ABSTRACT:
A portable electronic device can detect whether an output unit of an accessory is connected to the body of a user and determines audio output units to which its application will transmit audio signal. The portable electronic device comprises an interface connected to the accessory, an application handling unit and a control unit. The control unit determines if the accessory is attached to the body of a user, selects audio output units to be used for the electronic device and transmits audio signals to the selected audio output unit for the application.
