Chosen Solution

Is there any way to turn off the VERY ANNOYING AND LOUD startup sound? I absolutely hate it so much that I will sell this speaker if I can’t get rid of that noise!

I can’t find the option to update firmware in JBL Connect app to disable the startup sound of my Flip 4. How do I update the firmware?

For Flip 4 the customer support answer is: Drin at Customer Service · 2 years ago Unfortunately, the notification sound can’t be adjusted. These are fixed feature settings which cannot be changed so not much you can do now - this is annoying ….

I have downloaded the JBL Connect app (Samsung S7), upgraded to JBL Connect+. Does nothing, except change name of the JBL Charge 3 and do upgrade again. How can I access the “turn off alert sounds”  ????? BTW: the app stays most of the time in “Discovering” mode (although BT works fine). Please help

The app only supports a handful of speakers. The Charge Essential is not supported. The On/Off sound is so annoying that my wife forbids me to use the loudspeaker if she is around. So, for this model, the only way to get rid of these blasting chimes is to not buy it in the first place… JBL confirms that this, indeed, is the only solution.

Yes i also hate that loudly sound of startup. In there anybody know how to turn it off?

No app named JBL Connect to be found in iOS App Store!!

It’s the JBL Connect app on android. First install the app / update it to the newest version via the play store. edit: this is the app https://play.google.com/store/apps/detai… Connect your phone via bluetooth with the box. If the app then prompts you to do a firmware update, plug the box in an outlet to charge and do that, this takes a while. When everything is up to date you should see your box on the main screen of the app like here https://imgur.com/LaUcEkL.jpg if you don’t see that try to restart the app, and make sure your phone is still connected to the box. Then tap on the grey gear on the bottom, and disable the option “audio feedback sounds”. This worked for my charge 3, hopefully it’s the same for your version. If you have iOS it should be similar, but I don’t know the exact details… I hope this helps :) IT WORKSç Thank yu JH

Effectivement pour la JBL Charge Essential, JBL que j’ai contacté confirme que le firmware ne peut pas être mis à jour et les bruits horribles au démarrage ne peuvent pas être supprimés sur ce modèle.

those using iOS should download JBL Portable from AppStore then connect their phone to the speaker via Bluetooth then connect the speaker to power source then option to upgrade firmware (the whole process is 3-6 minutes) will appear after upgrading it then look for feedback tone then turn it off. Enjoy your speakers

Solved the issue in 2 sec. Download the JBL portable (IOS). On first page you find the button to remove the sound.

All you’ve to do is right-click on the Sound settings in the bottom-right corner of your Windows system tray, and select Sounds. The Sound settings dialog box will be launched. From there, uncheck the Play Windows Startup Sound checkbox, and click on OK. Regards, Peter
