It would be nice to see what your audiogram looks like in your profile.
It’s kind of weird that your description of wearing the 9040 sounds like a new user who hasn’t worn hearing aids before, yet you’ve worn the KS10 before that, meaning you notice the click of the keyboard or the beep of the microwave oven, and the shrills from female voices, the clattering of plates, that the world is a much louder place, etc. I didn’t expect the difference going from the KS10 to the 9040 would be that dramatically different. I thought maybe their performances for speech in noise might be different, but you should have heard the details that you didn’t hear before on the KS10 as well. It looks like the amplification of the highs are dramatically different between your KS10 and your 9040.
