DTS offered one of the show's more interesting audio demos with DTS Headphone:X. The audience were given Sennheiser headphones selling for roughly $100. With headphones off, we heard an 11.1 channel check with front, front height, center, side surround, back surround, and back surround height channels (not including sub). Then the channel check was repeated with headphones on. It sounded precisely the same and the sound still seemed to be coming with the speakers. Finally we were invited to hear the channel check while removing and replacing the headphones. At this point it became clear that the sound was coming only from the headphones. The steering was impressive, with the side, back, and height channels occupying their places in the soundfield with the same confidence as the front channels. DTS also did an A/B demo of the Vizio VHT215 2.1-channel soundbar with various technologies acquired along with SRS Labs. Even amid the noise of the show floor, it was clear that what is now called DTS TruSurround (formerly SRS TruSurround) was lifting the soundstage clear of the bar's physical limits. Just a little, but enough to be noticeable.
