Live poker - headphones, sunglasses, neither?

Seems like sunglasses and headphones are no longer the norm for the majority of poker players.

Do you still wear sunglasses? Why or why not?

Do you still wear headphones? Why or why not and what do you listen to if you do?

I find it interesting how trendy these two accessories became during the poker boom but how relatively non-existent they were pre-boom and in the current era.
