Did I make a mistake?

I know people here are probably biased but also hopefully the best people to turn to.

I recently purchased the arctis 7+ and the audio is occasionally distorted and crackly. I've put the dongle in the usb port in the front and I've tried it in the back of my pc. It makes no noticeable difference.

Other than that, I love these headphones. But if I can't figure out how to fix them, I'll just take them back. Any and all help is sincerely appreciated.
