Electronic – the name of the mentioned component

I have a pair of GRDE GL019 earbuds. One of those cheap ones, but fits me really well and has a great sound , hence i am taking so much pain to repair it.

I want to replace the mentioned/marked connectors in the picture, but dont know what are those called, and where can i find them online. These points are for contact charging the buds. BAsically, when i close the box the buds charge. So my guess is, there is some kind of spring mechanism inside those connectors whcih dont work anymore.. I can only see J1 and J2 (guessing those are just codes for connectors).

Any help would be really appreciated.

Thank you.
