Provenance
The H-78/AIC headset was introduced around the same time as the H-75 helmet headset for use in aircraft equipped with the AIC-10 intercom system. Like the H-75 it uses the H-79/AIC earphone element (except the H-78C/AIC which uses the H-143/AIC). The boom mike used on H-78()/AIC is the M-33/AIC or M-33A/AIC that can also be found as helmet mounted.
