I disagree. From the research I have done, people with some hearing have significantly better results from a CI than they do with HA's. CI results from those with little to no hearing are not quite as impressive.
That's why I specifically said "Wearing hearing aids in a partially-deaf ear probably will give you the same results as a CI"
In other words....if someone is HOH and can understand speech with a HA, they are not going to benefit that much more with a CI.
We can argue all day over details....before that..do you have CI's? I have two, have been wearing them for 10 years now, and wore HA's for 30 years...how about you?
