Purchased hearing aids at HEAR USA in Ocala RT 200 for over $3000 plus insurance, WORST condescending hearing aid ( specialist?) I have ever had to tolerate. When I told her there is a chirping noise when I chew, she says "then don't chew"! In the beginning of 3rd visit I asked if she could give me the circular inserts because they fit very comfortable vs the rectangular ones. She told me they don't have them. The 5th and final visit on Monday I will be returning them for a refund which my insurance company has agreed to. All of a sudden they have circular ear piece?
