Just posting this in case anyone else has had this issue, I've googled around and saw no solutions, but I did notice someone else having the same problem only with the G35 headset.
If your desktop audio sounds like it's in a tunnel and/or very echo-ey stop using your headphones as OBS's desktop audio source. Something weird is happening where the logitech software is passing the processed sound mix into OBS. I've tested this and found this problem is completely resolved when switching to my speakers or any other non-Logitech audio device. I have fiddled around with all of the settings in the logitech gaming software and could not come up with a solution that would allow the use of the logitech headphones without the stream audio issues. The only workaround I have come up with is to use your stereo mix and select the G930s as the "listen to this device" option.
Sorry if this is a jumbled mess, this audio issue was frustrating the heck out of me until I narrowed down the problem. If anyone has any solutions/suggestions that are better than the ones I've presented, I'm all ears.
