In-the-ear hearing aids
The largest custom hearing aid style is called in-the-ear (ITE). An ITE hearing aid is usually custom-made in two styles — one that fills most of the bowl-shaped area of your outer ear - this is called a full shell - and one that fills only the lower part - which is called a half shell. Both types of hearing aids are helpful for people with mild to severe hearing loss and are available with directional microphones, which comprise two microphones for better hearing in noise.
An in-the-ear hearing aid includes features that don't fit on smaller style hearing aids, such as volume control. They may be easier to handle compared to CIC and ITC hearing aids.
