You can change the bass response of the JBL Charge 3, by turning on and off its extra bass mode. In fact, when activated, this mode makes the passive bass radiators vibrate a lot more. This also adds a rumble quality to the playing program. But you may wish to switch OFF bass mode when playing the speaker loudly, say at an outdoor party. This helps cut bass overload when playing very loudly.
How to Turn On JBL Charge 3 Bass Mode
First, by default, the JBL Charge 3 has its bass mode already ON after a reset. Bass mode also adds a bit of extra treble but lots of extra bass to the audio output as compared to when this feature is OFF.
You can turn bass mode ON or OFF by pressing and holding in the Volume Down (-) and Bluetooth buttons for about ten seconds.
Then hold these buttons in until some of the battery gauge lights come on, as shown in the next picture.
Find the buttons on the top of the speaker, as shown in the picture above.
Finally, to reverse what you just did, press and hold the Volume Down and Bluetooth buttons again until the battery gauge lights up again. Then release them.
Next, when the battery gauge lights come on, the bass mode switches back to what it was before.
