Equalizer does not work with all music players. Some have equalizers of their own, and others are just not compatible. If you have issues with your music player please contact us. We recommend using Google Play Music, Meridian Mobile, or Omich player.

Installation of Unlock Key:

This is an unlock key and not a stand-alone application, all you need to do is download the key and install it on your device. The first time you open it you will see a dialog and you will then be taken to our Equalizer application, that’s all you need to do!
