the hyperx cloud (any really) is a great headset, however going with an audiophile grade pair of headphones and a mod mic will have much better quality for both mic and audio. 7.1 is pretty much BS marketing companies do to bump the price. True 7.1 is achieved by multiple drivers for each ear, most (If not all) gaming headsets only have one driver per ear.
Here's a link to the antlion mod mic 4.0 https://www.amazon.com/Antlion-Audio-ModMic-Attachable-Microphone/dp/B00T6XUL8S
I hope this helps.
