I have the MDR-1000x as well and can't recommend them enough. I was already quite happy with Bose's noise reduction, but the sound quality of the 1000x is so good it seems you're not making tradeoffs. It also has a special noise cancelling optimisation function where it apparently adjusts to the shape of your head, whether you're wearing glasses, etc. I can't honestly say whether this actually works or it's mere placebo. The only downside is that sometimes I try to pause a song and it forwards to the next one instead, so I'm either an idiot or the touch sensitive controls could be improved.
