One bud got driven over by a car.

I tried to put my Buds in and while i held onto the one i tried to get, my other bud and case were accidentally dropped. The bud in front of a car, the case only got some cosmetic damage cuz it flew the other way. A replacement bud seems to be $160😨. Is there any way i can fix these? How do i find out whats broken/disconnected? For being driven over the damage could have been worse in my opinion. The metal part is partially open and the part inside the metal part and that in the plastic part seem to be disconnected. Any way of me fixing this?
