Hrm, I've never heard of that before. What frequencies are bad exactly?

I'm talking about the middle frequencies, you know? But now that I've used the EQ, I can tell you can do what you want with this little unit and fix any problem you may have with your pair of headphones. It is simply superb in sound quality.
I had recently travelled a long way, 7 hours to go, then 7 to get back, and all the 14 hours listening to some good, reasonably loud music… No problems at all! No headaches, no stress, no ear numbness, nothing. I enjoyed to the most, 14 hours of music!
No doubt, the iRiver trade for MP3 are of superior quality compared to most of the market!
