Wow. I am struggling with clarity and excited to read your post. I purchased NuEar hearing aids in December of 2017 and I meet with the hearing aid guy as often as I feel I need to which was every 2-3 weeks initially and then we would go for a month to 6 weeks in between adjustments. I have Meniere's so my loss fluctuates at times. The hearing aids provide the volume but clarity continues to be an issue for me. My job depends on being able to hear people and I get very frustrated some days. I like your idea of having different programs to try. Thank you for sharing your ideas!
