Everything I have found on the web so far is how to spot fakes. I don't even care if they are fake. I just want to know how the sound compares to a normal set of headphones. I would never buy the real thing, because I don't like noise canceling headphones anyway. I just want a set of cool looking headphones for a cheap price. So far the cheapest price I have found them are $40. If the sound and build quality is reasonable, I'll pick them up.
