All the components are located inside a small shell. This is inserted into the ear like an earplug. Some devices have an antenna-like plastic tab to ease removal. In-the-ear hearing aids are self-contained units. Volume can be adjusted and programs can be selected by remote control. Many models can be connected wirelessly to electronic devices such as mobile phones and TV sets.
These hearing aids sit more or less inside the ear. There are different types of ITE hearing aids:
- Concha devices, which sit inside the concha.
- Ear canal devices, which sit further inside the ear canal.
- Completely invisible models: Completely-in-canal (CIC) devices.
