If you're using headphones via your laptop, you don't need to turn off the volume if you are using the TV. However, if you play games on the same laptop. You've got to lower the volume of music/games/whatever in the laptop is far below the volume of subs, because decreasing the effect. Why don't you use headphones through another device?, for example, you could use headphones via the iPod when playing games on the laptop. It would be fine (but not fun). The best solution, you can use the track ultrasonic via speaker, and you'll be fine (and more enjoyable).
