Just bought nari ultimate. has echo that I can not get to stop.

I just bought these headphones, and everything worked fine until I discorded a buddy to play a game. From the very beginning, he said there was echo. He could hear himself and my computers audio. I have tried every single solution online I could find. Discords echo cancellation doesn't work. Nor does changing any sound options, or quality. The only thing that does make it stop is disabling the mic itself in the sound settings. Other than that, it is this excessive echo that won't go away and is driving me nuts at this point. Every pair of expensive headphones I buy always has some issue. No idea what to do at this point. I'm really hoping someone has a solution. Or at least news on a software update coming in the works. AS it seems others have this same issue to.
