I am looking for some good headphones for playing computer games and watching movies and tv on my PC. I will not be listening to any music unless it is part of the game or movie. Good simulated or true surround sound and bass seem to be the most important for games and moves. A mic is not really import for my gaming as I can just buy a clip-on mic for that. I don't care if I can hear outside noise, but it must block the sound from my game or movie from the people around me. Needs to be less than $100. My sound card is an Audigy 2. How are the Sennheiser HD448 given my requirements above. Any suggestions? What about surround sound headphones with multiple drivers?
