Modern hearing aids work pretty well at least for moderate loss. I tried previous ones and they were not helpful. Have had Oticon OPN and now OPN S for the last 4 years and it's been transformative.

Still, it's software which you can't manage yourself. Any Oticon people on here, handling of the release of S w/ feedback shield issues with high pitched voices was done quite poorly.

There are some large and fairly extensive genetic panels that can be run within months now for a few thousand if insurance doesn't cover. Unfortunately they don't have the variants causing my loss. Looking at full exome sequencing at Stanford but insurance is balking and it's 10k.
