KOSS KSC55 3.5mm Connector Supra-aural Portable Headphone


Killer Sound. Great lite-weight headphones... only problem is the unadjustable squeeze that it places right above your ears...

KOSS KSC55 3.5mm Connector Supra-aural Portable Headphone


HUGE fan of these headphones...very light and easy to stick in a backpack, plus they sound just as good as my $100 closed-cup Sennheisers (and these Koss ones don't have the annoying in-line pulsating battery thing that the Sennheisers have)! Great...

these headphones sound awesome, only problem is they're so tight, they hurt the sides of my head while wearing for more than an hour.
