Interesting point! I've never seen the t-shocks fall out but this makes sense. Definitely don't want to squeeze anything too tight with those screws. Best to get a nice new set of ear stem washers... I like the ones @scienergy sells personally, but Linegear makes excellent ear stem washers as well!keep in mind sometimes if the temple shocks won't stay in it means the washers in ear stems need to be replaced. when the washers wear and the arms feel loose people tighten down the screws on the hinges. eventually they get tightened down far enough that it squeezes the frame down enough that the rubbers get pinched and don't want to stay in.
