Volume Booster: Sound & Bass

Is your phone too quiet? Make it louder in one turn of the knob.

Volume Booster raises the sound of your phone above the normal maximum, then lets you shape it with a 5-band equalizer, a bass booster and 3D surround sound. It works on music, videos, movies, games, podcasts and calls in other apps, through the speaker, wired headphones and Bluetooth.

PRIVACY
Volume Booster uses Android's own audio effects. It never records, stores or sends your audio.

Hearing safety: listening at a high volume for a long time can damage your hearing and small speakers. Raise the boost step by step. How much louder the sound gets depends on your phone, speaker and the app you play.
