Jill finally got up the nerve to ask me if I’d ever thought about getting a hearing aid. "No way, "I said. "It would make me look 20 years older. ""No.no. "she replied. "This is entirely different. It’s Crystal Ear!"

And Crystal Ear is super-sensitive and powerful too. You will hear sounds your ears have been missing for years. Crystal Ear will make speech louder, and the sound is pure add natural.
