|Spy Sound Amplifier|
The Spy Sound Amplifier (called the Spy Amplifier Sound on the box) is a 2013 Nerf N-Strike product. It is supposed to allow one to hear what others are saying. Although it is probably not going to be incredibly useful in a Nerf War, it is good for the fact that it allows one to hear enemy tactics. It also includes a pair of earbuds, which are also found separately. The Spy Sound Amplifier can also be found in the Action Kit, along with the Movement Detector.
