Thank y'all for posts with poll about yourself. Hearing aids is still leading over CI. I am definitely CI will be lead over HA in future. Who know.
That's unlikely to happen. First of all it's rare for someone not to have uesful hearing.
secondly, not all people without useful hearing will be able to use a CI.
While some people who have some useful hearing are attracted to getting CI's I don't think it's advisable since success with CI varies from being HOH to just hearing environmental noises. If you are successfully using a HA there is no need to get a CI.
