Why is my JBL speaker crackling?

• Dust and debris. Accumulation of dust can interfere with the speaker’s function.

Ways to fix crackling noise on JBL speaker

Dealing with a crackling JBL speaker can be frustrating, but these troubleshooting steps often offer an effective solution.

Adjust the volume

Sometimes, simply lowering the volume can reduce crackling noise. Test your speaker at both high and low volume levels to see if there’s any difference.

Check Bluetooth connectivity

Ensure that your JBL speaker is within range of the playback device and that there are no obstructions or interference sources nearby. Try repositioning the devices or switching to a different Bluetooth™ channel to minimize interference.

Reconnect the speaker

Unpairing your speaker from your device lets you re-establish a stronger connection between the two. Try unpairing and re-pairing your phone and the JBL speaker.

Clean the speaker

Does your speaker need some TLC? Dust and debris can accumulate on the speaker drivers and affect sound quality. Use a soft brush or compressed air to gently clean the speaker grille and drivers, removing any dirt or debris that may be causing interference.

Check for water damage

If you use your JBL speaker in the bathroom or near the pool, it’s more likely to come into contact with moisture. If you suspect your speaker has come in contact with moisture, give it a good shake to get rid of any excess liquid and then allow it to dry completely before trying to power it on again.

Test different audio sources

Connect your JBL speaker to different audio sources, such as a smartphone, tablet, or computer, to determine if the crackling noise persists across multiple devices. This can help isolate the issue to either the speaker or the audio source.

Update the speaker’s firmware

Software updates are how your JBL speaker stays current and solves known software problems. Ensure your speaker’s software is up to date for optimal performance.

You can download the JBL Portable app from the iOS® App Store® and Google Play™ Store. If there’s an update available, a small red dot above the settings gear icon.
