I went from my Shure e2C's to some cheapy Philips earbuds w/ the wraps simply because they are so much more comfy to wear on the treadmill and in the gym and don't fall out. The sound quality is not quite as nice... but barely noticable (to me). $6 compared to $100 - its a sure winnar. Got them at target.
Too bad Shure doesn't make the wraps.
