I got the Audio Technica ATH-M50s headphones with a Fiio E11 amp. I don't think the amp makes a huge difference, but it does make some difference. For a lot of my research, I read reviews and opinions on head-fi.org and its forums. I picked the ATH-M50s because they seemed to have comparable sound quality of headphones in the ~$300-$400 range, but were reasonably priced. With the amp, they also have a good amount of bass. With and without the amp, they sound very clear, especially high up. This is the first "good" set of headphones that I have owned, so my ability to compare is limited, but I think they sound a lot better than the Bose noise-cancelling ones, and those sound pretty good to me.
