Paired flawlessly with my Chocolate.  Have used it almost 30 feet away from the phone without losing connection!  The earbud covers - you get two different ones (one set of one, two of the other.)  The traditional, round, style have better sound but fill with sweat when working out. Literally fill - have to drain them every 15 minutes or so. The open style does not have this problem, but has poorer sound quality and lets in more ambient noise.
