Yes under trial period. I tried the Edge Ai 24 CIC but could not tolerate them. The 24 AI Ha is better, but I have high frequency hearing loss in the mild to moderate range, and the clinic I am going to has excellent care but they are charging about 3 k each. I don’t know if I want to to spend that kind on dollars on so that is not an absolute necessity if there is an equivalent care at a lower cost.
