I wear Phonak M90s, and the receiver is in the ear canal – RIC.
(“Receiver” is a confusing term for those of us who first used it for a piece of audio entertainment equipment; originally it applied because the primary purpose of that piece was receiving FM radio. For HAs, it basically means “speaker,” or more generally, “receiver of the output of the amplifier.”)
Also, for RICs the receiver doesn’t have to be in a mold. It can be, but it might have only a rubber dome attached.
