Headset Microphone H-78C/AIC

The Headset Microphone H-78C/AIC, manufactured by Roanwell Corporation, is a classic piece of Cold War–era military aviation communications gear. Designed for use with the AN/AIC 10 intercom system, this headset provided clear voice transmission in the high noise environment of mid century U.S. aircraft. These systems were widely used by the U.S. Air Force from the 1950s through the Korean War period.
