Description
The MinusNine VSB wireless earphone is a revolution in covert communications technology with a physical profile so small that it can be fitted deep into the ear canal making it imperceptible by others as well as comfortable for use in the most challenging special operations. MinusNine VSB exploits a technology called Vestigial Sideband Modulation to transmit audio signals over a short range from a neck loop or flatpack without responding to power or data borne interference. This (patent pending) technology is unique in this type of device and not susceptible to eavesdropping or external masking keeping communications secure and reliable. A range of neckloops and shoulderpads are available which can include PTT switches and microphones as well as a car loop amplifier.
