I too recommend the costco hearning aids but stick with the "high end basic". By that I mean a hearing aid that does a really high quality job of simply flattening your response curve out. That is what I have now. Mine are 3 years old. I love them. Music sounds much better--natural with the gaps filled in... So I went to costco to get the "latest and greatest" as a upgrade. I bought the Rexton that has a music mode.
Hated it. It has all kind of AI that decides what I want to hear instead of just sending me everything with the gaps amplified.
even in music mode is is doing a lot of digital signal processing. I've yet to figure out what model I'll try next.
