I just picked up my copy of 'Pearl Harbor' tonight, and it has this feature on it called 'Dolby Headphone Track', what this does is simulate a full 5.1 soundfield within the two channels of any pair of conventional headphones! I watched the entire horrifying attack sequence with it, and it is so damn cool! It really works, when actors speak, it sounds like their voices are coming from an invisible and seamless soundstage placed directly in front of you! Bullets whizz from over here, bombs explode over their, it simply kicks ass! Other studios take note, please consider this feature for future releases, it will make late night viewing MUCH less painful!
