What's new in this version:
Version 3.0.2 may include unspecified updates, enhancements, or bug fixes.
Whether you're playing games, watching videos, or listening to music it really adds depth and clarity to your audio outputs. No hardware required, just download and click on the button for your preference (gaming, music, or movies).
A further increase in bass would be cool, but I have a feeling that is coming out in the next product release.
The product sits on your systray and doesn't take up much for resources at all. It's very simplistic, but that's not to say it's a "cheap" product. It's professional audio quality in a consumer offering.
