Equalizer Pro is the best tool to enhance the audio quality of your Android device. It provides you with five different audio effects: Equalizer, Bass Booster, Volume Booster, Virtualizer, and Reverb Presets.

The first thing you need to know about equalizer is that it is not just a volume booster. It also offers you the possibility to adjust the sound effect levels so that you get the best sound out of your music and audio files.

The second thing is that the app is really easy to use. Just open it, select your music or audio file, and tap on the equalizer button to start using it. You can adjust the sound effect levels by using the slider.
