Next Room is kind of like a mash up between a stethoscope, MP3 player and an old fashioned drinking glass. According to the product page, you can hear what is being said through wooden walls, doors, windows—even steel plates.
It features an internal sound amplifier, a 3.5mm jack for headphones and a USB port for recharging. Nice, but if you really want to take this whole scumbaggy espionage thing to another level, you go with the SIM card spy ear. [Chinagrabber via 7Gadgets via OhGizmo]
