The adapto's, which I wore for years, are a 2 program digital hearing. In my case the two programs I had were the listening program and the telecoil. My adapto's were at least 5 yrs old, when I got rid of them a few months ago. The adapto's have the ability to automatically reduce background noise when they detect someone is speaking to you. The adapto's were good aids for their time but have become outdated due to all the newer technology. I'm not even sure Oticon makes them anymore.
