its currently the best performing wireless noise cancelling headphone. If you need noise cancelling its a really good buy. If you don't need noise cancelling or wireless, there are better headphones to buy with your money.

I'm just basing off reviews which majority of them say Sony beats even the Bose QCs at noise canceling. I myself haven't had much opportunity to test either, but both of them are a good choice for noise cancelling based on my brief trying out at shop. If you have the chance, try out both of them before making the jump since neither are cheap.
