LifeVibes MusicFX control panel will unlock the audio effects in Android. This app unlock the audio effects like rich 3D experience on headphones(stereo widening and reverb), bass boost and equalizer. Just install the app and you’ll find the control panel under the menu item in Android Music Player.
You can customize the settings of MusicFX by setting Equalizer, Bass boost for headphones and 3D effects for headphones. Remember Last two option will activate only if you plugged in headphone.
