Yes, ….and there's the problem. Just flew with a guy that did that. Annoying in the extreme. Every time I tried to talk to him, "Huh?"

I had to tell him to either take it off, and listen up the first time. This was the 777 BTW, not really any noise to speak of anyway.

And for god's sake, if you do use your own head set, put the company one back when you are done, please!!
