Is there any benefit to this if I don't listen to Hip-Hop/RnB/DubStep etc?
It's just an EQ, if you want EQ then use PowerAmp or DSP Manager and tweak things properly.
It it actually processing the audio in any other way, or is it JUST EQ? If so, then can someone work out the frequencies & value changes, then we could just make a "Beats Audio" profile for DSP Manager.
A software DSP can't totally compensate for poor hardware such as the Yamaha chips in the later model Samsungs.
