Spy Gadget Listen Through Walls Monitor Hearing Aid

Strong penetrability and high sensitive let you hear the sound from the next room fully. This audio gadget works by amplifying the vibrations of audio.

The sensor on this audio gadget senses the vibrations hitting the walls, ceiling and floor and amplifies them so that you can listen to what being said.
