From my point of view, the sound quality is just as good as the Razer Kraken Ultimate. I also find the cushions of the Hyper X Cloud Alpha Pro a little more comfortable because they are a little softer.
With the microphone, I had the problem that sounds that are output as microphone input are quietly audible. In various forums I have found that some others have the same problem, which seems to be a software or driver problem that can be fixed.
