Maybe keep scrapping the sticky adhesive to see if there are screws hidden in that frame around the driver. Thats the where the screws are hidden on all the ATH electrets. With a popsicle stick or some other soft wood poker you could push all that black tar like adhesive without scratching the plastic. Hopefully there is some sort of screw fasteners there to open up the cups for you. Very curious about the dampening scheme and how truly vented the backs of those cups are.
