So what's wrong with the Bose head phones? I am well aware of their home audio history and BS, and generally dislike....but I thought their headphones and car audio was highly regarded??? No?

I wanted to get a pair for travelling, air travel mostly. The Bose noise cancellation headphones looked like the ones to get. A friend of mine has a pair, and I thought they sounded pretty good, they are comfortable and they have a nifty travel case. Should I be looking at different head phones for traveling?
