$6000 is a big investment. If you are not satisfied with the hearing aids you really have nothing to lose by returning them and then trying another brand. Maybe exchanging your audiologist as well since he/she said the aids would help the tinnitus and they did not. I saw a different audiologist two months ago and paid out of pocket for the evaluation ($125). Although she pretty much verified everything the first audiologist had told me I felt the second opinion was worth it for my peace of mind. Judy
