A wireless communications headset system for double hearing protection systems that eliminates the problems associated with typical wireless communications systems. The system employs a magnetic-field coupled wireless link from a loop transmitter to a magnetic field receiver. Current through the transmitter wire loops generates magnetic flux which passes through a communications earplug. The earplug has a receiver for converting the magnetic flux to electrical voltage, and this voltage is used to drive a speaker within the earplug. The transmitter can be easily installed into aviation headsets. The loop transmitter has an open center sized so that it fits around the pinna of the human ear enabling a close position to the communications earplug. This close position is advantageous if an efficient system is desired.
