My 90 year old father went to the North Hills Zounds store to try their hearing aid. He has been hard of hearing for many years, and has tried hearing aids from many different companies. He was very impressed with the thoroughness of the hearing exam he received here. He tried the Zounds hearing aid free of charge for several days. Unfortunately his hearing is so far gone, that he could not be helped. But my dad was very impressed by the state-of-the-art product, and the compassion and helpfulness of the people here. He highly recommends this place.
