The headphones do not matter, USB headphones were picked as examples because they're 'sound cards' usually. You could substitute 'moving from HDMI output to your speakers' or something. It's just about the ability of migrating running audio between devices, something I'm regularly doing. Sound at the same time: Happens regularly for me. I'm listening to music and some IM client runs. I could mute that client (in the client itself) or .. reduce the volume of that one application (in PA). NoScript and RequestPolicy were too much of a hassle to me in the past tbh. I regularly end up with a braindead/moronic website playing some random video. Muting flash while I look for the offending tab makes me a much saner person.
