IASUS GP3 Basic - Regular Size (12 to 17” neck sizes) - a throat mic system specially designed to allow for motorcycle riders and professional motorsport racing teams use hand held radios in noisy environments.

All iASUS throat microphones utilize Noise Terminator transponder (NT3), which is based on technology developed by the military during WWII. Most typical headset communication systems rely on the conventional boom microphone, which uses air as a medium of sound conduction. This traditional method is ineffective in extreme conditions such as high-noise and high-wind environments. The iASUS NT3 picks up only voice signals by absorbing the vibrations generated from within the user’s neck, without using air as a medium of conduction. The transponders are able to effectively eliminate the transmission of anything other than voice signals. The result is direct voice communication free from environmental and wind noise.
