My Sennheiser PC 350 SE headphones just broke recently where the right earpud broke off when it fell from atop my computer how to disassemble them so I can solder new wire to them? First image is what im trying to find out how to disassemble so I can solder new wires to a deeper part so itll be a stronger connection as when i tried to solder here when trying to put the metal part in second picture, the wire snapped there are screws in the 2 holes in first picture but dont seem todo anything in terms of opening it. If anyone has any idea from opening other similar headphones.
