Please do more research on the CI. I wish I had my hearing aid back. Music will never be the same again. The CI can never replace what those little hairs in our ears do. There are newer and better hearing aids coming. It's a long and gruesome process getting the benefits from the CI. Unless you are totall unable to use a hearing aid, approach this procedure with caution. My two hour surgery took three hours. I never knew that bacterial meningitis was suspected to be the cause of my hearing loss, until the surgeon was doing the implant. I picked the oldest company's processor, turns out if I had picked a different manufacturer, it would not have fit, due to the bone regrowth. It's been a total nightmare, I have endured depression, rage and a lot of anger, since the surgery. Good luck.
