Grrr...don't have any of my reference recordings with me, so it's all classical and ambient today, I.E. just burning in. I don't seem to have one iota of anything remotely vocal. 
 
I must say, they're quite comfy, though, and the all black look (with one sliver of silver going around the earcups) is gorgeous. They isolate pretty well -- I think less than my Leatherhead, and more than my A100Ti.
