Hearing aids are electronic instruments custom-fitted to a person's ear for sound amplification.
They are completely portable and easy to wear, the entire amplification system being encased either in or behind the ear. The newest and smallest hearing aids available, these fit deep inside your ear canal and are practically invisible. Small enough to fit almost entirely in your ear canal, they are hardly noticeable. These are one-piece aids customized to fit within your ear. They are the most widely recommended hearing aid style.
