based on the relative position and the posture of the at least one or more wireless sound devices, and
transmit an audio signal to a worn wireless sound device among the at least one or more wireless sound devices through the communication interface,
wherein the relative position includes a distance to the at least one or more wireless sound devices and a direction of the at least one or more wireless sound devices with respect to the terminal,
wherein the communication interface includes at least two or more communication transceivers, and
wherein the processor is further configured to:
measure an angle of arrival (AoA) of the positioning signal using the at least two or more communication transceivers,
measure a time of flight (ToF) of the positioning signal, and
determine the relative position of the at least one or more wireless sound devices based on the AoA and the ToF.
