Every few months, I get again cracking pop static noises in my JBL Link 300 and JBL Link 20.

The only (simple) resolution is to fully reset it. But with a specific way !!!

JBL 300: If you long press the mute buton, it won't be solved. And pPressing the reset button at the back does nothing. You have to hold down bluetooth and volume+ button together for more than 10 sec. Then reconfigure the JBL with Google Home, and voilà !

for JBL 20, Hold down mute button for about 7 seconds until wifi light turns off. Then hold down both mute and power button for about 20 seconds.

Great !!! You saved my life.. well, actually the life of my best friend whose PC's HDD died yesterday...

The most difficult part was with removing the cables fixed with two black retainers... I have been pulling on those like crazy... Fortunately nothing broken and the PC is now booting (Useful also: find a good paper on how to install windows from a usb key! )
