I'm looking at buying a pair of NR headsets too and many threads on various forums praise the Bose. My problem is I'm a keen hifi enthusiast and Bose is the very last piece of equipment I'd consider buying as, imho, their stuff is overpriced, overmarketed hype. This is putting me off spending top end for the Bose X's. Does anyone have any comparisons with the "proper" headset manufacturers, Sennheiser, David Clark etc?
