I am looking for headphones that are
-comfortable (hours of continued listening)
-sound isolating(as a frequent flyer, but I'll be on planes a lot of the time and I don't want too much leakage)
-on ear/over ear (I already have a $3 decent in ear set, not joking)
Preferably the price will be under $80 and at least under $100. I cannot afford anything above that right now. And they should at least be px100 quality. I bought those half a year ago for only $25 and they broke, so I died a little inside. And I'm not going to pay 3 times its price for a set of inferior quality.
