Do you find it hard to listen to music on your smartphone? Or have trouble hearing your friend's conversation? If so, then this Equalizer app is a must-have on your phone. It can boost sound up to 30% louder than the original.

You don't have to worry about the quality of the sound; this app doesn't change the audio in any way. It is completely free, so you can try it out for free.

To use this Equalizer, first, open the app and click on the "Boost Volume" tab. You will see a list of devices. Select your device and boost the sound. You can also boost volume for individual music tracks.

If you are using a tablet or a smartphone with a low-quality screen, then you can select the "Low Resolution" option to get the best quality.
