Headphones (noise canceling, even!).

  I was going to say that it was sometimes hard to hold a conversation over the music, but two people with noise-canceling earbuds would definitely up the difficulty. (Or we could just call each other.) ;)

    That could work. But I hate it when the audio is even a little bit out of sync with the video.
