No, I know nothing about those hearing aids. My first hearing aids were fit in the 1970s. They've come a long, long way since then. But they are still 'aids' to hearing. They are not miracles, nor cures. Nor are cochlear implants. I still use one hearing aid with my CI. If/when I can use my telecoils with both my word recognition is close to 100%. With only one or the other it's far less as my brain has learned to mesh both technologies. If I could only use one though, it would be the CI.

The price you quote sounds fair. I hope they work well for you.
