I have the DN-2000Js from the first drop and I've been very happy with them. I agree with reviewers over on Head-Fi that the treble was initially way too harsh for me but I also feel these things need significant burn in to sound their best (some have said 100+ hours). I now have about 36 hours worth of pushing pink noise through them overnight while I sleep and they are much less harsh on the high end. I'm looking forward to re-evaluating them again once I have the Comply tips (my preferred) in.
