Passport Moxiâ„¢ uses Canal Receiver Technology (CRT) to deliver sound into the ear canal. This method has a very small electronic component at the end of a small tube that is inserted into the ear canal. This component is called a receiver and produces sound very close to the eardrum.
Passport Modaâ„¢ II uses a slim tube to deliver sound into the ear canal. Moda II hearing aids keep the receiver inside the case. The slim tube is about the same size as the small tube on the Moxi with no difference in appearance.
