Listen Through Walls Listening Device

This listening device is as powerful as it is simple, and will allow you to hear conversations through walls and other barriers.

The Listen Through Walls Listening Device, operation is simple.  Insert the earphones, and then place the listening device on the wall and listen to what's being said.

This works by amplifying the audio vibrations. 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 then amplified by this device.

The sensor on this listening device senses the vibrations hitting the walls, ceiling and floor, and amplifies them so that you can hear what is being said. If the waveband is low, meaning people are talking in a lower tone, then you can use the dial on the back of the device to adjust the volume and increase sensor amplification.

• Simple to use
