Very nice cans, very good price. Similar to the dt990s, with the main difference being these are closed backs, and the 990s are open.
Sells for ~$240 elsewhere.
Will need an amp to be used properly, you could opt for the 80 ohm version which is selling for the same price here for something a little easier to drive.

What a good amp for this?
