Yes, they do fit comfortably over your ear, and they sound quite good for their price range. As mentioned in the review, I think their best role is as tracking headphones, but you could use them for mixing, assuming you have another way to listen as well. You can't expect them to be as accurate as accurate as reference headphones that cost 3 to 5 times as much. That said, they have good bass response, but aren't overly bassy, which is probably a good thing for mixing hip hop beats.
