Unfortunately, the usual way how to put JBL Charge 5 in low frequency mode does not work. Hopefully, JBL will re add this feature in a later version of the firmware. But if this did work, it might work as it has on other JBL Charge speakers. Now when ON, this mode makes the passive bass radiators vibrate noticeably more. Furthermore, low frequency mode adds a decidedly “thumpy” aspect to the content playing. And this would make this speaker sound much bigger than it really is.
How to Put JBL Charge 5 in Low Frequency Mode
First off, by default, this BT speaker would have low frequency mode ON. Moreover, if this toggling actually worked, this would also add more treble and lots more bass.
How to Switch OFF and ON
Someday we hope that you’ll be able to turn low frequency mode OFF. This would work by pressing the Volume Down (-) and Bluetooth buttons. You would hold them in for about ten seconds. Hold until the oval ring around the buttons lights.
Also, to turn low frequency mode back on, again, press the Volume Down and Bluetooth buttons. Hold them in until the oval button ring lights up again. Then release the buttons. Finally, when the ring goes off, low frequency mode resumes once more.
One reason they did not include this mode in the firmware might be because of the resulting shorter battery life. The more bass as it turns out, the less play time per charge you get. So it’s understandable why some authority decided to omit this feature. But still, we wish they included it. If they had, us customers could choose more bass ourselves if we didn’t care about shortened play times per charge.
