This hearing aid has really helped to solve a big problem for me. I have hyper active hearing in one ear, loud noises, voices and sharp sounds are very distorted and this makes it very uncomfortable for me to be in bars and noisy places. Very unsetting and difficult as I am a singer in my profession! These aids cut that noise out and alow me to hear what people are saying and I can also hear my voice and music better. Completely life changing as now I can continue to do the job I love!!
