my ANRY AIR2 TWS just arrived, and after testing them for like 10 minutes, the left one doesnt turn on or charge. Any ideas what can I do besides dispute ?

it was freebie

Just got my DIY T12-952 Oled soldering station freebie from Laecho (chinks says that they are were called Quicko)
So far so good. Made some safety fixes but it looks promising.

They are properly grounded, checked with multimeter :)
Thanks for the tip
