"Simply plug the MX100's into your iPod and mobile phone at the same time, set your mobile phone to vibrate, and turn up the tunes! If you feel your mobile phone vibrate, flick the switch from music to phone then answer your phone without taking off your headphones! When you're on the phone, the AcuSpeak microphone technology delivers clear, crisp conversations. The MX100-s works with your iPod and most headset-ready mobile phones, including Motorola, LG, Audiovox, and Kyocera. Plantronics also makes available - free of charge - adapters for the most popular Nokia and Sony Ericsson mobile phone."

Of course until one of the iPod enthusiast sites, such as iPodlounge or iPoditdue.com, reviews the sound quality of the MX100's vs. the current recommended crop of iPod compatible headphones, like the Shure, Etymotic or Sony Fontopia family of earbuds, it will be tough to say whether Plantronics solution will be acceptable to the more discerning ears out there. But I think its pretty safe to say if you are the kind of user who is more than happy with the Apple supplied earbuds that came with your iPod, and are a heavy cell phone user, the MX100's may just be the product for you.
