We recently updated the DPS engine and the profiles available in jetAudio’s Music Player app. As it stands now, it has more functionality than the DPS 2.0 freeware product. This is by design since, as an in-app purchase, it is a paid product. Some features, like the EQ, are left out since jetAudio includes that functionality in the base app. Another feature, stereo controls, are called “Bongiovi DPS Headphone Enhancement” and are somewhat simplified in the jetAudio app.
