Hearing Aid Styles

Though small, and often invisible, hearing aids are powerful electronic devices that reconnect you to the sounds of your life and empower you with confidence in your abilities. Hearing aids come in many shapes and sizes, but they all share the same components: microphone, processor, amplifier, receiver, and battery.


Hearing aids come in many shapes and sizes, and the configuration of these components differ depending on the style of the hearing aid. The main hearing aid styles are:


In-The-Canal (ITC)

In-the-canal (ITC) hearing aids are a form of in-the-ear (ITE) hearing aids, which are worn deep inside the ear canal. These are usually custom made devices made to fit inside your canal, which gives them the benefit of being visually discreet. ITC hearing aids may be difficult for people with dexterity issues to control, while the lack of a directional microphone means they are better suited for people with moderate levels of hearing loss. They come in completely-in-canal and invisible-in-canal styles.



In-the-ear (ITE) hearing aids are worn inside the ear, with the shell of the hearing aid at the surface of the ear. The options are full shell or half shell. ITE hearing aids house all of their components in a plastic shell. While these hearing aids benefit people who wear glasses or experience arthritis, they may not be convenient for those who have dexterity issues due to their small controls.



Behind-the-ear (BTE) hearing aids are worn on the back of the ear with a plastic tube that delivers sound to a custom ear mold. BTE hearing aids are easier to control and treat a wide range of degrees of hearing loss. They may be inconvenient for people who wear glasses, but the placement of their controls will be easy for people who have dexterity issues.



Receiver-in-canal (RIC) hearing aids look like BTE hearing aids; the difference is that the receiver is worn in the canal. RIC hearing aids are discreet and treat a wide range of degrees of hearing loss. Like BTE ones, they may pose a challenge for those who wear glasses due to their placement.

Hearing Aid Manufacturers


Founded in 1967, Starkey Hearing Technologies is committed to their mission, “Alone we can’t do much. Together, we can change the world.” As the sole American hearing aid manufacturer, Starkey Hearing Technologies created the first in-canal hearing aid and first custom, digital and fully programmable hearing aid. Starkey uses evidence-based design and research to update their hearing aids, thoroughly testing them at the Starkey Hearing Research Center in Berkeley, California. The Starkey Hearing Foundation donates hearing aids to developing countries for every purchase made of a Starkey hearing aid; to date they have gifted over 1 million hearing aids.
