One day a friend asked my wife Jill if I wanted a hearing aid. “He certainly does,”replied Jill. After hearing about a remarkable new product, 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!”

Jill was right. Crystal Ear is different –––– not the old-styled body worn or over-the-ear aid, but an advanced personal sound system so small it’s like contacts for your ears. 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 and natural.

I couldn’t believe how tiny it is. It is smaller than the tip of my little finger and it’s almost invisible when worn. There are no wires, no behind-the-ear device. Put it in your ear and its-ready-to-wear mold fits comfortable. Since it’s not too loud or too light, you may even forget that you’re wearing it! Use it at work or at play. And if your hearing problem is worse in certain situation, use Crystal Ear only when you need it.

Hearing loss, which is typically prior to teenage years, progresses throughout one’s lifetime. Although hearing loss is now the world’s number-one health problem, nearly 90 percent of people suffering hearing loss  choose to leave the problem untreated. For many millions, treating hearing loss in a conventional way can involve numerous office visits, expensive testing and adjustments to fit your ear. Thanks to Crystal Ear, the “sound solution”is now convenient. Almost 90 percent of people with mild hearing loss, and millions more with just a little hearing dropoff, can be dramatically helped with Crystal Ear. Moreover, its superior design is energy-efficient, so batteries can last months. Crystal Ear is now available to help these people treat their hearing loss with a small hearing amplifier(扩音器).
