Just got back from a trip to China and Japan. I used the Shures and my hubby used the Bose QC2's. He was a bit upset when he saw me sleeping comfortably with my Shure's playing music from my iPod while he tried to find a comfortable position to get a nap in with his headphones (the flight was rather noisy in Business class and there was no way to sleep without some kind of noise blocking headphones/earbuds). Now I'm glad that I didn't buy 2 sets of QC2's. But it looks like the QC2's will be going on Ebay....because now hubby wants the Shures.
