Newbie, here. Can someone PLEASE give me a final answer on this life-important question? I have a Palm 680. It's older than Methuselah. Not till next May (2011) can I upgrade (for those of you that are wondering...). I have not one but two Palm Stereo 2 in 1 PRO headsets. They make great stereo but the mic does not work. Been to several websites (including Palm). Half says they work with the 680. Half say no. Now, given the age of my 680, it may be possible it is just flat broken. However, the older cheapy Palm headsets work. I ask this because I wear hearing aids and, obviously, they don't work together with the headset. Man, what I wouldn't give for those Palm Pro's to work with the 680. I'd even buy a used but good 680 IF I thought they'd work with the Pro's. Also, if you happen to know a headset that would work with the 680 please let me know. Oh, I've tried the 3.5 to 2.5 conversion jacks. Junk.
