Pros: Cheap, Somewhat comfortable, good mids and highs
Cons: no bass whatsoever, gets uncomfortable after a while, leatherette material
these are cheap, price and buildwise, but deliver decent sound quality. The bass is pretty much nonexistant, but the mids and highs are good. The one flaw I saw was the leatherette ear pads that are very prone to flaking off or tearing. They aren't bad for the price, and if you need a pair of cheap, replaceable headphones, I would recommend them.
