I started with a Dr.'s prescription for a test and a copy of the test report from an Audiologist.
I am lucky that Audicus has a NYC store I could go to, they have other locations, but not that many.

I took the 100 day risk free trial, and checked other options during that trial.
I joined Costco, because their hearing aid setup is very good, they now offer 4 brands (3 when I compared), the top models only. Price was significantly less than other sources.

The chargers and software you can control with a smartphone varies a bit.
My final choice was Audicus Omni Series 2, slightly more than Costco, they work best with my phone. After an initial period to get used to them, they were able to make an adjustment remotely.
