+1 Sound is really the most difficult thing to adjust. I wouldn't be able to do it alone as any feed back pollute the original and headphones would cut off your normal voice feeback
I hate when I take a long time as viewer to explain the model how to adjust it better and give her the feeback she has not... then entering a day after in her room with a maximum distorsed shouting music all in trebbles xD
wait, how are you telling them how adjust? through obs, logitech, or device settings on her desktop? i'm only asking because obs and logitech sometimes don't save settings. to get my mic settings to save, i have to adjust through my desktop.
or do they factory reset everytime they turn off their computer
