The lightweight headsets were originally designed for use with commercial speech recognition computers. They are manufactured with PBT, the same material used to make automobile bumpers and are built for rough industrial environments. Monarch headsets feature a slender backband that offers a unisex fit. They are equally at home on the floor of a TV studio or inside the cab of a tower crane. Monarch headsets are available for almost all communication devices. They are especially popular for use with existing wireless systems, as well as Eartec brand receivers and all hard wire intercoms.
