Not one, but two Sennheiser headphones! The staff likes to equip themselves in style . I can't help but add a third Sennheiser to the list for those with normal budget constraints - the Sennheiser HD 280 PRO. These headphones can be had for under $100 (not the $500 price range of the ones in the article) and you still get great audio quality with 8Hz-25kHz frequency response. They only offer passive noise canceling, but I find that perfectly adequate for my needs. (I'm using a pair of HD 280 PRO headphones as I write this.)
If you want active noise cancellation but can live without the talk through feature, try looking for the PXC 350s. They can be had for $200-$250 and have a longer battery life. For some reason, NewEgg doesn't carry them.
Google says that IncrediCell is the best bet for a low price on them:
