I am here because my Koss portapros just broke. I have gotten them fixed before, but this time it was my fault, so I doubt koss will repair them for free. I was looking to make this an opportunity for a small upgrade. My goal is to buy something in the $80-$100 range. From the little bit of research I have done the top picks seem to be UE 6000 and Harman Kardon CL which both are about $88. I was attracted to these because bass is important to me and they seem like strong choices for that. Can someone recommend or argue for one over the other? Would I be better off with ProDJ100s or Creative Aurvana Live? Thanks for all the help!
