I have a mono plantronics ear/mic boom headset with a 2.5mm jack which was designed for a mobile phone. I happened to have an old pair of bust headphones with a stereo 3.5mm plug on it, so I snipped off the lead about 4 inches long, and soldered on a 2.5mm stereo socket.

The connections are 1:1, tip to tip, middle to middle, back/case to back case. Use a multimeter if in doubt as to which is middle which is tip, case or back is generally obvious.

It works pretty well with the kphone/sip-phone and voice recorder application, and with a bluetooth network adaptor networked to my desk PC running SuSElinux9.2, I've used it with our VOIP system at work (had to "acquire" my extension's password using a dubious bit of network sniffing with ethereal, but that's for a different forum!).

I'm thinking of making a little switch box so that I can use a stereo headset, with a switch to change it to a mono headset plus microphone.

I have wondered if I need a three-way 3.5mm plug - does the Zaurus's connector output stereo sound and simultaneusly have microphone input?

As far as i know, you just need the switch between the second speaker and the mike... i think the applications change it to input / output.
