Been using a Sennheiser HMEC 250 ANR Headset for the past 12 months. Less than half the price of the Bose and 99% as good. Very good on batteries - just put my second set in after nearly 200 hours use and very very light. Only bad thing I'd have to say is the bag they give you looks great when they come pre packed, but is pointless the second you unravel the leads. My other set is a DC 13.4 and the Sennheiser beats them hands down and isn't that much more expensive.
