EAR-1
this eavesdropping device was used by criminals and spies during the height of the Galactic Civil War. Comprised of a button-sized listening device, a headset, and a receiver, the EAR-1 was a jet-black unit which stored away in an unobtrusive, small metal case. One of its major features was the use of a miniature damping unit, which prevented it from being detected. However, the EAR-1 had a very limited range, due in part of the damping unit, and the receiver had to be in a line-of-sight with the listening device.
