Don't let a sleeping family keep you from your new action adventure movie Dolby 5.1 concert or your on-line video game tournament. Go ahead and experience all the 3 dimensional sound your heart desires! Dolby HeadphoneTM technology produces up to five virtual loudspeakers in a virtual room via conventional stereo headphones creating a unique sum of direct and reflected sound from each channel of 5.1 audio. As a result the listening sensation is much more natural with sounds appearing to be outside of your head just like a conventional 5.1 speaker system would sound.
