I am not having much success finding a local audiologist to reprogram my Costco K8.0 Rextons. I may have to fly to Southampton! However a very helpful local said that more sophisticated hearing aids that can be controlled via an IPhone (as mine are) can sometimes be reprogrammed remotely via the IPhone. She can provide the necessary audiogram and said that this approach is becoming more popular in the Covid era. Wow! Does anyone have any related knowledge?
