In the price range you were looking at ($3500-$4000), you might look at Starkey and read up on their X Series RIC product. The X 70 should fall in that kind of price range.

I believe that you’ll find it remarkably superior in appearance. It has a dual nano coating for both oils and moisture (most good aids can resist moisture these days, but oil and sweat can still harm them because unlike the Starkey product they have a single nano coating layer, rather than dual).
I think the Voice IQ system will help in noise, and Starkey still have the most advance feedback cancelling system in the world.
Starkey is an American company, unlike the other mainstream brands that have been talked about.
Starkey is also sold as Audibel and Microtech, same product in a different box basically.
Of course it is hard to be specific without seeing your test results, but based on the types of aid you have been recommended already, I’d be surprised if the X Series wouldn’t work for you.
They also do that same technology in the Xino aid, which is the smallest of it’s kind in the world, yet has the same functionality as the larger aid.
