I'm profoundly deaf, and I can answer these questions for myself:
> Do you charge on ear at a time so you are never without some level of hearing?
I'm completely deaf in one ear, so I only wear one hearing aid. If I take it out, I have zero hearing, so... nope.
Most hearing aids do not have rechargeable batteries, either, so we have to change out the batteries on a regular basis. My battery lasts about 7-10 days before I need to replace them.
> Can you comment on the Live Listen feature of AirPods?
It's not powerful enough to act as a hearing aid for my level of hearing loss, nor is it calibrated correctly.
To that last point, hearing loss is not simply a lowering of volume. It impacts different frequencies at different levels, so the normal amplification that comes from an AirPod or similar headphone is not sufficient to compensate for anything other than very very mild hearing loss.
