JBL Charge 4: JBL Charge 4 speaker suddenly stops playing sound

Wed, 19 Feb 2025 23:29:04 -0700

My JBL Charge 4 bluetooth speaker was working fine until it suddenly stopped playing sound (even the ones it plays when it turns on, off, etc.). I don’t know what could’ve caused this since I don’t use the speaker on max volume. Speaker was charged and it connects fine, hasn’t gotten extremely wet either.

JBL Charge 4: Why is my speaker turning off

Sun, 10 Jan 2021 03:44:32 -0700

I press the power on button on my charge 4, it connects to my phone, then about 10 seconds later it shuts off by itself. I’ve charged it multiple times, factory reset it and it’s still doing the same thing. It just shuts off after about 20 seconds.

JBL Charge 4: I cannot press the power button. Wondering why?

Thu, 15 May 2025 18:09:39 -0700

Hey guys.

Just wondering if anyone here has ever experience trouble with their JBL speaker.

I have this JBL Charge 4 that I recently purchased 2 months ago.

Just now the speaker's power button seem to 'disappear' in a sense that when I press it, I cannot 'feel' the button and there is no clicked sound. As a result, I cannot turn my speaker on.

Other buttons are still normal, you can press it and there's that clicked sound. However that is not the case with the power button.

My speaker is still new, never drops to the floor nor being exposed to water.

I’ve browsed the internet and haven’t seen forum discussing this problem.

Wondering if anyone can advise any solution?

Thanks heaps!

JBL Charge 4: Speaker turns itself on when not plugged in?

Tue, 17 Feb 2026 15:31:52 -0700

I bought this speaker because the seller said that it would not power on. I played around with some of the button combos and reset the jbl and now got it to power on. I tested it with service mode and made sure it is not in service mode. The problem is when I turn the speaker off while it is not charging, it automatically turns itself on (even if it isn't connected to anything via bluetooth). The weird thing is that when it is plugged in, it works fine and will stay off when turned off and works fine in general. I have tried all the different suggestions and even took the battery out, nothing has worked.

Hey guys! Like i said in the title i got a brand new JBL charge 4 , a good speaker, after 1 week i tried to activate the low frequency mode but i pressed ,by mistake ,bluetooth button and volume up button which i later understood is a combination for reseting your speaker. The problem is that my speaker does not turn on but if i connect it to a power source i get the turning on sound and the power button is lighting white. Any ideeas who to fix it?

I solved the problem by pressing the bluetooth button and play button in the same time for some seconds with the speaker pluged in to a power source.

JBL Charge 4: Why are no buttons working except for the power button and led lights

Thu, 26 Mar 2020 23:34:59 -0700

My charge 4 was working good just a week ago. Now I can only connect to my phone because the Bluetooth button is not responding only the power button is responding so I cannot connect to new devices, change volume or any other button related functions. Also before I noticed the buttons weren't responding I noticed that the LEDs at the bottom were also no longer reflecting the speakers battery life but rather just dots blink with a black dot between them. Please help me guys! I attached pics

JBL Charge 4: Cannot connect JBL charge 4 to JBL charge 3 in stereo mode.

Tue, 28 Jun 2022 18:26:57 -0700

When using the JBL connect app, the app will not allow me to connect my JBL charge 3 to my charge 4 in stereo mode; it instantly defaults back to party mode every time I try. Has anyone else had this issue? Both firmware’s are up to date on each device and the JBL connect app is up to date aswell.

JBL Charge 4: I turn my device on, but it turns itself off within 5 seconds

Sun, 25 Jan 2026 10:17:59 -0700

I have recently replaced the battery in my JBL charge 4Q due to the old battery having a buldge. But now when it is powered on, it does turns off within 5 seconds. The battery indecator says that it has a full charge. Is there a way to reset the device to factory settings by constacting some pads on the motherboard? if no, is there anything i can do? (the original batttey is unusable). Also, when charging, the light indecator does not change, even if the battery is full.

JBL Charge 4: My speaker won’t stay charged and sounds muffled.

When I plug in my JBL Charge 4, it lights up and acts like it is charging. However, once I take it off the charger it dies immediately. The even bigger concern is that when I play music the speakers crackle and sound muffled.

JBL Charge 4: Bluetooth speaker audio blinking

Thu, 18 Jun 2020 10:05:18 -0700

Some times when using my JBL Charge 4 the audio will start coming in and out in roughly 1 second intervals. Usually I go through disconnecting, reconnecting, and eventually restarting the speaker before the audio will continue in a smooth manner. Any ideas for the cause? What could be an efficient way of fixing the audio problem quickly when it starts?
