JBL Charge 3 Extra Bass Mode Explained

You can change the bass response of the JBL Charge 3, by turning on and off its extra bass mode (EBM). In fact, when activated, EBM 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 EBM when playing the speaker loudly, say at an outdoor party.  This helps cut bass distortion. Plus, less bass means longer playing time before the battery runs dead.





How to Turn Off JBL Charge 3 Extra Bass Mode

First, by default, the JBL Charge 3 has EBM turned on, after a reset.  This adds a bit of extra treble and lots more bass to the audio output as compared to when this feature is OFF. While EBM often runs the battery out of power faster, the better sound it provides is well worth this bit of inconvenience.

You can turn EBM off by pressing and holding in the Volume Down (-) and Bluetooth buttons for about ten seconds, 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.

How to Turn On JBL Charge 3 Extra Bass Mode

Finally, to turn extra bass mode back on again, press and hold the Volume Down and Bluetooth buttons in until the battery gauge lights up again.  Then release the buttons.  When the battery gauge lights, EBM resumes once more. Note that you can also reset the speaker to reset EBM.
