The home menu for the G633 features a graphic of the headset with glowing G-Keys. Clicking those keys brings up the G-Key assignment menu which can also be accessed from the bottom row along with the other settings.
On the G-Keys setting menu, there is a list of commands to the left of the headset graphic that can be modified or assigned to a G-Key.
The breathing effect lighting effect causes either the logo light zone or the side light zones or both to pulse on and off at a certain rate in the settings.The color cycle lighting effect causes the lighting zone to change color continuously in a set order.
A volume level and equalizer menu controls the system volumes of the headphones and microphones as well as providing a simple equalizer and an advanced equalizer. To the left is a list of equalizer presets and custom sets.
The G633 features 7.1 virtual surround sound implementations from Dolby and DTS. During our listening, there wasn’t any substantial difference in positional audio so it is probable that the virtual surround is upmixing the stereo input to simulate the sound of a spacious room with speakers.
DTSL Headphone:X has a few settings selectable in the drop down menus. There are three room presets – DTS 7.1, First Person Shooter, and Logitech Signature Studio – and three stereo modes – Super Stereo Front and Super Stereo Wide.
