Both. When watching a video or playing something where I don't mind the audio much, I go for speakers. If I am using Skype or playing a game I really want to hear everything in, I use a headset. A Logitech G930 one to be specific, so it has that fake 7.1 surround stuff that actually works very well. I also got a G110 keyboard, so I use two of the G keys on the side to quickly switch between where the sounds comes from. It's pretty sweet.
