I tried the el cheapo route for many years not wanting to shell out $3-6k for HA's. After purchasing many of them over the years I found that (at Amazon) the Britzgo brand worked well for me. Specifically the 702 BTE PSAP https://www.amazon.com/dp/B01M6V8TXV

and the BHA-220

Then I broke down and purchased a set of Costco's for $2k/pair.
