I got a cowon J3, Well not really worth it. But it was a good buy since it was a direct trade without any added cost.
My cowon is starting to die. The sound is good and the equalizer is very great and helpfull for some cheaper headphones. But the UI and everything else just sucks. Oh and battery life is a bliss on my cowon. Two weeks lifetime seems prety good
So prety mixed feelings there. The sound and battery is better but everything else sucks ass.
