It is damn good. you can install an app called Samsung music which is a nice player and it has a terrific equalizer. it has tons of settings. And once you set it like you wish, you can enjoy the sounds in any app(including chrome) using any headphones or the speaker.
I love and enjoy this features. Already finished watching arrow 1, 2 and flash 3 on my J7 prime. Now enjoying Rome and the magician. Once they are finished I will start with game of thrones.also the you tube sounds too good.
