How to use ViPER4Android FX to improve the sound on your Android

There are certain basic elements about life and nature that humans have been trying to perfect for ages. The attraction that the human ear has to the sounds and music, in general, has led to the creation of musical instruments, sound devices and a billion-dollar music industry that is not only a source of inspiration and entertainment but a livelihood for many.


Mobile phones have been designed to be the all-in-one replacements for the outdated portable music devices, but they are capable of doing so much more. Apart from offering music seamlessly through online services, the ability to fine-tune the hardware and software of Android devices makes them the perfect specimens for audio equalizers such as Viper4Android.

What is ViPER4Android FX?

Developed by a popular audiophile who goes by the name ViPER520, this piece of technology is designed to be the ultimate equalizer app. The ViPER4Android FX app comes with built-in support for sound drivers that can fine-tune the sound for Headphones, Speakers, and Bluetooth Audio devices separately.

The only reason you cannot find ViPER4Android FX on the Google Play Store is just like most of the hardcore apps, it requires root access.
