Discerning what each JBL Charge 4 button does when pressed can be challenging for first-time users. After all, JBL Charge 4 controls are in the form of symbols. You must know what each symbol signifies to get the best out of your portable Bluetooth speaker.

Here’s a breakdown of JBL Charge 4 button functions:

The Power Button

The power button is the third button from the left, next to the Bluetooth button. It has a circular symbol󠄵, and its primary function is to turn your speaker on or off. 

However, it has more than one function when simultaneously pressed with other control buttons.

When your JBL Charge 4 is OFF, you can turn it ON by pressing the power button once. The power button has a status light that will glow a steady white light to indicate that the speaker is ON.

If you want to turn your JBL Charge 4 OFF, press the power button once. The status light will dim out, meaning your speaker is now OFF.

Play Button

JBL Charge 4 – PLAY/PAUSE BUTTON

The play button has a flipped triangular symbol and is on the extreme right after the volume up button. Sometimes it is called the play/pause button because pressing it also pauses the playing track. 

This control button performs multiple functions, including playing, pausing, and skipping audio tracks. After pairing your JBL Charge 4 with a smartphone or tablet, pressing the play button on the speaker once will start streaming music from your device. Pressing the button once as the music is playing will pause it.

Even though the JBL Charge 4 does not have a next button, you can skip tracks by double-tapping the play/pause button. Press and release the play/pause button twice to advance to the next song. The only issue with this speaker is that you cannot go to a previous track.

Volume Up Button

The volume up button is between the Bluetooth and the play/pause buttons. As suggested by its description, this control increases the volume level of the speaker’s audio output.

If you want to adjust the volume to maximum, press and hold the volume up button for a few seconds. The speaker will emit a chiming sound when you reach the maximum volume. If you want to increase the level by just a bit, press the button once or twice. You will hear a tone with every press.

Volume Down Button

The volume down button has a minus symbol. The button is the second from the left between the Connect+ and power buttons, and its primary function is to decrease the volume level of the speaker’s audio output.

If you want to decrease the volume to a minimum, press and hold the volume down button for a few seconds. Conversely, press the button once or twice to reduce the level by just a bit. You will hear a tone with every press.

Bluetooth Button

JBL Charge 4 – BLUETOOTH BUTTON

The Bluetooth button is next to the power button. Its primary function is to put your JBL Charge 4 speaker in pairing mode so that you can pair it with your smartphone, tablet, laptop, or any other compatible device. It makes the speaker discoverable for easy pairing.

Enabling Pairing Mode on a JBL Charge 4

The Connect+ button is the first button from the right, next to the volume down button. It has an infinity symbol, and its primary function is to connect your speaker to multiple compatible speakers. The paired speakers play the same audio from the same audio source.

To use this feature, press the Connect+ button on the primary speaker. Press the corresponding button on all the other speakers you want to pair. After completing the pairing process, the music will play simultaneously on all paired speakers.

JBL Charge 4 Button Combinations (Secret Modes)

JBL Charge 4 – Secret Button Combinations and Functions

Here is a breakdown of JBL Charge 4 button combinations:

Service Mode

Service, or weird mode, is a feature in JBL Bluetooth speakers that makes your speaker temporarily unusable until you exit the mode. It locks the speaker and makes all the buttons unresponsive so that no one can interfere with the settings or the playing audio.

Many users often accidentally put their speakers in service mode when they press the Bluetooth and play buttons simultaneously. Once in service mode, your speaker won’t respond. No matter how hard you try, it won’t turn on or off. Fortunately, you can exit service mode using these steps:

• Connect your JBL Charge 4 speaker to a charger.
• Plug the charger into an AC wall outlet.
• Press the Bluetooth and Play buttons.

Press and hold for 10 seconds to activate/deactivate the Service Mode

• Maintain this position for 10 to 20 seconds.
• Release the buttons when the speaker turns on.
• Unplug the charger from the speaker.
• Test all the control buttons to see if they are responsive.

Low-Frequency Mode

Despite its size, the JBL Charge 4 is renowned for its thundering bass. But for some reason, you may wish to increase the bass. To do so, you must put the speaker in low-frequency mode.

Low-frequency mode reduces the treble and frequency of the audio output, increasing the bass as a result.

Here are the steps to activate low-frequency mode:

• Press the power button to turn on your speaker.
• Press the Bluetooth and Volume Down buttons simultaneously.

Press and hold the Bluetooth and Volume Down to activate/deactivate the LFE Mode

• Maintain this position for about 10 seconds.
• Release the buttons when the indicator light displays a steady white glow.
• Your speaker is now in low-frequency mode.

Follow the above steps to exit low-frequency mode. Release the Bluetooth and the volume down buttons when the white light goes off.

Reset JBL Charge 4

Software bugs can cause your JBL Charge 4 to malfunction or become unresponsive. Resetting the speaker can help fix this issue. A reset erases all custom settings and restores the speaker to factory defaults.

Since the JBL Charge 4 has no dedicated reset button, you must press a specific button combination to reset the speaker to factory defaults.

Here’s how to reset your JBL Charge 4:

• Press the power button to turn the speaker on.
• Press the Volume Up and Bluetooth buttons simultaneously for 10-15 seconds.
