Volume Booster - Sound Booster

Make your phone louder. Volume Booster - Sound Booster (AZ Booster) raises the volume of your speaker, headphones and Bluetooth devices, adds deeper bass and gives you a 10-band equalizer to shape every song. One big knob, one tap, louder sound.

🔊 VOLUME BOOSTER
• Turn the boost knob (0 to 200% on its scale) or tap a quick step to set the level
• Louder music, videos, movies, games, podcasts and audiobooks
• Works as a speaker booster for the phone's loudspeaker and as a headphone volume booster for wired and Bluetooth headphones
• Extra volume when the maximum of your phone is not enough

🎚️ 10-BAND EQUALIZER

🎧 YOUR MUSIC PLAYER, ONE TAP AWAY
