Anyone else have a fostex headphone where the little screw that holds the yoke to the earcup is loose? I have the TH900 Mk2 but my TR-X00 ebony also has the same mechanism. the screw is loose but I cannot get at it because the actual earcup is in the way. How do you tighten the little screw that holds the earcup yoke in place? I see it is loose but I cannot get at it! very frustrating!
