Extra Volume Booster Equalizer is a free audio utility for mobile by Magic Mobile Studio. It is an audio equalizer app that helps users adjust the sound from their devices through equalization. With it, they can change bass, mids, and treble frequencies to suit their liking.

Similar to Music Equalizer or Bass Booster Equalizer, Extra Volume Booster Equalizer makes it easy for anyone to make system-wide changes to the audio coming out of their devices. It comes with a built-in one-tap volume booster feature to increase the output of sound for music, videos, and even games.

Your sound

Smartphones and tablets nowadays serve as portable entertainment devices for consuming all types of content, be it videos, music, or games. Given their large and vibrant screens, it's no wonder why that is the case. One area where things are not as impressive is sound across various aspects—output, quality, and signature. This is where apps like Extra Volume Booster Equalizer can help.

Put simply, this app is a system-wide equalizer app that doubles as a volume booster. On one hand, you can use it to adjust bass, mids, and treble frequency responses to achieve a specific sound signature you want, either manually or by using the built-in presets. Any changes you make will apply to everything, from your device's speaker to your headphones, and even wireless earbuds.

On the other hand, the volume booster function can increase output from 100 to 200 percent in increments of 25. There's even a virtualizer knob to add a 3D surround sound effect to your audio if you want. On the topic of using the booster function, just know that things already get distorted at the 125 mark. Use it carefully to prevent any permanent hardware damage.

Dial in those frequencies

In conclusion, Extra Volume Booster Equalizer is great for changing the sound signature of your audio. You can use the sliders for granular adjustments or the built-in presets, and they both work well. Volume booster is less handy as it just causes a lot of distortion which could damage things. Use this one sparingly or not at all if possible.
