How do I fix my JBL speaker distortion?

One of the issues that you might experience with JBL speakers is when it has a distorted sound or the sound quality is not that good. You might be hearing some static noise when you play music. This can be an annoying experience especially when you are listening to your favorite music.

Here’s what you need to do to fix the sound issue on your JBL Boombox 3 speaker.

Solution 1: Restart the JBL Boombox 3 speaker

One of the main causes of static noise or other sound issues on your JBL Boombox 3 speaker is a software glitch. In order to fix this you should restart the JBL speaker in order to refresh its software.

Restarting JBL Boombox Bluetooth speakers

Press and hold the power button until the JBL speaker turns off.

Wait for at least a minute.

Press and hold the power button to turn on the JBL speaker.

You will also need to restart the Bluetooth device the JBL Boombox 3 speaker is connecting to. Once the Bluetooth device has restarted place both devices in pairing mode then check if the sound issue still persists.

Solution 2: Reduce the volume of your JBL Boombox 3

Sometimes playing music at max volume will result in a sound distortion on your JBL speaker.

There are various factors that can cause this such as a:

• JBL speaker limitation: Portable speakers have a limit to how loud they can play music without distorting the sound. When the volume is turned up too high or is set to max volume, the speaker’s components can no longer accurately reproduce the rich audio spectrum, causing distortion.
• Power limitations: The power amplifier in the speaker may not be capable of delivering enough power to the speakers to maintain a clear signal at high volume.
• Signal overload: If the signal being sent to the speaker is too strong, it can overload the speaker’s amplifier and cause distortion.

To fix this you should try listening to music at lower volumes. You should also try adjusting the bass setting as a much deeper bass will also cause distortion.

Solution 3: Check the audio source

Sometimes the sound distortion you experience on your JBL Boombox 3 speaker is due to the audio source. If you are using a third-party app to play music, try switching to a different app or source to see if the distortion is isolated to that particular app. You should also try playing a different soundtrack or music genre to check if the issue is caused by the particular music you are playing.

Solution 4: Update the JBL Boombox 3 software

There’s a possibility that an outdated JBL software is causing this problem. To fix this you just need to install the latest software on your JBL speaker.

• Tap Let’s party to complete the update.

After the latest update has been installed try checking if the sound issues still occurs.

Solution 5: Charge the JBL Boombox 3

One of the reasons why JBL Bluetooth speakers will sound like faulty speakers is because of a low battery life. Try charging the battery first for 6.5 hours or until the battery charging indicator shows that the battery life is already full.

• Use the provided AC power cord only and connect it to the AC power port of your JBL speaker.
• Connect the other end of the AC power cord to a wall outlet then wait for the charging process to complete.

After the battery life is full try checking if the JBL Boombox sound issue still occurs.
