Shure's MPA-3c converts headphones to headsets
Shure -- a company with a long tradition of both excellent headphones and questionable accessories -- is introducing a new iPhone-targeted add-on into its stable called the MPA-3c. The gist of this adapter is that you can plug your high-fidelity Shure earphones into it and magically turn them into a headset for use with a cellphone (oh, and they claim that it delivers "rock star" quality audio). Essentially, $39.99 will get you a microphone and a send/end button that matches your iPhone.
