The Sonic Super Ear is a small device that gives a 50 decibel gain over standard hearing. It is small, only needs one AAA battery, and includes a headphone jack for super-stealthy listening. ThinkGeek seems to think this device is for listening to lectures or nature sounds, but don't kid us. The Sonic Super Ear is for espionage, straight up. $40.
