I’ve been using the JBL Tune Flex for only four months, and the left earbud has completely stopped working. It doesn’t charge, the light doesn’t turn on, and it won’t connect to my phone.

I’m seriously disappointed with my JBL Tune Flex earbuds. Even though they show a full charge in the case, the moment I start using them, they suddenly drop to “low battery” and shut off within a minute. This happens with both the left and right earbuds—so it’s clearly not an isolated issue. The cha...
I bought my JBL Wave Flex earbuds just about 4 months ago, and now the right earbud has completely stopped working. At first, I noticed that the battery on the right side was draining much faster than the left. But now it’s not showing any signs of life at all. There’s no LED light, it doesn’t show ...
