The present invention provides an in-ear-canal audio receiver (42) comprising an in-ear-canal adapter body (96) having a tapered ear plug portion (98) that is inserted into the user's ear canal. The adapter body (96) further has an opening (104) in the plug portion, an exterior annular indent (128), and an inner chamber (94) coupled to the opening of the plug portion. The inner chamber of the in-ear-canal adapter body holds a transducer assembly (92) comprising a transducer housing (54) and a transducer or speaker (56). The transducer (56) is positioned in a passage extending through the transducer housing. A torus-shaped cushion (106) is positioned in the annular indent of the in-ear-canal adapter body (96). The cushion provides comfort and establishes a good seal with the user's ear.
