Have you tried VOODOO Louder? It's a software solution that uses the SGN's audio hardware to increase headphone output. By default, the Note doesn't use all the volume at it's disposal. VOODOO Louder allows you to do just that.

i used voodoo louder on my SGS2, didn't actually know that it was for the NOTE as well...
i allready flashed the file with the Beats audio, can't hear any diffrence, can somebody help me with a flashable file to get back the stock files, so i can use Voodoo louder
