When the androids flick their earrings during a fight, does it do anything in particular, 或者 do they just do it for fun?

i think just for fun

When they flick their earrings, it gives them power to do a special technique (or it just gives them power overall).

it makes the androids 更多 powerful. if 你 watch the history of trunks, 18 does it right before she attacks and pretty much gets healed. So the earrings are sort of like senzu beans.

yeah i think it gives them power.
