There has been a lot of reviews but I thought I would add one more experience.
I finally got my Sphere 90s after a long delay waiting for the correct cshells from Phonak. Last evening which was a Saturday, my wife, grandson (12yo) and I went to a local sports bar/restaurant for supper. The place holds about 75 to a hundred customers. This place has concreate floors with no sound deadening decor. It was jam packed with families, many with small children and teenagers. Adults were drinking beer or another beverage of their choice and the Mets/Phillies game was on one TV while the Yankees was on another and some were yelling and jumping up and down when the Mets did something good. In the past, with my L90s I would have just set quietly and ate my hamburger. With the new Phonak Spheres I was actually able to have a nice conversation with my wife without much problem. Wow!!
You can see from my audiogram that I have a steep hearing loss in the upper frequencies and I was using frequency lowering aggressively. So, so far I am a happy camper.
