Volume Booster・Bass Equalizer

Volume Booster・Bass Equalizer turns your iPhone or iPad into a comprehensive audio enhancer. It works with all audio sources—from your library to streaming services—letting you boost bass and overall loudness up to 1000%. The built-in equalizer offers more than 20 presets (Pop, Rock, Jazz, Hip-Hop, and more) and a virtual surround effect for a richer listening experience.

Import audio from iTunes, iCloud Drive, and cloud services, create playlists, and enjoy offline playback. The app includes full playback controls, AirPlay support, and safety cautions to protect hearing; adjust bass and volume to taste and begin listening with louder, clearer sound.
