The Corsair HS80 RGB Wireless is controlled through the iCUE software driver. A recent redesign of iCUE made it even more powerful and somewhat easier to use, although the sheer number of options still makes it one of the more challenging peripheral software drivers.
On the Home screen, you'll see two items related to the HS80 RGB Wireless gaming headset: the headset itself and the wireless receiver. If you click on the receiver, you'll be able to update its firmware, initiate pairing, and switch between two modes of operation: PlayStation and Multipoint. PlayStation mode makes the receiver fully compatible with PlayStation 4. Multipoint mode activates the Slipstream Wireless Multipoint technology, which gives you the ability to wirelessly connect multiple wireless devices to a single wireless receiver should you own more than one supported Corsair peripheral.
In the Lighting Effects section of the HS80 RGB Wireless settings are four factory-lighting profiles to choose from: Rainbow, Color Pulse, Color Shift, and Watercolor Spectrum. A "No Effect" preset is also available, along with a few custom profiles (Static Color, Solid, Gradient) and various Lighting Link profiles, which can be used to synchronize the RGB effects between Corsair's gaming peripherals.
The Equalizer menu is where you'll find the microphone controls (gain and sidetone), different system-wide EQ presets, and the option to create your own. The equalizer is a 10-band one with a ±12 dB scale and the option to link the neighboring sliders to make the adjusted frequency response smoother.
The Device Settings menu opens up a window where you can look for firmware updates, adjust the auto-shutoff feature of the headset, disable the microphone LED when the microphone is active, turn the voice notifications on and off, and do a couple of other tweaks.
