J used this headset for about 3 months, the look is a bit of a collector, comfort is of good quality, for it is its just wonderful, for me it is more than the hd 600, hd 600 is certainly the very arérien but at the expense of involvement of the same music, the seating in the low 580's HD as well as slightly centered listening is very nice, do not scrap the acute and the medium is never good enough, this headset deserves the best, is to say c a good cd, good cables, and a very good headphone amp in the price range of 200 to 350 euro here is the best headset that I have to listen, there Occasion ad on ebay around a hundred euro, this c price is a bargain.
