This is the first time I’ve worn hearing aids. Bought them at Costco, I am confident of the way I was tested, the way my aids were adjusted. I would have to say that with them my hearing is better than when I was 30, mainly because all the adjustments I can make from my iPhone to them. For instance, was in a restaurant and the band was so loud you couldn’t talk. I cut out the back microphones and narrowed the front pick ups and could make out anyone talking at the table simply by looking at them. Also the biggest improvement was in knowing what the other person said. When my wife says I need a heating test, I here that, instead of you need a hairy chest. Plus, both of them cost what others have paid for just one. And they are not just amplifiers. Try them, you may be amazed what you’ve been missing.
