Well, for me it depends on what is on TV and what I'm about to play. If there is somthing I liek on TV then I'll play my game without earphones unless I need to use Vent or Teamspeak. But like Counter Strike Source I almost always wear my headphones since I can tell easier when people are sneaking up on me and whatnot. But for say Guild Wars or Company of Heros I stick with my computer speakers.
