About a week ago I received my Sony MDR-CD900ST's, and I've put a good amount of time on them (been hitting them pretty much non-stop, actually), and I've come to the conclusion that they have among the best mids in a headphone I've ever heard. Ever since getting my AKG K271's I considered myself a mid-head, and have been chasing a better and better mid range. I had upgraded to the K601's in an effort to improve that aspect, and was completely satisfied by that move. I've kind of wandered around trying other sound signatures lately, but mid-lust had me wanting a headphone that was more traditional to me.
I had heard of these before, but opinions on them were always mixed, with the only real consensus being that they had a nice mid range. When these popped up on the for sale board, I figured it was my chance to try something new, and, at the same time, not really new. I figured I might get something that had a K601-esque mid range, but in a closed design. What I got, instead, was a vocal range that was miles beyond the K601's. I was floored from the second I put them on, because the vocals were so lush, but not in a veiled or lazy kind of way. I didn't really know why I felt they weren't veiled until a couple days later when I came to the conclusion that they were very, very detailed as well. Not a typical kind of detail where they spike up the upper-mid range, but a very, very natural detail that made the singer sound like they were in the room with me.
Hearing the tiniest little nuances in a singer's voice in a completely natural way has really made me fall in love with the human voice again.
If you find yourself wanting an absolutely gorgeous mid range, these deserve some serious consideration. I don't want to compare them directly to the Sennheiser HD800 or LCD-2's I've heard, but I will say, based on the time I had with those phones, the mids on these could very well be within the same league. They really are just something beautiful.
Has anyone else heard these, and want to share thoughts on them? Gear used with them? Do you feel they improve much when changing amp/source?
