Well, it's been a good while since my last post on this issue, and i am trying to get used to the Widex (top model) for music. I must agree that there may be more that I don't like than I do. There are many music programs though that may help with this experience. In the end, frequency adjustment is only the beginning of correction, and I couldn't tell you about the other aspects of this device. It has been two weeks so far, in general, yes they do their job, but it is almost tempting to get a 33 band EQ that may sound better and do it that way. I do have my hearing tests starting from an early age to present. I used to have Superman hearing, and as cool as it was, it also could be quite annoying.
