Just the other day I was listening to multi-channel DTS bitstream tracks from a Harman Kardon 7.1 surround demo CD. The effect is stunning through a proper system, it was the first time I 've truly heard the acoustics of a concert hall replicated in my living room. If the same quality can be achieved in headphones it would represent a significant leap forward for music listeners and for movie watchers alike.

'Although DTS clearly has their eye on this being a mobile-geared technology - ideal for laptops, smartphones, and tablets - the late night home viewing implications cannot and should not be overlooked. With Headphone:X built into an A/V receiver and a pair of wireless headphones, one could conceivably experience a stirring late night movie without compromising the surround experience, and more importantly, without waking the kids and neighbors.'
