Query: good sound, interesting clip design

I bought these headphones because of all the hype on the forums and the raving reviews. They ARE pretty nice.ProsGood soundTweak-able clips can result in great fitConsClips can fall off with just a little forceFit takes a little getting used toClips & fitThese clips are on a flexible joint to fit different ears. They're also bendable and so you can tweak them until they fit your ears well (never perfect). But many times while I was tweaking my clip (the left one especially) it falls off. They're easy to put back on though.
