My old pair of Denon AH-C560R inears have given up on me, so I was thinking about getting a proper pair of sport in-ears this time. I'm currently looking at the Sennheiser CX 685, so I was wondering if someone had any experience with them, and what alternatives there are in roughly the same price range (up $80 is ok). I would like them to have good impact with the base, but without sacrificing to much of the other soundstages.
 
Thanks for suggestions!
