Your phone can be much louder than you think, it just needs the right app to help turn your favorite songs all the way up. 

If you're trying to get the most out of your phone's speakers, want more bass, or you just want to improve the sound quality of your phone calls, we've got the right speaker booster app for you. 

Note: Regardless of which speaker app you decide to use, you run the risk of damaging your phone's speakers, your headphones, or your own hearing if you set the volume too high for too long. If you hear distortions in the audio, that's an indicator the volume is too high. Use these speaker booster apps carefully.

A screenshot of the Volume Booster by GOODEV app begin used with the Android version of the Spotify streaming music app. The top part of the screenshot shows the Spotify player while it plays a song and the bottom half of the screenshot shows the Volume Booster app in use as the song plays.
It doesn't take much to create a super loud, immersive audio experience with Volume Booster.

The Volume Booster app by GOODEV is the most versatile loudspeakers app for Android without being a music player. The app can boost the volume of either your phone's speakers or your headphones. While it's not intended to increase the call volume on your phone, it works to boost the sound while playing music, audiobooks, or movies on your phone. 

Volume Booster is a powerful volume booster app. So powerful, in fact, the app comes with a warning from the app developer stating that using the booster at high volumes for long periods of time may damage your speakers or your own hearing. 

Volume Booster by GOODEV is free for ​Android devices. 

What We Like:

  • The download size is very small at just 2.42 MB. 
  • A little boost goes a long way: Even​ a 16 percent volume boost is enough to create an immersive audio experience.  ​

What We Don't Like:

  • It's very easy to accidentally turn the volume up too high. The slide-style control could very easily slide across to the higher end of the volume spectrum quickly.

Volume Booster Pro By Music Hero: Best Overall Phone Volume Booster

A screenshot of the Volume Booster Pro app in use on an Android phone. The screen shows four volume knobs set to the Normal preset. The four volume knobs are labeled as System, Voice, Music and Alarm.
Set your phone's audio to one of three presets, then further customize each kind of audio.

Volume Booster Pro is a very simple volume control and booster app for Android phones. The app allows you to not only increase the loudness of music played on your phone, but increase the volume for phone calls, alarms and other phone system sounds, such as ringtones and notifications.  

Available on Android devices, Volume Booster Pro is free to download and use. 

What We Like:

  • Simple, easy-to-use interface with volume knobs for each kind of phone sound, like system, voice, music, and alarm. 
  • Three volume boost presets (Muted, Normal, and Max) to give you an idea of the kind of range this app has. Even set at Normal the volume gets pretty loud, and you can still move the knobs within each preset to hit the percentages that work best for you. 25 percent used on headphones seemed to work the best. 

What We Don't Like:

  • While the presets are customizable, the knobs can't move beyond certain percentage ranges. For example, on Max, the lowest it will go is 86 percent.

There are also options to change the vocal and balance levels as well different acoustic styles to choose from. You can also just hit the Reset button to set everything back to normal.

Bass Booster and EQ Power does exactly as its name implies; it boosts the bass of songs played on your Android phone. That's not all it's capable of doing; Bass Booster and EQ Power also offers reverb presets, the ability to create ringtones out of your songs, and a sleep timer. 

Available on Android devices, Bass Booster and EQ Power is free to download and use. 

What We Like:

  • The Power Bass feature is indeed powerful and best without headphones. With headphones, you can just use the Bass knob and turn up the volume. 

What We Don't Like:

  • The volume control under the FX menu isn't very responsive and sometimes gets stuck on certain levels.
