Abstract
A communication circuit communicates with a right earphone worn on a right ear of a user and a left earphone worn on a left ear of the user to receive a first output signal generated by a first motion sensor provided in the right earphone and a second output signal generated by a second motion sensor provided in the left earphone. A detector detects whether a third party has approached the user based on a difference value between the first output signal and the second output signal received by the communication circuit. A notification unit notifies the user that the third party has approached the user when the detector detects that the third party has approached the user.
