Best sound amplifier app. It does work! You have to let the music play in the background and be on this app. Kudos to the developers. Thanks for this great app！
The excellent app really if it increases the volume in the cell. And in the headphones and speakers the equalizer is heard very very well, the low, middle, and high ranges, and without distorting！Everything 100% my congratulations to the developers of this app.
