Key takeaways
- Half-shell and full-shell hearing aids sit inside the bowl, or concha, of your ears without any components sitting outside of or behind your ears
- Half-shell hearing aids are smaller than full-shell

- Both styles have pros and cons, including their fit, size and functionality
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 half-shell hearing aid?
Half-shell hearing aids cover only the lower half of the concha. They are smaller than full-shell models while still offering a good level of hearing support.

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.

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
