Yes
1/ open enhancement app, and tick DSEE HX or whatever options, don't matter.
2/ go to setting, then apps
3/ swipe left to the end for the tab "all"
4/ scroll down and look for "sound enhancement" app. Select it, disable
5/ confirm
***if you are listening while disabling the app*** turn your volume down....the sound will be 2-3x louder at the same volume level !! Don't blow your ears drums
I believe I get the best juices and quality from ZX2. Now this is true audio quality, and non of the color, software enhancement craps....won't even be possible to EQ, but I doubt you need it if "true, accuracy, realistic, quality" music is what you are chasing for. Assuming why you buy this ZX2 in the first place
1/ use TRRS connection whenever possible
2/ have to disable "sound enhancement" apps
