I've seen the video; there's quite a bit of backswing, but he hardly touches him really.
There are also quite a few pastel de natas visible on the table so I'd say this was probably post meal rather than during. It helps to be accurate.
Probably fashion then. You see lots of youngsters wearing the big headphones these days. No doubt listening to your Storm Zees, your Jay Zees and your Cardi Bees and what have you.
