For those of you that HATE the fit/feel of Apple's iPhone earbuds but love the play/pause/answer button, there is a cheap and effective solution. Previously released for the stock iPod earbuds, Comply's Whoomps attach to the stock buds and convert them to in-ear buds.
I've tried the Griffin Ear Jams, but they distort the quality of the sound with too much bass. Everything sounded muddy to me. The Comply Whoomps get around this by venting the sound through pin-holes. The combination of these vents, Comply's ear foams (which are not replaceable), and the angle at which they attach to Apple's buds make these a clear winner.
Last shameless plug: I'll have a longer review with pictures on my blog,
