In fact several things have changed in NC headphones since, well, mid 2007:
Panasonic RP-HC500
Sennheiser PXC-450
Sony MDR-NC500D - the first digital NC headphones apparently
My favorite for sound quality are the Audio Technica ATH-ACN7 set while for plain old NC it is the (now discontinued) Logitech NC headphones (I put this set on while standing next to a 2 stroke lawn mower and all I could hear was a slight rumble - outstanding!)
