Weird echo sounds coming from my mic on Discord (Hyperx Quadcast)

So today I finally received my Hyperx Quadcast and I've been very happy with it so far. It was all fine and dandy till one of my friends started streaming on Discord and when I turn on his stream, there is a weird echo sound coming from my microphone when I talk. It doesn't happen when I don't watch the stream. Turning on Discord noise suppression seemed to fix it but I have no idea why this is happening. I didn't have any issues like this with my headset microphone. I would prefer not having voice suppression since I've had problems with it in the past where it's cutting my words off. Any suggestions? :/

Update: I've found out that turning off noise reduction also fixes the problem. That was the problem I think. Weird.
