@capausz Mine are Oticon Opn1. They have just come out with a later model, OpnS which is supposed to be significantly better for clarity -- 15%. I believe when I got them they were supposed to be around $3400 each but I paid $3000 each -- I've been with that group for a very long time.
When they test your hearing, they test the volume and frequency to determine where your loss is, and then they test your comprehension but saying words that you have to repeat (they are in a soundproof glass booth with something covering their mouth). It was there that I had a huge problem. My word understanding was terrible. I think in some frequencies it was around 40%. My hearing loss is the worst with high frequencies. Less common is loss of hearing low frequencies. That's called "reverse slope" because the graph or your hearing is reversed, going uphill rather than downhill.
