How To Fix Sound Delay On Bluetooth Headphones

Do you experience a sound delay on your Bluetooth headphones? Well, don’t worry as I’m here to help you! In this article, we will discuss how to fix sound delay on Bluetooth headphones.

Today, headphones have become a highly useful and indispensable tool in many people’s daily lives. Technology and science have changed in a way that makes wireless headphones more popular. It is a compact headset that you connect to a computer or phone via Bluetooth so that you can use it.

Sound delay is a common problem with Bluetooth headphones. In this case, the audio lags behind the video, creating an unpleasant experience. Many factors can contribute to this issue, such as distance, obstacles, and interference. 

Therefore, today we will show you how to fix sound delay on Bluetooth headphones in this article. Also, we will explain what factors affect Bluetooth sound quality. 

Without spending any more time in the intro, let’s get started!

What Factors Affect The Quality Of Bluetooth Sound?

There are various factors that can affect Bluetooth sound quality, including the following:

Bluetooth Version

When everything is at its best version, everything will work smoothly. To prevent the connection, check and update your Bluetooth audio to the latest version. It is also important that you check the headset to ensure that the two devices are compatible.

Over the years, Bluetooth technology has improved significantly. The latest Bluetooth 5.0 can process audio data more quickly than previous versions, resulting in shorter latency times and better sound quality.

Distance Between Two Bluetooth Devices

The safe connection distance varies depending on the Bluetooth headset and the Bluetooth device. If your device is a higher version, that allows for greater connectivity. But you are only able to connect within a certain range. 

Going beyond that range will adversely affect the connection. Furthermore, the further the distance, the weaker the transmission, the sound quality gradually decreases until the connection is lost completely.

Obstacles can also contribute to the distance. If there are many obstacles, the connection is also limited even if the distance is close. So make sure the length and space for the connection are appropriate. It is best to bring the headphones and audio source closer together.

Bluetooth Codec

A Bluetooth codec algorithm that compresses encodes and decodes digital audio data. In compression, it reduces the audio file size (so it won’t consume the bandwidth) and encodes it into an appropriate format to be transmitted. Then, it decodes the compressed data in order to convert it into an audio signal so that we can hear.

There are many Bluetooth audio codecs that are available, and each one comes with its own distinctive formula for the compression and transmission of audio data.

One of the most crucial things to bear in mind is that certain codecs are more effective than others in streaming music via Bluetooth. And you should use those codecs if you want to ensure a smooth music listening experience using Bluetooth headphones and your source.

Also, make sure that the Bluetooth codec of your headphones should match the codec of your audio source. Otherwise, they will simply use the lowest audio codec – SBC, which can also cause audio delay.

Interference (Frequency Noise)

An interference signal is a signal that interferes with the clear signal between your Bluetooth headphones and your source.  There are probably several wireless devices in your home such as wifi, wireless mouse, laptop, television. Each of them uses a different type of radio signal.

They emit radiofrequency that may interfere with the signal flow to your Bluetooth headphones. In most cases, these frequencies are effective. It is possible to have some frequency conversion that overlaps with other devices. If this occurs, noise, sound distortion, and even delay will result. 

How To Fix Sound Delay On Bluetooth Headphones

One thing that you need to remember is that audio delay will always be present in wireless connections. We’ve already explained that encoding, transmitting, and decoding audio data wirelessly always takes more time than wired connections. But you can minimize it so that it does not become too noticeable. 

Currently, there is no way to completely eliminate Bluetooth audio delay, but there are several things you can do to reduce the sound delay on Bluetooth headphones. Different operating systems use different software structures, so the connections and testing will be as well. 

Fixing Bluetooth Sound Delay Issue In Windows

The following are four ways through which one can resolve the issue of audio delay in windows PCs:

Reconnecting Bluetooth Headphones

Sometimes, this issue occurs due to a malfunctioning Bluetooth connection. In this case, the simplest solution is to reconnect the Bluetooth connection. 

Usually, this is the easiest and most common way to fix the problem. You may need to reset your Bluetooth headphones and speakers, then reconnect them to your computer after a few seconds. 

Simply disconnect the headphones from the device, turn it off, and then reconnect it with the power on.

Hopefully, it will correct the laggy connection and improve audio sync. If this doesn’t solve the issue, the next solution can definitely help.

Update The Latest Bluetooth Driver

When you connect your Bluetooth headphones for the first time, Windows automatically installs the appropriate driver. But it won’t automatically update the latest drivers until you manually update them. Sometimes headphones experience audio lag when using outdated software drivers.

To install and update the latest Bluetooth driver on your PC, follow these steps:

  • First of all, Right-click on the Start button (Windows logo), then choose Device Manager.

Why Do My Bluetooth Headphones Have a Delay?

Bluetooth headphones do not connect directly to your device since they are wireless. A Bluetooth connection is what allows them to connect with your device. Using wireless devices provides the benefit of free movement. But Bluetooth headphones have a delay because they have to transmit the audio signal wirelessly. This means that when listening to audio through Bluetooth headphones, there will be a delay between when you speak and when you hear your voice played back.

It is necessary for the devices to ‘sync up’ when there is a delay. To sync up, one device sends information, and the other must simultaneously receive it. This commonly happens when devices are close to each other. 

A large distance between the devices will result in a more noticeable delay. The Bluetooth connection can also experience sound delays if there is a lot of traffic. It becomes slower and more congested as more devices attempt to connect to the Bluetooth connection.

One way to reduce this latency is to enable the “audio codec support” setting on your Bluetooth device. This setting will allow your device to receive higher-quality audio signals, which will help to minimize the delay. 

You can try the above steps if your device is close to the other Bluetooth headphones, but they still have a delay. If none of these work, then you should contact your computer’s customer support team or the company that makes your headphones.
