You were turned down for a CI, right? You benefit from HAs, you just don't find your HAs comfortable to wear all day if I read correctly? Ive seen some keep part or even all their residual hearing with CIs(but no guarantee how long they keep their residual hearing) while others lose it all. If your residual hearing is important to you, id stick with HAs. If you get CI and lose some or all your residual hearing, you can never go back to HA in the implanted ear.
I know a lady who got a hybrid CI a few months ago. She had alot of residual hearing in the low frequencies and was getting decent benefit from HAs even though they weren't full power or programmed the best for her loss. I wish I had as much residual hearing as she did(ill get my chance soon) but anyway she implanted her worse ear and lost alot of her residual hearing. She can't wear a HA in that ear. I personally don't understand why she wanted CI, she even was happy with HAs but her audiologist pressured her into a CI. Ok so she got a small improvement with CI in the speech range but she lost her ability to hear unaided or hear below 250Hz. She can't hear bass music in the CI ear.
