I wore a CIC for a few years, and I don't think I would go back to wearing CICs, because they are expensive to maintain.
My hearing degraded three years ago, and if I recall, my CICs would not give me good hearing. So I decided to get a new HA that sits inside my ear, but it is not CIC.
The funny thing about wearing CIC, is that people ultimately notice the HA, and often ask me what is inside my ear. With my current HA, nobody has questioned my HA, which is better, because I don't have to explain anything and talk about hearing loss, etc.
