While I love the sound quality and overall comfort of my X10's, they seem very, very fragile. I only listen to them in an office environment, so I'm not too worried about damaging them. When not in use I store them very carefully with my iPod in the supplied Klipsch case. There is no way I'd use these phones at the gym, outdoors, etc. I know that everyone rips on the Bose TriPort headphones, but I really like the cable that comes with them - not too thick, not too thin, and not coated in fabric. I might actually use them more if I can fit my Klipsch gels on them (for instances when I'm not listening at my office). I know that people don't like the Shure cords either, but with my limited time with my SE210's I found the cord to be quite nice (again, for indoor office use only).
