A body-worn audio gateway device transmitting audio signals comprised in close-range electromagnetic signals may be used outside a car, where it may provide for hands-free mobile telephony and listening to music streamed directly to hearing devices worn by a user. When the user enters the car, he or she may want to use a corresponding in-car audio gateway device for the same purposes. This typically requires manual interaction e.g. to trigger the switch-over and to maintain hands-free operation of a carried mobile phone. Furthermore, the audio gateway devices may disturb each other, which may lead to malfunction, more troublesome interaction and/or reduced audio quality. To overcome this, the invention foresees means for detecting when the user enters and/or leaves the car and for automatically disabling functions of the first audio gateway device when the user is in the car.
