I have Cochlear implants for both ears, but only wear one for rides. Due to comfort reasons from the helmet's Roc-loc being tight around the magnets. For rides, I always wear my left one so I can hear the traffic and people saying on your left. I can't really carry a conversation anyways, so voices don't bother me. From my experience, it will take a while for your ears to get used to something foreign on them. Get double stick tape and put it on the hearing aids and stick it on the side of your head. I did this when I was a kid while I did gymnastics. They stay on. The helmet straps can accidentally "flick" the aids off, especially if you're not used to it. I'vehad that happened to me several times. Do this for a while until you feel comfortable with them.

How bad is your hearing? You probably can get away with cheaper versions, but they won't last you as long. Digital ones, you can have a couple programs for specific situations. One for everyday, one for riding (noise reduction due to wind), one for restaurant setting.

Know what's the really stupid thing is? Insurance companies are more than willing to pay a $40k or more for CI surgery, but won't pay for hearing aids.

Good luck and enjoy the newfound sounds. I know I did when I heard crickets for the first time at 29.
