Just in case it's of use: I was looking for wireless noise-cancelling headphones (distracting office environment), just before Bose released the QC35s. I ended up getting these Sony ones, and while the noise-cancelling is maybe a tiny bit less effective than with Bose QC25s, it's pretty impressive and I thought music sounded quite a bit better than with the Bose pair. Sony's NZ price is insane ($700, though they Sony salesperson offered to drop to $630 without even being asked), but I managed to pick up a pair for £182 from Amazon UK on sale + £16 shipping which made it a bit better.
