jquero ... interesting solution, although I'm not sure I could wear it for 8 hours at a time, I'd think the holster would break.
Going with an over-the-head style headset would probably be a good option, but it's not quite as unobtrusive as what management would like us to have. (They do supply earbud style earpieces, but I've found that I can't wear them, they hurt too much)
