The system comprises an ear-piece (2) and an intermediate module (3) connected to the mobile telephone (1). The ear-piece and intermediate module communicate with one another in half-duplex transmission under the control of the ear-piece via a wireless radio link at a frequency of less than 1 GHz, preferably at 434 MHz. The audio signals from the telephone or the ear-piece are converted into digital form before being transmitted by a digital transmission-receipt circuit using phase modulation. The transmitted signals are reconverted into analog form before being applied to a receiver (4) of the ear-piece or to an audio input of the telephone. A control button (19) located, on the ear-piece can enable the ear-piece to be powered on, the telephone to be remotely connected and disconnected, and a microphone (5) of the ear-piece to be actuated when the microphone is telescopic. This system enables hands-free use of the telephone without any health hazards.
