A free app for Android, by Hundred Five Solutions.

Have you ever listened to your favorite song, music, or speech with your headphones or speakers, only to find that the volume is not loud enough? You know what that is, don’t you? You’re not the only one. This problem is not a new one, but it is a problem that has not been resolved. The reason for this is that the built-in equalizer of Android devices is not good enough. If you want to get the best sound, you have to install a third-party equalizer.

In fact, the best equalizers can be even more than a speaker or a pair of headphones. For example, you can use your Android phone as a Wi-Fi speaker. In that case, you can use the Volume Booster Pro app to make your Android phone sound like a Hi-Fi system. 

The app is simple to use. You can install it in seconds, and it doesn’t require any special configuration. The app comes with a built-in equalizer that allows you to boost the sound.
