i bought these as NOS to replace a very well used hd545 that i much loved. b4 it arrived i found a hd565 on ebay and got that. so the hd545 stayed in the box (i tested them of course)
these are the most comfy headphones ever made- sound is great- blows away a modern hd555 noticably. i have heard these use the same drivers as hd565/580/600. i can tell you they are almost indistinguishable from the hd565.
these are 150 ohms so need at least a cmoy amp or a strong sound card
