It seems to be good, and then you turn it off, and everything sounds worse. So you think to yourself, "Huh, it must be doing something" - Then you disable the add-in, and everything sounds the same as when it is turned on.

I genuinely cannot tell if this actually improves audio quality or not. Add to it that this actually breaks video functionality on a numerator of different sites that host video content (No, YouTube is not one) - And the downsides of this plugin outweigh the (maybe) benefits.
