Head to Settings -> Sound when you've headphones plugged in and the Sound Enhancer option should be selectable, you can choose between different profiles there.

 

Me too, I totally couldn't understand why the enhancement options were so limited!

If you select Beats, there's a pull down in the top left hand corner of the screen, you should be able to select which Beats profile you want from there. There's 5 I think.

 

Ok So I read this Beats Audio only works with headset plugged in so I am assuming regular headset not a bluetooth one is that right?

The Beats Audio works over Bluetooth to my Philips Dock, so i am gussing it should work with Bluetooth headphones as well.
