JBL Flip 4 Flip4 Speaker Distorted Sound - Bass Problem - Red LED Flashing - Short Playtime Battery

Popping noise, similar to the sound of Tearing Fabric during low-frequency sounds - Bass usually indicates a faulty battery.

This is often accompanied by the battery level indicator going from full to empty (red flashing LED) in a matter of minutes.

If the fabric cover - grille is removed and you listen closely to both speaker drivers you will not be able to identify from which speaker driver the popping noise is coming - it will be coming from both or alternate between the two.

The faulty battery is unable to provide enough current to the amplifier to sufficiently drive the speaker drivers and sound distortion occurs. Sound distortion usually ceases or gets better when JBL Flip 4 is connected to a charger.

Often a faulty Li Ion battery bulges; appears swollen or inflated because of the internal gas buildup.
