I wonder if that's the same lady who wrote on her blog that her CI was worse than her HAs. I made a thread on that and the concensus is she had unrealistic expectations and also probably too much residual hearing and was still getting benefit from HAs.
Ive read many CI blogs and talked to a few CIborgs online and those who are profoundly deaf, the majority of them don't hear the "same" as HAs, they hear much better!
However it's a different story for the few who were just HOH who got CIs. If I had as much residual hearing as they did, id hear better than CIs with my HAs. Id also hear some sounds unaided!
