Yeah the washers prevent metal-on-metal rubbing when you open/close the earstems, so it's better to replace them than just tighten the screws. Even though it's a pain in the ass...
Regarding the original topic, I think this has been asked before. Personally, though it's subjective for each person, my threshold is when they no longer will sit firmly on top of my head - it's very annoying when they keep falling back down. Even worse, if you tilt your head back and they fall off backwards...
Are those Washers hard to get ? If one arm of any X Metal is loose I just screw it with the T6 Screwdriver.
So just need to look after theís Washers too then.
Thanks for advice
