1. What CI brand are yours?
It doesn't really matter. If you don't train your brain, any CI is not going to go very far.
2. Can you have a conversation on phone? for many times have you been using telephone since your first CI activation?
No. I am 15 months post-activation. Daily one hour therapy should enable me to use the phone after five years provided I continue to train my brain. I am auditory prelingual.
3. Have you ever got any dizziness during being a CI users?
No.
