The Pro Extreme Contact Microphone. Stick this Israeli military designed kit to any surface with special putty and pick up the sound of your neighbour’s nose hair growing. Or something. $395.00.
The small acoustic “super sensor” pick-up is placed against any surface and all sound vibrations will be amplified up to 100 times via the included portable 1 watt RMS amplifier and fed into specially manufactured perfectly matched active noise cancellation stereo headphones. The result is truly incredible. Don’t be misled by other contact microphones available on the market. This mic set is professional quality.
