Creative X-Fi SoundBlaster PCI-Express SB104 70SB104000000 Internal Sound Card (Retail)

Surround sound from your stereo music and movies? Yes!
Expand your stereo music and movies into surround sound. Voices are centered in front of you. Ambient sound appears all around you... just like a live performance. Listen on a pair of desktop speakers or a full 5.1 speaker system.

Hear headphone surround that sounds like multichannel speakers
Slip on your headphones and X-Fi technology moves the sound away from your ears and into the space around you. You'll be surrounded by nine virtual speakers and feel like you're sitting with your favorite band or in the best seat in the movie theater. Games sound better too with positional audio that's so accurate you can locate enemies by sound.

Experience cinematic surround sound from DVD movies
Watch your DVDs in cinematic surround sound with PowerDVD software featuring DTS™ and Dolby Digital® -EX decoding (free download with purchase).
