I really don’t care if you plug it in or not. I’m more annoyed by the mentality of, “I unplugged it, but someone else can plug it back in. It’s their problem since they don’t bring their own like I do.” These days, it seems like most people are only concerned with themselves.

If 50ish percent (or more) of our guys brought their own headset, then sure, leave it unplugged. Of the guys I fly with, 90-95% use the aircraft headset. It’s WAY more likely that they’ll need to plug it back in, so I personally would plug it back in, especially if I unplugged it. It’s common courtesy. That’s my opinion and I’m done with this conversation. I probably won’t give it another thought... unless I fly after you I guess.
