How to use:
Simple, you switch on the Wall Listening Device, insert the earphones, and then place the audio bug on the wall and listen to what`s being said. This audio gadget works by amplifying the vibrations of audio. When people are talking in a room their voices are simply a waveband, and depending on how loud they are talking, the waveband travels short and long distances which are picked up and amplified by this device. The sensor on this audio gadget senses the vibrations hitting the walls, ceiling and floor and amplifies them so that you can listen to whats being said. If the waveband is low, meaning people talking in a lower note, then you can use the dial located at the back of this cool audio gadget to adjust the volume and increase the sensors amplification.
