The only custom I have that has any visible artwork is the Sleek CT6. My FitEar Private 333 has a graphic, but due to the outer headphone jack, it is printed on the inside. Lovely earphone by the way.
One thing I don't appreciate about the JH13Pro is that the 'technology' used to make sound exactly the same is the incredibly long sound tube. It is fine, but I feel closed in. On the other hand, FitEars Private 333 is slightly too short and thus, much less isolating. In the end, I hope it won't come down to marketing which will win the SQ wars between customs. But, probably marketing will win out.
