I use them a lot. Like all the time - im a student in highschool (only a few more weeks!) so im constantly taking them in and out of my little pouch for my Sansa and UM3X.
When I got them previously owned there was some where and loose fitting of the outer plastic. That post was not me bashing the headphones build quality - but acknowledging how easy they are to fix and stuff.
Eventually ill get sick of messing with this current shell and try something new probably using the existing drivers.
