Abstract
A head set apparatus capable of a wireless communication by a predetermined wireless communication system. The wireless communication system includes at least a first communication mode and a second communication mode. The first communication mode enables a data transfer with a partner apparatus and a second communication mode carries out a wireless communication with the partner apparatus with a period shorter than that of the communication in the first communication mode while the wireless connected state remains. The head set apparatus includes a communication section for carrying out a wireless communication by the predetermined wireless communication system and a control section for making the head set function as a head set when the communication state in the communication means is in the first communication mode and for making the head set function as a wireless key for security when the communication state is in the second communication mode.
