Hi Arthur , I do use Sonarworks on my speakers and the mixes translate very well to other systems, 
 
	I do not use Sonarworks for my headphones , Morphit is much closer to my speaker eq.
 
	I use Shure SRH840 headphones. I would expect Sonarworks to be closer but they are not.  
 
	These Headphones are not calibrated buy Sonarworks.  That maybe an option for you is to buy 
 
	a calibrated set from them.   In the mean time I would do a mix using Morphit and a mix using Sonarworks
 
	and see which mix translates better to other systems ,   That is what counts ,
