JBL Flip 4 Bass Boost

You can change how loud the bass is on the JBL Flip 4 Bluetooth speaker, by turning on and off its bass boost mode. When ON, this mode makes the passive bass radiators on each side of the speaker vibrate much more.  Plus, bass boost adds an extra rumble quality to the playing program, that travels pretty far from the speaker.  So, for you boom warriors, this post walks you through how to use this mode, so you can get that extra umph.

How to Turn Off JBL Flip 4 Bass Boost

By default, this speaker has bass boost mode turned ON after a reset.  This adds a bit of treble and lots of extra bass to the audio output as compared to when this mode is OFF.

You can turn bass boost off by pressing and holding in the Volume Down (-) and Bluetooth buttons as circled in green in the next picture.

Hold them in for roughly ten seconds, until the Power and Connect buttons light up white.  See these lamps lit up in the previous picture.

JBL Flip 4 Bass Boost: How to Turn On

To re activate bass boost once more, press and hold the Volume Down and Bluetooth buttons in until the Power and Connect buttons light white.  Then release the buttons.  When these buttons above light together, bass boost has resumed once again.

Warning

The unit really thumps when you switch ON bass boost.  So be warry of how loudly you play this speaker with the bass boosted, to avoid breakage to the speaker drivers. If the bass is crackling, snapping, tapping, or otherwise distorting, turn it down !
