As the name implies, in-the-canal (ITC) hearing aids fit in the ear canal. They are slightly larger and extend a little farther out than completely-in-the-canal (CIC) hearing aids. However, due to their slightly larger size, in-the-canal (ITC) hearing aids can fit more features than CICs. Like CICs and ITEs, ITC hearing aids are custom fit for your ear. Wearers may choose from a variety of flesh-toned casings, making them difficult to notice.
