The case was made for transportation and not for storage purposes I guess. However playing with the foam is a good option though.To me detaching the cable each time is completely out of the question. Even with my Clear that uses easier to connect 3.5mm plugs, it is out of the question.
Therefore the Empyrean case (as it comes) is completely useless to me, as it is the Clear case. However the Empyrean case can be corrected by changing the foam inside, while with the Clear case that is not possible.
However the problem is not only keeping the cables attached, but also keeping the pivots position (set for our head size), which are even more difficult to reset and set each time.
Additionally even with the pivot fully retracted, if we are not very careful, the golden pivot can touch the case hinge and get scratched. It should not be so close to the hinge.
So for all these 3 reasons the foam cutting is not appropriate. So much space inside the case wasted and there is no adequate space for the actual headphone in ready to use state. Fortunately this is fixable by replacing the foam.
I myself will be happy with my omega headphone stand which I think provides enough dust protection as the cups are sealed on the stand. And I don't even have to worry about resetting the pivots.
