I notice quite a bit of difference in audio boost, even just changing different music types ie: dance, rock, jazz, etc. Of course it only works with headphones, or in my case I have an adapter that converts mini usb to 3.5 and another adapter that takes a male 3.5 and outputs R & L RCA jacks, plug it into my surrond sound and it's amazingly clear sound and you can really see the difference in the audio boost. Also make sure to check the box to the upper right to enable boost.
