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. Miniaturization tech could also be used to monitor pulse, blood-pressure, glucose, ECG via wireless, be used in implants, pacemakers.
