I've been wearing ihear behind-the-ear hearing aids for 3 years now. When I bought them, I also bought the at-home hearing test kit to program the aids to my specific needs (one ear has much more hearing loss than the other). Anyone who buys any aid and doesn't go through a full hearing test to properly program those aids isn't seriously interested in hearing better.
I can certainly tell a difference when wearing the aids. Do they make my hearing perfect? No, of course not. Hearing aids simply amplify sounds in the frequency ranges they've been programmed to be sensitive to, and in preselected proportions. In a noisy restaurant, they will amplify all voices. Sitting in my quiet living room, I'm often amazed I can hear the clock ticking from across the room.
I've periodically ordered new supplies from ihear - mostly ear pieces which, from a sanitation standpoint, need to be replaced periodically. Never had any problem.
I've been satisfied with theses aids and the cost was far more reasonable than most places. Initially I did test aids at Sam's Club and Costco, and found their aids to be no better than ihear and more expensive (although still reasonable). read more
