This is a rank newbie/ignoramus question, but I cannot find details, specs, or instructions anywhere about the earphones (apparently they have some kind of built-in mic and squeeze button) that came with the N800. On a few Skype posts here on the forum there are scattered references to how to use these earphones, but nada in the box the N800 came in, nor the pdf file user guide for the N800. Can anyone point me to a place where a particularly dense-brained user can learn about how to use these earphones? Or anyone here care to bash out a quick but somewhat comprehensive rundown on N800 stock earphone usage and functionality? Thanks!
