Unlike standard headphones, which use relatively large drivers (speakers) and fit on top of or around your ears, or earbuds, which use fairly small drivers and sit loosely in your outer ears, in-ear-canal headphones use very small drivers and actually fit inside your ear canals (thus the name canalphones).
What are earmolds? Earmolds are the plastic part of your BTE hearing instrument which connect the ear canal to the hearing aid and literally place the sound in your ear. Depending on the type and degree of hearing loss, and the anatomy of the ear, the earmold can be canal size (tiny), half-shell size (medium) or even a ''full shell'' size (large).
