I had to use an alternative battery like a phone charger with USB while it's plugged up. Try to see if you can get your earbuds to flash the three lights showing that it's charging let it charge for a little bit and it might actually still charge. I haven't found any other source but this forum speaking about the vibe 300 tws series. I kinda gotta baby it until I can find a replace case. Which is apparently on Amazon go figure. But still jbl did good on the quality of sound for the price.
