Lol thanks for the help. Not really loving the look/style of the Pioneers. Also a little concerned over the amount of bass in them, but as you said, they do have a built in equalizer. Do you have any input about the headphones I listed in my first message as I found those to be reviewed the highest?
Regarding your list, it's hard for me to gauge which one is best since I've only heard the Sony V6 - a very boring headphone, not good for rap.
I think the Superlux and Panasonic have a more musical presentation, but I've heard both good and bad things about them. Again, I can't comment here since I haven't heard either.
Some other <$50 headphones I have heard, are the Koss Pro DJ100 and the HARX900, and I highly recommend both. But IMO you won't find much improvement from the HD428 under $50 - the HD428 is already a highly-regarded budget-fi headphone to begin with.
