Pros: Price, Sound, Retro Design
Cons: Bass Boomy and slightly Muddy, You get what You pay for
Fantastic cheap Headphones despite the bass. However do not expect them to sound as stellar as people rave them to be. The are a great deal for people who like bass heavy heeadphones and dig the design. The adjustable slides pich hair and they leak ALOT of sound. If you like lots of bass, like the quirkey design, and have no money, then go ahead buy 'em.
I have the REOs and love them. I listened to my friends Koss.
