Open in StoreTurn up everything you play. Speaker Booster Full Pro is a simple volume booster that raises your phone or tablet's loudness beyond the standard maximum, so music, videos, games and calls come through louder and clearer.
Set your normal volume, then move the boost slider until it sounds right. That is all it takes.
Boost every sound on your phone
The sound booster works on top of whatever you are playing:
- Music and MP3: make your favorite songs louder in any music player.
- Videos and movies: catch every line of dialogue without straining to hear.
- Games: hear voices, footsteps and effects clearly, even outdoors.
- Audiobooks and podcasts: lift quiet narration to a comfortable level.
- Radio and streaming: give quiet stations and streams extra power.
- Calls, alarms and notifications: stop missing what matters.
Louder on every device
- Phone and tablet speaker: get extra loudness from the built-in speaker.
- Wired headphones and earbuds: boost quiet recordings to a comfortable level.
- Bluetooth speakers and headsets: add extra gain when your wireless audio is too quiet.
Simple controls, sensible limits
- Two sliders, one screen: adjust the system volume and the extra boost separately.
- Soft Boost: a gentler mode for smoother sound at high gain.
- Maximum boost cap: limit the boost between 10% and 100% in the settings to protect your hearing and your speaker.
- Status notification: see at a glance that the booster is running and reopen the app with one tap.
- Remembers your levels: your volume and boost settings are restored automatically.
Light and private
- Small app that installs in seconds.
- No account and no sign-up.
- Available in 75 languages.
Listen safely
Playing very loud audio for a long time can damage your hearing and may strain small speakers. Increase the boost step by step, use the maximum boost cap, and give your ears regular breaks. You use the extra gain at your own risk; we are not responsible for damage to your hearing or your device.
About the notification icon
When the boost is set to zero, the booster is off. The notification icon is simply a shortcut that makes it easy to reopen the app. If you would rather not see the icon while the booster is off, open the app's settings and choose to show the notification only while the app is active.
