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 and 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]
