A portable case is disposed adjacent the wearer's ear and a wireless device is attached adjacent the wearer but spaced from the portable case. A transmitter of a transmitting circuit for transmitting the output signals of the ear microphone is housed in the portable case. A receiver of a receiving circuit is housed in the wireless device and receives signals from outside the system. The transmitting and receiving circuits provide a wireless connection between the portable case and the wireless device permitting two-way communication through one ear of the wearer. | |
