Benefits of IIC hearing aids:
Invisible hearing aids are as close to invisible as you can get making them a great option for people who want to conceal their hearing aids as much as possible.
The position of these type of small hearing aids make it easier to use with your phone or a headset.
Protected by the outer ear, invisible in the canal hearing aids pick up less wind noise when you are outside.
Their location inside the ear canal can also reduce the uncomfortable occlusion effect that warps sound, and their proximity to the eardrum means they are less likely to produce feedback like whistling.
Potential issues with IIC hearing aids:
These types of hearing aids aren't suitable for people with severe hearing loss. For people with advanced hearing loss, a more powerful Behind-the-Ear style
usually works better.
IIC hearing aids don’t fit in all ear canals. They don’t work well for people with short or differently-shaped ear canals.
The battery life of very small hearing aids tends to be shorter than some of the larger styles—although, this technology is always improving.
The controls on these types of hearing aids can be harder to see and feel, and the batteries are more difficult to replace. So they are not a good option for people with dexterity issues.
