In-the-ear (ITE) hearing aids contain a microphone, amplifier and battery in a plastic case that rests inside the ear canal, making them less noticeable than even the smallest BTE devices. These are ideal for mild to severe hearing loss. These hearing aids still might be too large if you have small or narrow ear canals — in this case, BTE aids may be a better choice. Because of their size, expect to pay more for these hearing devices, typically around $1,000 to $3,000 per aid on average, though prices vary significantly.
