If you insist on quality equipment to feed your fragging frenzy, then take note -- it looks as if the folks at Plantronics are about to unveil a serious piece of audio kit for pro gamers. A leaked slideshow has outed the GameCom 780, an over-the-ear headset that features virtual 7.1 surround sound with Dolby Headphone and Pro Logic IIx technology. Each can features a sizable 40mm driver and swivels to lay flat for transportation. Plantronics also touts the reinforced wiring and joints of this setup -- useful for rambunctious LAN parties -- which features a 6.5 foot (2 meter) USB cable. Natur
