I don't know who will purchase this eavesdropping device and this kit is good as its claim. The Next Room Eavesdropping Device($62) looks a bit like the business end of a stethoscope, but uses an electronic internal sound amplifier to boost the noises coming through a wall, door, window and even steel plates. It includes a set of a set of headphones, built-in rechargeable battery charge via USB, ON/OFF Switch Button with volume Dial.
