Don't let a sleeping family keep you from your new action adventure movie, DTS 5.1 concert, or online video game tournament by setting up these Pioneer wireless surround sound headphones. The SE-DIR800C phones, which connect to any 5.1-channel source--including a DVD player, game console, digital cable box, or satellite receiver--are equipped with Dolby Headphone technology, which produces up to five virtual loudspeakers in your head by directing and reflecting the sound from each channel. The effect is a stunning surround experience, far more dimensional than with typical headphones, and, some say, even better than with a high-performance surround speaker system. The audio is natural sounding and doesn't cause "listener fatigue" as do many other headphones. The phones also work with a variety of surround formats, including Dolby Digital, DTS, and Dolby Surround.
