The only thing that put me off Bose was that primarily they are a marketing company rather than a manufacturer. Almost everything else they produce is over-hyped and over marketed (Sunday supplements anyone?).
On the other hand Sennheiser are a pucka headphone manufacturer (DC's too vice like for me also). I recently bought a couple of pairs of 450's from the States. Worked out at £322 each set with the VAT paid. They have excellent passive noise reduction and the electronic NR is top notch as well.
Might be worth looking at them also. The 460's are identical except they have option to plug in mobile phone and iPod, something I'd never use, so save and get the 450's.
