4 out of 5 eggsSolid headphones

Pros: Light, durable, good audio quality, good noise isolation, comfortable. Replaceable cord is a nice touch; lets you pick either a short cord for mobile use, or a long cord for home use. Cords/connectors tend to be one of the easiest things to break or wear out on headphones, so knowing that I can get a replacement if the worst should happen is reassuring.

Cons: NewEgg overcharges by ~$10 CAD after exchange rate. I'd much prefer if they were matte black without the shiny silver sides. It would be nice if the ear cups rotated 90 degrees to make them less likely to be damaged when thrown in a bag. A case would be nice; audiophiles might think $100 is cheap for headphones, but for a lot of us, it's a big investment for a set of cans.

Other Thoughts: A friend almost sat on them, and they survived without damage; they seem delicate when you first pick them up because they're so light, but they're actually pretty durable (probably because they can flex).
