A while ago HTC signed a deal with, Beats audio to integrate their audio into their devices, and people without HTC phones felt left out. But, now thanks to XDA Developers member RockoDev, he has unofficially brought beats audio to all Android devices. Granted it won’t work as well as it does on HTC devices, it will still improve sound overall.
You must be rooted to install this on your device, and of course with all things root there is always a risk of harming your device so be careful.
Some users are reporting better sound quality with better bass as well. The process of getting beats audio on you device can be found here on XDA Developers.
