I know that youve already bought ones but I want to write my opinion on these two headsets for the future customers. Ill start with Hyperx Cloud II because I currently have them and Im 100 percent satisfied with them. They are one of the most comfortable headphones, 7.1 is one of the best in this price range and they are really nice. Sure they have minuses like because you dont have any softwere you have to have dongle to turn on 7.1 or mute microphone but its not a huge minus. Steelseries Arctis arent the worst ones but not good enough. They arent comfortable, 7.1 are pretty good but they arent good for music and videos etc. because they have low bass and sound in general. In contast with Cloud II they are smaller thou.
