@FiiO Which exact pogo pin type do you use for the earpieces? On my UTWS5 they are corroded after a year.
Pogo pin is ~ 7.3mm long, 2mm thick on the thickest part, 1.5mm thick on the contact surface side.
The the battery also needs to be replaced, right now I´m putting in the battery of my less used MMCX UTWS3 and use it´s backplate where the contacts are still fine.
(I used it daily, battery protection for a 85% charging limit was activated all the time)
