Open-Fit Hearing Aids has a few primary benefits:

Because the ear canal is left open, low-frequency sounds come through with much greater clarity.
Hearing aids that block the ear canal can cause the user to feel their own voice is somewhat distorted or muffled due to the blockage. Open-fit hearing aids do not have this drawback.
Given their small size, they tend to be less susceptible to blockages due to earwax.
There is little to no telephone feedback when using an open-fit hearing aid.
They can potentially be a good fit for individuals who are somewhat sensitive about their hearing impairment, as they are less immediately noticeable.

How Do Open Fit Hearing Aids Work?

An open-fit hearing aid functions in essentially the same way as any other assisted hearing device. The hearing aid picks up sounds through a receiver, located either on the main body of the hearing aid or within the ear. This sound is then fed through an amplifier, and then finally sent through a speaker.
Coupled with recent advancements in digital feedback suppression, this allows open-fit hearing aids to function with a remarkable level of clarity.
