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).
Miniaturized hearing aids that will fit into the ear canal. February 17, 2014. Fraunhofer researchers pack a total of 19 hearing-aid components (left) into their new microsystem (right). System-on-chip integrated circuit, high-frequency filters, and other components are all fitted into a space measuring just 4 mm by 4mm by 1 mm.
