Almost a decade on the same 850's I bought as a new hire. Plenty quiet and every few years it's cheap to replace the ear seal/pad things and the mic muff thingy. Beyond that there are lightweight, easy on the ear comfort if you wear sunglasses, and are in a small package which is always helpful. O- and no batteries to deal with. When I started I sold my Bose from GA flying and got the 850's. I love Bose headsets and really all the Bose audio stuff (use Bose in the house) but for the CRJ it's a waste of space and money.
