A wireless microphone () comprises a radio transmitter for transmitting radio signals carrying audio signals to a hearing device. The wireless microphone () further comprises at least one coupling element () for detachably fixing one of various interchangeable functional modules () to the wireless microphone (). The coupling element () is designed to fix the interchangeable functional module () to the wireless microphone () by mating with a coupling element () of the interchangeable functional module (). The coupling elements () comprise electrical contacts () for electrically connecting the interchangeable functional module () to the wireless microphone () when the interchangeable functional module () is fixed to the wireless microphone () by means of said coupling elements (). The coupling element () constitutes a bidirectional electrical interface between the wireless microphone () and the interchangeable functional module (). The wireless microphone () can be limited to an assistive listening device with basic functions and features, extendible by the user with extra functions and features as needed.

A mobile transceiver () comprises several receivers () for receiving electrical or electromagnetic signals carrying audio signals and a radio transmitter () for transmitting radio signals carrying audio signals. The mobile transceiver () comprises a prioritizing module () for assigning priority values to audio signals received by the receivers (). The prioritizing module () is designed to assign priority values in accordance with priority values assigned to the receivers () that received the audio signal concerned and/or to signal identifiers contained in the received electrical or electromagnetic signals carrying the audio signal concerned. The mobile transceiver () makes it possible to receive several audio signals separately from different audio sources, to prioritize automatically the received audio signals, and to select automatically and transmit one of the several received audio signals to the user, thereby assisting the possibly hearing impaired user in differentiating audio signals from different audio sources.
