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).
Receiver in the ear (RITE) hearing aids. Receiver in-the-ear (RITE) (or loudspeaker in-the-ear) aids are often smaller than BTE aids because some part of the device sits inside the ear. Like open ear BTEs, they can be easier to put in than an earmould if you find fiddly tasks awkward. There are different RITE hearing aids for different levels of hearing loss.
