Why Does My JBL Speaker Sound Muffled: Problem And Solution

Is your JBL Charge 3 speaker creating bad sound? JBL Charge 3 speakers are also afflicted by a number of different problems, and can sometimes make distorted or muffled sounds.

At audisok, with our experience, to find and fix the problem with your speaker, please review the following possible causes.

Why Does My JBL Speaker Sound Muffled?

the sound from your JBL speaker being muffled

1. Abuse Of Loud Volumes And Strong Bass

As a result, speaker cones have limitations that are unavoidable in nature. For example, when we turn up the volume or play bass heavy music, coning movement is restricted.

This restriction in turn causes the sound output to be muffled. These constraints must be recognized by both the speaker designer and user in order to achieve maximum sound quality.

Solution: Adjust the listening volume and bass.

My experience is that the best sound from your JBL speaker can only be attained by adjusting the bass levels and dialing down your volume. Do not set the volume too high. High volume, especially with heavy bass tones, aggravates muffled sounds.

These settings must be adjusted sensibly for you to enjoy crisp, clear sound from your speaker.

2. Wrong Audio Mode

If you’ve set your JBL speaker to an inappropriate audio format, it may produce muffled sound. The reason is that when the speaker isn’t in the right mood, it won ‘t reproduce sound frequencies well.

You have to choose what kind of audio approach is most appropriate for your content, so as to sound as clear as possible.

Solution: Return to the speaker’s audio preset mode.

In addition, we suggest that you set your speaker to its preset mode. This environment increases the power of the speaker’s performance, so that you will get the best sound quality possible. This is an important step in getting the most out of this mode.

3. Dirty Speaker Grills

Dirt and debris buildup is one of the most common reasons for poor sound quality and distorted speakers. Gradually these particles can collect inside the speaker, affecting its internal components.

When dirt collects on the speaker grills, it blocks sound emanating from the speaker. This causes distortion. For clear, high-quality sound the speaker grills need to be regularly cleaned and maintained.

Solution: Clean your JBL speaker grills

Dust also easily blocks and distorts the sound. So it’s necessary to clean your speakers regularly. A soft, damp cloth and a toothbrush with downy bristles are best for gently wiping off any dirt that may have accumulated.

In addition, making sure that your JBL speaker and audio sources are fully charged will result in improved sound quality. A fully charged speaker is also more capable of producing clearer.

4. Inaccurate Equalizer App Configuration

Inaccurate Equalizer App Configuration

Another problem might be incorrect equalizer settings, which could affect your JBL speaker’s sound quality.

However, equalizers are an indispensable part of balancing sound frequencies. If these settings are not set up correctly, they will certainly affect the sound quality of your speaker.

According to your type of audio, these settings may need checking and fine-tuning. We would suggest you do so for best results.

Solution: Correct your equalizer App settings

If you are using an equalizer app, review its settings. If the app is set up with a flat EQ, we suggest switching to another preset.

If this doesn’t work, we suggest that you go ahead and adjust each of the frequency bands to your liking.

5. Incorrect Volume Settings on a Receiver or Amp

If you are using a speaker together with an amplifier or receiver, we suggest that you experiment by changing the settings on these devices to see if this will resolve the problem of dull sound. In addition, make sure the speaker is firmly connected to either an amplifier or a receiver.

After these points have been checked and fixed, the sound quality of your JBL speaker should be greatly improved.

Solution: Modify the receiver/amp settings

If you have an amplifier or receiver attached to your speaker, please make some adjustments and see if this corrects the muffled sound. The speaker must also be securely linked to the amplifier or receiver.

Once these problems have been corrected, the sound quality of your JBL speaker will markedly improve.

6. Low Battery 

A low battery is, truly enough, one of the factors that can cause speakers to put out muffled sound. If either the speaker or the audio source is running out, there may not be enough power to produce clean sound.

But you must constantly keep an eye on the charge level and make sure it remains high to get good sound.

Solution: Charge your JBL speakers

If you find the charge on your JBL speaker is low or JBL speaker not charging , please plug it into a power outlet using the proper charging cable. A fully charged speaker usually provides better quality sound.

Moreover, don’t forget that your audio source device must also be charged. Good audio depends on powering both the speaker and the audio device.

7. Faulty Speakers

But this sound quality problem exists independently of which audio mode is selected, so perhaps the speakers themselves are defective. It is possible to play it up with excessive music with heavy bass played at top volumes until the speakers fail. To prevent damage.

You are advised to play bass-heavy music: low volume. If a replacement is needed, you can use the JBL Charge 3 Speaker Replacement guide as your reference for detailed instructions on how to replace the speakers.

Solution: Restart the JBL bluetooth speaker

When Should Your JBL Speaker Be Replaced?

When Should Your JBL Speaker Be Replaced

Another obvious sign that a speaker needs replacing is when no attempts to fix it can remove sound distortion.

Also, a large drop from its original levels may indicate that your speaker is coming toward the end of serviceable life. If it gets, for instance, ripped or torn or otherwise damaged in some way, then it’s clearly time for replacement.

For a JBL speaker, one should expect it to serve well for about 15 years before it needs replacing. Yet the duration varies, depending on frequency of use and maintenance.

If you use it with care and don’t overdo it, our own usage data shows that a JBL speaker could last longer than its standard lifecycle.

How Do I Reset My JBL Speaker?

If none of the above methods have worked to solve your problem, our last resort is to reset all settings in factory mode. This can resolve software bugs and Bluetooth connection problems.

Also, a reset will set the audio settings back to default, so assuming you haven’t tweaked them in the previous step it will be done for you now.

Please follow these instructions to reset your JBL Pulse 5:

  • Press the power button to turn on the speaker.
  • Press and hold the power button and volume button together for 2 seconds.
  • The speaker will begin a factory reset. Wait for it to finish up, at which point the speaker will be shut off.
  • Press the power button again to turn the speaker back on.

After resetting everything, you just need to attach your JBL speaker back to your phone and listen to the melodies of your choice

Wrapping It Up

Having a poor-sounding JBL speaker with which you can’t do anything without being extremely aggravated is one of the most frustrating things on earth.

In this guide at audiosk, we’ve looked at a variety of approaches to resolve problems like muffled sound and even cracking from the JBL speaker. Hopefully one of our suggested solutions has worked to resolve the problem for you.

But if it persists, then the speaker probably is defective. We suggest that you bring your JBL speaker to an authorized repair center for competent repairs.
