Why Does My Bluetooth Speaker Buzz?

When it comes to connecting devices, Bluetooth speakers are the most reliable option because they are simple to use. However, from time to time, you may hear a buzzing sound, also known as static noise, that will interrupt your listening experience. 

Despite the fact that this interruption can be quite inconvenient, it is something that can be easily remedied. In this article, we’ll go over some of the reasons why your Bluetooth speaker might be emitting static noises.

What is the source of the buzzing in my Bluetooth speaker?

Your Bluetooth speaker may buzz for a variety of reasons, including electrical ground loops, low battery, distance, interference, outdated software, audio cable quality, an outdated music app, and faulty Bluetooth speakers. Electrical ground loops, low battery, distance, and interference are all possible causes.

Electrical Ground Loops are a type of ground loop.

It is possible to create a ground loop when one or more devices are plugged into the AC (alternating current) at multiple locations and are connected by electrical signal cables (RCA, HDMI, component, composite) that have shielding that is connected to the earth. 

Ground loops are a common occurrence, and they are characterised by a loud hum or buzz that emanates from the speakers themselves.

Anything that breaks the loop can be used to remove the noise from the system. It is simple to accomplish this by using a single alternating current (AC) socket to power all of the devices.

In the event that you are unable to reach the same outlet with a piece of equipment, an extension cord can be of great assistance to you. You can also purchase a hum eliminator such as the Ebtech’s Hum X if an extension cord is deemed impractical for your particular situation.

Battery life is dwindling.

When was the last time you topped off the battery of your Bluetooth speakers with juice? While your speaker’s battery life may be impressive, allowing the battery to run down to a dangerously low level may result in a buzzing, crackling, or static sound. 

This occurs because, when the power is low, the Bluetooth connection becomes weaker, causing your speakers to begin experiencing problems with the sound quality they produce.

When your battery charge is low, your speakers begin to make noise, and if the charge is too low, the sound is completely turned off. If you want your speaker to perform at its best, make sure that it is fully charged before using it to avoid this problem.


Another factor that could be contributing to the buzzing sound produced by your Bluetooth speakers is the distance between the speaker and the device with which it is connected. The fact that speakers have a range of approximately 10 to 20 metres means that when the range is exceeded, static noises may be heard.

When you notice that your Bluetooth speaker is buzzing, it should be a clear indication that the distance between you and the speaker has exceeded the range that is permitted. As a result, you may want to remove any obstructions that are present between your speaker and your device to ensure that your Bluetooth connection is as strong as it can possibly be.

Because they have a shorter range than speakers, Bluetooth headphones are more affected by distance than speakers. Keep your device and speakers as close as possible to each other to ensure a strong connection.


Other devices in the room may cause your Bluetooth speakers to buzz because they are interfering with the sound quality of the speakers. When you notice that your speaker is suddenly emitting static noises, you can determine that this is the source of the problem.

Similarly, devices that are also using the Bluetooth connection and are in close proximity to your speakers may cause interference with them. Additionally, WiFi devices, like Bluetooth devices, may cause interference with your speakers due to the fact that both WiFi and Bluetooth connections use the same radio frequency of 2.4 GHz.

If you are experiencing static interference from your devices, you can reduce the amount of static interference by removing any devices that are in the way of your Bluetooth speaker and your phone or media player. Switching the other devices to the 5.0 GHz band will help to further reduce interference from other devices.

Software that is out of date

Our Bluetooth speakers’ software updates are frequently overlooked, and we are guilty of this ourselves.

The long term consequences of this could be detrimental because the sound quality of your speaker will be compromised as a result of the outdated software that is running on it. As a result, whenever an update is available, make sure to install it in order to stay up to date with the most recent software.

If you are using Bluetooth PC speakers and you are running an older version of Windows, you will notice buzzing in the speakers. The good news is that you can troubleshoot the problem to figure out how to resolve it on your computer.

If you have speakers that are controlled by an app on your mobile device, you will need to update the app on a regular basis when it asks you to do so. This is possible with Bose or other high-end speakers, where the app plays a significant role in how well they perform.

The Quality of the Audio Cable

Due to the increasing popularity of Bluetooth modules and smart assistants, it has become necessary to connect these devices to speakers. In order for this to be possible, a short wired connection between the speaker and the smart assistant is required. In most cases, a stereo headphone jack or a 3.5 mm cable is used to connect the headphones.

As a first step in troubleshooting the cause of the buzzing in your Bluetooth speaker, try swapping out the audio cable with another to see if the one you were using was the problem. Test the audio device by disabling and re-enabling it, as well as playing any audio to see if the static noise issue has been resolved. If the buzzing stops, it is likely that the audio cable was the source of the problem all along.

Music App that is out of date

If you are playing your music through an application on your audio device, the application should be updated to the most recent version. It is possible that using an outdated music app on your phone or computer will have an adverse effect on the sound quality of your speakers.

Delete the music app and reinstall it if you continue to hear a buzzing sound coming from your speakers after updating the music app. However, deleting the app may result in the loss of any albums, downloaded songs, or playlists that were created. It is possible that re-installation will take some time, which can be an inconvenience.

Thanks to the fact that many apps nowadays have accounts that store information in the cloud, recovering information is much simpler.

Music apps, like any other software, are developed with lines of code, which, if they are interrupted, can have an adverse effect on the sound quality of the app. It is possible to erase and rewrite affected lines of code on your device by deleting and reinstalling the application.

Bluetooth Speakers that aren’t working properly

After exhausting all other possibilities for the source of static noise in your speaker, you may be disappointed to discover that your Bluetooth speaker is essentially faulty. If everything on this list is in perfect working order, this is a possibility as a possible explanation.

Bluetooth speakers, like any other electronic device, are susceptible to malfunction. These speakers have receivers that, despite the fact that they are designed to be durable, can be damaged as a result of normal wear and tear.

When attempting to determine whether your speakers are faulty, connect your device to a different speaker and see if it works. If it does, you will have determined that your speakers are faulty. However, if the second speaker also experiences the same issue, it is possible that the signal is the source of the problem.

Repairing a damaged Bluetooth receiver is the most effective method of resolving the problem.

Bonus Suggestions

With all of these possible causes of buzzing in your speakers, it’s easy to overlook even the most straightforward solutions, such as re-pair. It is possible that re-pairing your Bluetooth speaker with your devices will eliminate the static noises. 

Suppose the first connection had a problem, in which case re-pairing might be necessary to correct the connection problem. Re-pairing can be accomplished with relative ease through the settings menu on your mobile phone, laptop, or tablet.

Another bonus tip is to look up the support website for the specific manufacturer you’re working with. While you may believe that your buzzing speaker is an isolated incident, contacting your speaker’s manufacturer’s support site may provide you with valuable insight into what to do in the event of a repeat occurrence.

If your speaker is made by a well-known brand, you should be able to easily obtain a troubleshooting manual to resolve your crackling sound problems.

Alternately, you can check the audio settings on your computer. Your Bluetooth speakers may buzz if the audio settings are not correct on your device. This noise may be eliminated if the system is configured properly. Go to your computer’s “Control Panel” and select “Hardware and Sound” from the drop-down menu.

Select “Sound” from the drop-down menu, and then “Properties” from the pop-up pane that appears. After that, go to the “Enhancements” tab and uncheck the “Disable all sound effects” box, then click “Apply” and “OK.” Once that is done, you can move on to the next step. Make another attempt with the speaker and pay attention to the sound quality.
