1. A wireless communications device for receiving a wireless speech signal and providing at least one output signal, the device comprising:

  • a) a control unit for controlling the operation of the wireless communications device;

    b) a selection means connected to the control unit and configured to allow selection from at least three output coupling modes, the at least three output coupling modes comprising a microphone mode, a telecoil mode, and a microphone/telecoil mode, each of the at least three output coupling modes for generating one of the at least one output signal of the device;

    c) a communication subsystem connected to the control unit for receiving the wireless speech signal and producing a received signal;

    d) a processor connected to the control unit for receiving the received signal and producing at least one processed received signal, the processor using parameters to generate the at least one processed received signal according to a selected mode from the at least three output coupling modes; and

    ,e) an output stage comprising a speaker with a coil, and further comprising an additional device telecoil, the output stage configured to generate the at least one output signal based on the at least one processed received signalwherein the at least one processed received signal is provided to the speaker and not to the additional device telecoil when the selected mode comprises the microphone mode;

    wherein the at least one processed received signal is provided to both the speaker and the additional device telecoil when the selected mode comprises the microphone/telecoil mode; and

    wherein the at least three output coupling modes correspond to modes of input operation for a hearing aid to improve coupling between the device and the hearing aid.
