The IIC style of hearing aid is the smallest style. It sits discreetly inside the ear canal, so it appears almost invisible to the eye. If you’re looking for a super-discreet hearing aid and have a mild to moderate hearing loss, this could be a perfect solution for you.
ITC is the most popular form factor within custom hearing aids. In addition to more options available such as dual mic (directionality), ITC has wireless functionality, which can connect with smartphones and stream phone calls and music directly to the hearing aids.
ITE is the biggest form factor within custom, but it then covers up to severe hearing loss, and has most of the advanced features such as ear to ear communication, wireless connectivities, MFi, etc. This model is available in half shell and full shell, half shell seems to be the popular device as it is smaller.
MIH is a unique solution which only ReSound offers. MIH was designed to provide the most natural sound quality and collects sound in the most efficient ways using your own ears.
In MIH the microphone is taken out from the device giving several advantages:
• the devices can be built much smaller
• It’s a perfect solution for the wind in noise
• There is a lower risk of feedback as the distance between microphone and receiver is further than normal custom products
