I am wearing Costco brand. I think Resound makes them. I have had several hearing tests. They all are about the same. One was by our friend who is a doctor and works for the VA and specializes in hearing/hearing aids. He said for the type of hearing loss I have, the Costco ones would be fine. They are good. He and everyone who has ever given me a hearing test has told me that I will never have "normal" hearing. It is good and I can adjust volume and for places with background noise, but, still not like it was when I was much younger. I have had periodic adjustments. They don't recommend a different set just yet, based on my hearing loss. Good luck with it.
