I did a quick research on the website of my preferred hifi magazine. According to this magazine the best noise-cancelling headphones are at the moment:
Sennheiser PXC 450 audio-technica ATH-ANC7 Bose Quiet Comfort 3 (which you already mentioned)
By the way: Grado's iGrado are by far the best headphones available for portable devices according to this and other magazines (not noise-cancelling of course). Worldclass headphones for 80€/49US$. Interesting...
