Do you need to adjust your sound quality when listening to music on your Android device? Well, I have been using DSP Manager and other apps that require custom ROMs but found this really great app that does it on any Android device, no rooting required.
The Equalizer app for Android works out of the box flawlessly (on ICS) and can provide you with quick sound adjustments for better quality listening. I think this is a great app that works well across many Android devices and works instantly.
Give it a go and let me know what you think of this app if you like listening to music.
