Jabra Elite 5 (buds) not charging
recently bought a jabra elite 5 (brand new in box) and the earbuds are not charging. when i took the earbuds and case out of the buds they seemed to be completely dead, however when i plugged in the case its led it up. after about 1-2 hours of charging the led on the case lit green but the buds are still "dead". i tried cleaning the gold contact points but to no avail. i have heard that earbuds stored unopened for a long period of time can be deeply discharged and stop working. what can i do to hopefully revive these buds?
note: this pair of earbuds seemed to be produced/manufactured in 2022-2023, so i am very concerned about overdischarge killing the buds.
edit: i have tried charging overnight (about 11 hours) however the buds still seem dead
