There is an app on the play store called [ROOT] Beats Audio Installer. It is made by motioncoding, so all the credit and thanks should go to them. What this app does is that it installs the beats audio drivers to any android phone, as long as the phone is rooted. It is advised that one makes a backup of their data (nandroid and titanium will suffice), because once you install this app and run it to install beats audio, you can't uninstall this. The only thing you can do is factory reset. I have used this app and it worked for me. My music quality is substantially better. YOU DO NOT NEED BEATS HEADPHONES FOR THIS APP TO RUN. I do not know if this app will give you beats audio quality sound if you use youtube, pandora, or spotify. I believe that it shall, if you use headphones to listen to your media, because a "beats audio" notification appears every time you use headphones. I do not know if a lot of people know about this, but I just wanted to share this app, because I believe it is great. The link is: https://play.google.com/store/apps/d...ng.beats&hl=en
There is also a mod that you guys can try. You need to have DSP Manager for this to work, but you can try to see how it works without it. Remember, i am not responsible for anything that happens to your phone. The flashable zip is linked.
If you have any questions, please comment. Remember, thank motioncoding...and you can press the "thanks" button if i have helped you :P
