That is very interesting to "hear" about. Since I am searching since years for hearing aids and fitting just fails. I am expecting that it is dependend on the temporal delay of the processing of digital aids? Since the intelligibility is most often very high in the beginning of wearing a new aid, but dissapears after about two hours. Recently I would like to test the synchronisation ability of my hearing. In case you are having any further information of how to solve the problem, I would be very thankful in finding back to easy listening. Yours sincerely Stefanie Richard F.
