Sorry, just saw the question,
Yes, Logitech devices are extremely programmable, in fact it comes pre programmed that the top button is for turning the mic on and off, second button turns on/off surround sound and 3rd is to cycle through sound effects. once you download the Logitech software you can program any of the buttons to do about anything you want, hotkeys,recordable keystroke macros they even have hot keys for Ventrilo and other programs. I love this set. Lights are programmable too in many different set ups again through the Logitech soft ware. Hope this helps.
