Flipping the surround sound switch to on radically changes how the G35 gaming headset processes audio, acting as an all-in-one toggle for the Dolby Headphone and Dolby Pro Logic II effects. With it on, stereo music is up-mixed into a 5.1 surround sound field with subtle reverberations that trick my ears into thinking that I'm listening to music in an open environment. Up on the review block today I?ve got a gaming headset from Zowie Gear called the Hammer. The Hammer is made for gaming specifically, and for gaming it works well, but if you?re looking for a headset that you can use for music and movies as well you might want to look elsewhere. They've recently released a gaming headset called the Keid 20 and that's what I've got of review for you today.
