The cans don't look full sized. They look more like a gussied up AH-D1001. I'm guessing they wanted to keep them small enough for portable use, to reach the largest audience.
Edit: It does say over ear, so I guess I'm off base.
Second Edit: Looks like a gussied up AH-D510R. I hope wood isn't the only upgrade at a $500.00 price increase...
