You've only got one set of ears, spares for those are really hard to obtain. I would advise you to find a shop or club where you can try some headsets before making a decision. I use DCs with ANR but would consider getting a Bose headset when this one gives up the ghost (don't hold your breath). I've you're spending a lot of time in cockpits, invest in ANR, it really helps. And Bose does have a lot of experience in this field...
