1) Haven't heard this one
2) I believe it's the same as the Audio Technica Pro700 (mk1). Plenty of reviews around on that one.
3) I've heard an Ortofon DJ headphone which was apprently a rebadged Ultrasone DJ1. It... wasn't a good experience.
Thanks for the opinions.
I'm a huge fan of the DJ1/HFI 580. However, I have yet to hear the DJ1 PRO, but they look really classy.
I see that you also have the Amperiors. How would they compare in a shootout with the HDJ 2000? I've only had very limited listening time with the Amperiors, but I was fairly impressed with the HD 25-1 II. How different are the 2?
