Some people are overly conscientious of people around them, and ask questions like these even though they are already being completely reasonable. It’s a huge jump to assume they must be being an asshole, yelling into their mic etc. Try asking next time: “are you concerned about it because you tend to get excited and loud while chatting? Or is it more just a normal phone-call conversation volume?”

…talking, in your own room, is being an asshole?
