Receiver in the Ear (RITE)
RITE devices (also known as RIC devices) are similar to BTE devices. The main difference is that with a RITE device the receiver sits in the ear canal. The RITE devices are the most common devices because of their ability to fit a wide range of hearing loss and ease of use when putting it in the ear.
BTE devices are designed to fit more severe hearing loss and are typically larger in size. The top image shows the BTE with an ear mold which provides a better fit and sound for those who need it.

In the Ear (ITE)
Full Shell (FS) and Half Shell (HS)
ITE devices fit the ear fully and are a bit larger than CIC and ITC so they are a little easier to insert and remove. They also are able to accommodate more options and features such as volume control and directional microphones.
