In the native Google play music app you have several audio settings, when you go to the settings menu within the app and tap on equalizer.
Btw, Nokia 8 comes with OZO sound. Try to make a viseo recording with the phone and after that put the file to play on a surround sound system. There I do feel the difference.
The Google Music EQ has never worked right on any phone i have owned, i bought Poweramp years ago and never looked back.
