Despite a ridiculous amount of time troubleshooting and fixing a pairing issue between the buds, several months ago I started using my ZOLO Liberty product.
I use them for workout, and I keep them inside their charging case correctly plugged within a bag pocket together with a locker, clean clothes and my gym digital access key.
After a month without going to the gym, I come back, turn on the bluetooth but only the right earbud behaves normally. As title suggests, left bud looks completely dead for no reason. Pressing the button does nothing at all, putting it back into the case doesnt even make the led blink.
What the devil happened?
How do I fix this?
