Can't see the OP, and while I understand that the impressions therein may be somewhat... less reliable than those of others who've had the opportunity to listen to more gear (thus allowing them the luxury of making comparative statements across price points and whatnot), it may still prove educational for others, especially if you have other gear to weigh it against. Then again, you do need a certain skillset to evaluate gear with any degree of accuracy, "accuracy" being really vague in this context since hearing is subjective to quite an extent. Also, the HD650 is quite a good pair of cans for the price, especially when you pair it with really nice gear (which I don't have, haha). I'm borrowing a friend's pair soon just so I have a point of reference when reading impressions; they're quite popular on here for a variety of reasons. Only auditioned the TH-900 (Mk 2) for a short while because the treble didn't agree with me. Good soundstage, yeah, and head-rattling bass with a fair bit of detail retrieval, but not quite... excellent.
