I use this product for CS:GO and have definitely noticed a massive improvement in the things I've been able to hear whilst playing. It's a great all around product with a pretty solid battery life. Functionality wise it only takes a moment to switch on and has pretty solid quality of sound for the receiver also. I did initially have issues with it disconnecting after 5-10 minutes of use but I soon discovered that if you plug the receiver dongle (USB) near ports that utilise USB 3.0 they operate on the same band and cut out, so i just plugged it into a different USB port and had no issues at all. All in all.. great product for browsing the net, listening to music, watching whatever and gaming. Corsair is a really reliable brand and will continue to buy their products.
