Thanks for all the feedback.
I did a search on HearUSA and was NOT happy with the results. Sounds like a disaster with bankruptcy and all kinds of financial shenanigans.
The HearUSA on site Rep said that they can get other brands, but said they do the vast majority of fittings are done with Signia HAs.
It just chaps my hide to pay more out of pocket with my significant Kaiser benefit than Costco charges. It feels like I’m getting old technology as the first of the Nx HAs were introduced in October of 2017. The service better be significantly better than Costco or why bother with the added expense?
I think I am going to try the 7Nx with the Sierra recommended DSL v5 fitting formula for the trial period. If something new comes out, or I don’t like the sound, I may demand a change in device or office.
