As simple and powerful as possible from a handheld listening device, this audio spy gadget can let you hear conversations through walls and other barriers. So how does it work? Simple, you switch on the Audio Listening Device, insert the earphones, and then place the audio bug on the wall and listen to what's being said. This spy 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.

Best to use on wooden walls, doors, windows, steel plates, etc.!
