At the E3 gaming convention a couple of weeks ago, Turtle Beach announced that select models of its media headsets will be the first products to incorporate DTS Headphone:X, which effectively simulates the sound of up to 11 speakers arrayed around the listener using conventional 2-channel headphones. Turtle Beach headsets are designed primarily for gaming, an application ideally suited for Headphone:X, but they can also be used to listen to movies, the other killer app for this technology. The headsets are scheduled to be available later this year.
I have confirmed with DTS that any device with Headphone:X can accept any multichannel audio stream—as long as the device includes a decoder for that stream—and render it in real time. In that case, the simulated listening environment will be the DTS default. If the audio is pre-encoded in Headphone:X, as it is with the Man of Steel score for the Z+ app (see my thread about that here), content creators can simulate any listening environment they choose.
Turtle Beach is the first company out of the gate with a Headphone:X product, but it will certainly not be the last, and I look forward to finding it in all sorts of audio products in the future.
