Is your issue sensorineural (auditory nerve) or conductive? If conductive, a bone assisted hearing aid (BAHA) may be appropriate, and much simpler than a cochlear implant.
I have a power aid in my right ear, with custom molds in both ears. I also have blocked the vent in my right ear. this boosts bass response, but may impede hearing voices. Works well for me.
I also have a Cochlear brand Osia BAHA. The damn thing is terrific. I only use HA’s for playing my classical guitar and live concerts, along with the Osia. but my auditory nerve is perfectly fine.
