1) Your device needs to be rooted!

2) Download this file and unzip it:
http://www.mediafire.com/download/cn...d_FX_v2340.zip

3) Move the correct file (depending on your android version) to your device and install the apk.

4) Once installed, open it and the App will ask you to download a driver, the first effect is enough and it is the one that I use.

5) After everything is ready you can use the App as you would an equalizer.

Tested and working on all my devices, quality of media sound increased GREATLY

Tested on:
