I realize this is mostly a personal preference but I find myself sifting through the lot without settling on a favourite. I have quite an ecclectic music selection but I'd have to say the bulk of my listening is with rock bands from the 60s - 80s. I listen through my car stereo and I have some Koss and Skullcandy headphones for any other time. Do most folks have a preference or just leave the EQ off? Any suggestions?
