You can choose from a list of equalizer presets in iOS to adjust how you hear music from your Music app on your iPhone, iPad or iPod touch. The best way to use it is to play some music and try different settings. The Late Night setting is a little different as it applies to video as well. You can use iTunes on your desktop computer to get an idea about what each preset is doing.
