I'll have to check those out, thank you. Gotta admit I've only personally tried qc20 and qc25, but most reviews of new NC headphones that I've read on The Verge still hold Bose as the standard-bearer of high quality NC. Everyone else, even the very expensive stuff from Sony, seems to come very close but not surpassing the bose NC stuff.

edit: maybe it's a little self-rationalization for paying so much for the QCs. I'll have to give those Bluedio's chance before shelling out anymore to Bose
