JBL Flip 4 makes no sound

There is no sound from bluetooth, aux and even system sounds do not work. LEDs are blinking, but I hear nothing even when I turn speaker on/off or toggling bluetooth/pairing mode.

Update (11/01/2020)

Hi guys, thank you all a lot for the answers but my speaker now started to work fine by itself somehow.

Ummm hello im laye but i have a solution. theres is a small metal box soldered into the pcb in the left side (where the strap is) so you have to open the jbl, remove the left driver, and then put something to hold the small metal box pushed to the pcb to make contact. I know this us a bad explanation of what is going on but if you want more or want to thank me, please dm me in instagram @zisimopoulos_jr

Also here is a video for explaining

The video is with a jbl flip 3 but it works with jbl flip 4 too.

Hope ive helped…

It works ! Thanks a lot Νίκος


no problem bro... i put a soft rubber underneath but it broke in a week so i used a hot glue gun stick and cut it with scissors to be more durable... If you have soldering experience i suggest you resoldering this chip, but if you haven't got any then dont do anything... Its very easy to mess up.


sorry but this is not a helpfull answer because we have non sound at all! as if the speaker was disconnected


You can see the comment i posted a while ago to try fixing it yourself


Hi !

I have the same problem :-(

Did you succeed in fixing it ?

plug in the charger and hold down the power button..wait a second and then you should hear that your phone has connected to it . mess around with the buttons if still not working or disconnect your whole phone from it and then re due it .

I had the same issue, I performed the steps to reset it and didn’t work, but then I tried to use Siri and then it worked.

Worth the shot
