I have been wearing Costco Signature 5 hearing aids for about 4 years. They have been adjusted a couple of times, about a year ago based on VA hospital audiologist testing, and most recently about a week ago by the Costco fitter. On this last time I again noted that when I put my left hearing aid in first the whole world of sound opens up, yet when I put the right hearing aid in I get only a modest improvement in hearing. He said, (I think the word used) I have profound hearing loss in my right ear, that is the ear simply can’t hear high frequencies even when amplified. Looking for advice and experience, the problem as described seems plausible and I trust Costco enough to believe the fitter had nothing to win/sell by telling me the facts. I also did a test walk on Signature 8, just around the store and only in automatic mode, I did not find any significant improvement over the Signature 5 in this very simple test. I will most likely purchase the Signature 8 or its replacement when I hit the 5 year mark.
My main complaint with hearing as aided by Signature 5, is I have a lot of difficulty understanding speech in noisy environments. and especially on the complex HDMI sound track on DVD/BlueRay movies played on my tv setup. I have a sound bar that tries to give me better voice and I notice the improvement, yet the speech is sometimes still hard to understand. Perhaps a program/feature on Signature 8 would help here, i.e., Bluetooth audio directly to the hearing aids?
