IASUS GP3-Basic L (for large neck sizes - 38 to 55cm collar size) - 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, 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 Gen 3.0 Noise Terminator transponder picks up only voice signals by absorbing the vibrations generated from within the user’s neck, without using air as a medium of conduction. In doing so, 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.
