I like using the included earbud headset that has the built-in microphone, but after a while earbuds REALLY hurt my ears. I mean they just feel like trying to squeeze a St. Bernard in through the cat door (thanks Mr. Foxworthy). But I still love the excellent call quality of having earphones on instead of a phone earpiece at one ear. I saw a $20 microphone/iPhone audio adapter (Monster iSoniTalk) on the Apple Store Web site. I like these Sony over-the-ear headphones I have, so this seems like it would be an excellent idea (although an extremely long cord). Anybody got any suggestions or products that I don't know about?
