I'm another pin-head (must be a girl thing) and I have found the BoseX to be great (if you really want to spend that sort of money).
Currently I'm wearing a Telex Echelon which is small, light, comfortable and good value (it's also not green).
Dave Clark do a "youth" option headset for heads that measure less than 21" around.
I also have my eye on a purple Softcomm ANR headset in youth size!
