Add the Sound Blaster X-Fi Xtreme Audio sound card to your PC and turn your downloaded music into your own personal concert. Watch DVDs or downloaded videos with full cinematic surround sound. Restore the details and vibrance your music and movies lost during compression. X-Fi technology intelligently enhances the highs and lows so you'll hear it all-crisp cymbal crashes, wailing guitar solos, screeching tires and booming explosions. 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. Put on your headphones and X-Fi technology moves the sound away from your ears into the space around you. You'll feel like you're sitting in with your favorite band or in the best seat at the movie theater.
