Put me down as a fan. I took my son over to Best Buy to spend his x-mass funds. So we did a little session of trying EVERY phone in the store. And the Koss came out on top, For his budget anyway. The build quality is amazing and it sound just as good. A little pulled back in the mids for me but it's not bad at all really. For sure a budget king at $80 smackers.
But for me I'll be picking up the HD558 :) Those things sound Fantastic!!!
Good choice, I love the 558's :)
