final solution to Jabra Elite charging problems: how to make them charge again

I have Jabra Elite 85t and they stopped charging.
I used all solutions proposed online and none worked.
However I noticed that the magnete on the right headphone was "weak": this means that it doesn't make a good contact with the pins inside the charging case.
If the magnete is too weak, the pins are not depressed and there is no contact between the pins and the headphones.
Solution: some toilet paper
