Arctis 7 was truly the best headset, I have three pairs at this point. None of them broken - all were purchased because the headset was so good I wanted one for the office and for my wife.
However, Steelseries seems deadset on making worse versions of the Arctis with every iteration. The 9 was altogether disappointing and they are really trying to force all the features like the chat mix into Sonar software instead. Really disappointing.
