I've had the top-model over-the-ear oticon's for a year. The before and after with music is like taking off a shirt draped over my speakers. More detail, more clarity,... Of course, you lose the opportunity to offer "sorry, I didn't hear you" as an excuse... I had one problem. I have dry skin, and in the past several years my ears have become itchy. Hearing aids don't help that. Perhaps I rubbed my ears too much with the aids in, but I ended up with a mold infection in my right outer ear. I was in Vienna when I finally went to a doctor, who said I had a Pilz - a mushroom, in my ear. Three otolaryngologists in two countries and four months to get rid of a sequence of such infections, and three months not wearing my hearing aids. The otolaryngologists all agreed that one can wear hearing aids too much, which is the opposite of what my audiologist said. Now I put a touch of baby oil at the opening of the ear every night, and rinse my ears mornings in the shower: The itching has abated (but not disappeared), I'm comfortably wearing my hearing aids, and enjoying the music.
