I recently was fitted and purchased some outstanding ReSound Aids. The PhD Audiologist was fantastic. I go back tomorrow for some quick reporting in to her and tell her any changes I wish to make. My level of loss is moderate/severe. I honestly don't think they could be more effective. I was totally surprised with how much improvement they provide. I think I'll leave everything as is this time around. The most amazing thing for me is the ringing in my left ear (which is very loud and distracting) is almost forgotten while I wear these. The low end distortion and drone is almost gone too (when wearing the aids) and I can hear some things better than I have in years. My mood has changed and my energy is higher again. The technology and skill combination of my Doctor and Audiologist has completely exceeded my expectations. Julie's advice is spot on.
