Are you playing on PS4, Mavilu?
If you are, you should be able to connect some headphones/earbuds straight to the controller.
Uncharted: The Lost Legacy - Great game if you like Uncharted and/or Chloe Frazer (check and check). Doesn't really feel like DLC since it's on its own disc and doesn't even require U4 to play. It's a decent sized jaunt for the price.
