Add me to the list of people who prefer Audio-Technica ATH-M50. For the money there is no better value for a set of closed cans. For open/semi-open I have a set of AKG K 240 MK II that let in enough ambient sound that I don't feel isolated when I don't want to be. For my teenaged son, I buy the Senn HD 201 for $15 on sale because he's so hard on them.
