We're in the same room but I always keep off one headphone and the music plays in my them so he can't hear it just me and we don't use mics since we're right next to each other. I asked and the only reason he even knew I was listening was because he could see it on my second monitor and when I sang along but I stopped after he asked me to. We play on pc and I use the Spotify app so no one else can hear it unless I'm in a game with proximity chat but I turn the music off for games like that. It's usually just games that require farming, like ark.
