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).
These structures transmit sound vibrations to the inner ear. In so doing, they act as a transformer, converting sound vibrations in the external ear canal into fluid waves in the inner ear. The inner ear chamber contains tiny hearing and balance nerve endings bathed in fluid. The inner ear is a delicate, tissue-lined sense organ, which is encased in an outer hard bony shell.
