Listen Through Walls Device The listen through walls device works by amplifying the vibration of audio. When someone talks in a room they are putting out audio-waves that will be detected by the spy listening device. The sensor on the listening device senses the vibrations hitting the walls and amplifies them so you can clearly hear the conversation going on in the next room. This is the best way to listen through walls. Whats Included
