Question / Help annoying echo effect throughout my recorded gameplay and streams

[Grappler_senpai]

for some reason,whenever I stream or record myself,there's this annoying echo effect that I can't get rid of,
I don't know if it's my PC or something like that,I've even used NVENC codec and x264 codec I've tampered with my headphones,the mic volume,the desktop output volume,EVERYTHING!
I don't really know what I should do....
whenever someone speaks,it's this annoying echo that annoys me and everyone,
I also have very slow internet so I have very little time to tamper with anything and I'm dissapointed to see that I wait 9 hours to upload 20 minutes just for it to have that echo effect on the audio....
btw I'm recording on my monitor through HDMI.....I don't know if this affects anything...

Do you have surround sound headphones by any chance?

I don't know if ONIKUMA headphones are surround sound,
and my windows is up to date and I still can't switch it off
