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 consists of the external ear canal, middle ear, and inner ear. The middle ear is separated from the ear canal by the eardrum. The middle ear contains the malleus, incus, and stapes, which are also known as the hammer, anvil, and stirrup. The inner ear contains the cochlea, which is the main sensory organ of hearing. The Eustachian tube runs from the middle ear to the area in back of the nose.
