For anyone interested, DTS Headphone X is now free to try on iOS and Android phones via an app. It is tied to the release of the Man of Steel soundtrack. You can also buy a CD with a code to get the soundtrack within the app, but sound files outside the app are not available, it seems.
I have tried it and notice that the effect is pronounced but it also changes the frequency response of the content quite a bit. For voice it is fine, but music is less enjoyable as a result. I also have been listening to headphones more than loudspeakers lately, so maybe my brain is more tuned to headphone listening as a result.
