Find someone who has a good set of cans and listen to them side by side with any Bose headphones and you'll know right away.
I had a pair of Bose QC2 that I used and loved for years. Once I heard the Ety ER-4Ps, I've not used the Bose again. I then got an amp and a pair of Sennheisers and the world is a different place.
Bose is a marketing machine, and their gear does not compare with the "real" players in the market. As an example, the Bose QC2 are $299. For that price you can get a pair of Sennheisser HD-650 which are considered to be the best headphones under $1000 by a lot of people. You could argue that you're paying for active noise cancellation in the QC2, but for less than $200 you can get passive NC that works better and sounds better than the Bose.
If you want headphones that look cool over headphones that sound amazing, you're in the wrong place and you will get flamed constantly. If you open your mind to the idea of killer sound over looks, you'll find that Bose has led you down a dark path.
Seriously - the people here can show you cans that will sound 10x as good as any bose for 1/2 the price (or more!).
