The Cougar Immersa Pro comes with the so-called Cougar UIX System, a fairly simple driver that offers several audio profiles as well as microphone and RGB lighting controls.
On the main screen, you'll be able to choose between various audio profiles, or adjust the system-wide equalizer to your own liking. Here's where you can add a bit more bass if you find it lacking (which you most likely won't). User-generated equalizer settings can be saved to a custom profile, and you can create as many of those as you like. There are two microphone controls; volume (gain) and monitoring. Microphone monitoring enables you to hear whatever is picked up by the microphone through the headphones, and the monitoring slider is used to determine the volume of what you'll hear. The purpose of this is to prevent you from sounding nasal or talking too loud, two common side effects of using a closed-back headset whose passive noise isolation prevents you from hearing your own voice while talking. The microphone-monitoring is there to help with that, and it's a great feature I enjoy using. I found it best left at around 50%, but you're free to play with the slider to figure out what suits you best. It should be noted that the sound picked up by the microphone gets reproduced in the headphones with no perceivable delay. That makes the microphone-monitoring function of the Immersa Pro perfectly usable.
We can pick the color of the two rings on the ear cups in the "Lighting Control" section of the Cougar UIX System. It's a full-RGB system, so you can go with pretty much any color you prefer, or several if you select the Swift X2, Swift X5, or Swift X7 effect, which makes the colors shift from one to the other; two, five or seven of them, to be exact. The speed of each effect is also selectable via a slider. You can, of course, turn the effects off completely if that's what you desire.
