We have successfully invented and patented two important tools for commercial vehicle and heavy equipment operators.

* Ear Mounted microphone and speaker.
* Radio interface (push-to-talk keying circuit).

Our headset IP provides a first of its kind adjustable ear-speaker along with important ergonomic comfort features which are unmatched in present headset designs. A hands-free microphone system for CB radio does not currently exist. Mic-Master is busy developing advanced product from our original designs.


There are approximately 4.5 million commercial vehicle operators per day in the United States who use CB radio, including heavy equipment operators, front loader, backhoe & excavator operators, agriculture & forestry machinery as well as Off-Road Vehicles.

The radio interface hooks into a conventional CB radio replacing the traditional hand-held microphone. This radio interface allows a headset to connect to a CB radio. Our IP provides for a single design to be used with multiple brand radios.

Approximately 1 million CB Radios are purchased throughout North America each year.
