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).
The ear has three main parts: the outer ear (including the external auditory canal), middle ear, and inner ear. The outer ear (the part you can see) opens into the ear canal.The eardrum (tympanic membrane) separates the ear canal from the middle ear.The middle ear contains three small bones which help amplify and transfer sound to the inner ear.he inner ear contains the cochlea which changes sound into neurological signals and the auditory (hearing) nerve, which takes sound to the brain. Any source of sound sends vibrations or sound waves into the air.
