I have been using the Uni-Dex device for hearing the human voices produced by a program called ZoomText for people with low vision for more than a week, and think it is a remarkable device. I also use it to hear my mail on my I-Phone. The clarity of the voices is remarkable, and it has enabled me to store my Bose earphones away. It is light, slips over my head easily, and has little or no weight, so that at first I forgot I had it on, and pulled the amplifier with me when I walked away from my computer. It is really an impressive advance in hearing technology, and I can recommend it without reservation.
Thanks very much for making it available for me,
