Different because one's open the other closed. I have the Grado HF2's and those are PHENOMENAL but need a good amp. I also have the 840's because I got them on a great deal for $125. Those are also good but closed. I like them so much I even travel with them despite the fact that they are enormous and a bit of a pain to pack. I'll take these over active noise cancellation any day.
