What is a hearing aid shell?

A hearing aid shell is the outer portion of an in-the-ear (ITE) hearing aid that houses the device’s electronic components. The term “shell” is also sometimes applied to hearing aid molds, which are custom-fitted earmolds that attach to behind-the-ear (BTE) hearing aids—but a mold is not itself a hearing aid. In-the-ear (ITE) hearing aids sit in your ear without any components sitting outside of or behind your ear. They’re custom molded to fit comfortably and snugly, whether they are half-shell or full-shell.

What is a full-shell hearing aid?

A full-shell hearing aid is similar to a half-shell hearing aid, but it completely fills the bowl of your ear. Many of the features of full-shell hearing aids are similar to half-shell models, but there are some reasons why people might choose one over the other.

Consider these full-shell hearing aid pros:

Versatility: Full-shell hearing aids are one of the most versatile options when it comes to custom-fit hearing aids.
Easy to insert and remove: Because full-shell hearing aids are larger, they can be a better option for people with dexterity issues
Secure fit: full-shell hearing aids offer a more secure fit than smaller options as they cover more of the ear’s surface.
Long battery life: Full-shell hearing aids tend to have a longer battery life than some other hearing aid styles
Best for severe hearing loss: Because of their more powerful amplification.

Here are a few full-shell hearing aid cons and other factors to keep in mind:

Easily visible: Full-shell hearing aids aren’t as discreet since they are more visible than smaller ITC options.
More prone to getting wet: Because full-shell hearing aids are larger than other models, they can be more prone to elements such as moisture, sweat or ear wax. Remember to keep them covered and clean them regularly.
Can pick up wind and other noise: Some users complain about full-shell hearing aids picking up whistling sounds from the wind since the device is larger and can be more exposed to the elements.

What are the differences between both?

When it comes to a half-shell vs. full-shell hearing aid, there are a few differences. First, half-shell hearing aids are smaller than full-shell. Typically, if you have mild-to-moderate hearing loss, a half-shell hearing aid will work well for you while a full-shell option will work better if you have more severe hearing loss.

However, both options have volume controls and other features that add convenience. Both options also often offer wireless connectivity to smartphones and other devices.¹
