How to Bass Boost JBL Charge 4 Speaker

You can adjust the bass response of the JBL Charge 4, by turning on and off its bass boost mode. Now shen ON, bass boost makes the passive bass radiators on this speaker vibrate a lot more, and adds a decidedly “thumpy” quality to the content playing. But when OFF, you get a more flat sounding, less bassy response.
