As an audiophile, just saying, apple earbuds have the worst sound quality I've ever heard in my life and you could have just gotten use to the really bad and weird sounding nature of it
Sure music on cloud alpha might not be balanced as it's more bassy and the soundstage might not be as wide
But it.may just be your settings in the hyperx app and your EQ things
If you're using windows 10, u have to go to settings to change your mic input to cloud alpha mic for it to work
