Usually, you won’t notice the audio delay if you’re listening to music or podcasts.

How Bluetooth headphones work

To understand why your Bluetooth headphone has a delay, we need to understand the structure and how Bluetooth headphones work. 

In wireless headphones, including receiver – transmit signal, they can listen or receive commands from the server.

The higher the sound quality, the clearer and more accessible it is to hear the transmitted or received sound. 

However, wireless headphones can only bear a specific file size. If the Bluetooth audio file is too large, the headset will not be able to or take longer to process. It is one of the leading causes of sound delay.

Bluetooth Headphones Have a Delay phenomenon; what does this mean?

Sound delay is a phenomenon where sound and picture do not match. You can understand that the image is already displayed, but you are still not seeing the scene’s sound.

This phenomenon may relate to an error from the side of the video you are watching. You can disconnect the headset to see if it is still out of shape.

Pictures and sound are normal when not using headphones, and it’s time to recheck your Bluetooth headphones. There may have been an audio lag with the Bluetooth windows audio endpoint builder or connection line.

It is also challenging to avoid repetition if you know how to fix sound delay errors without knowing the phenomenon’s cause.

So, it would help if you learned the factors that affect the sound quality to prevent it from happening. Here are three main reasons affecting good quality.

Distance between two Bluetooth devices

Depending on the version of your headset and Bluetooth device, the safe connection distance will be different.

The higher version your machine is, the greater the connectivity it allows. However, connectivity is only available within a certain distance.

If you go beyond this distance, the connection will be affected. Specifically, the farther away, the weaker the transmission, the sound quality will gradually decrease until the connection is completely disconnected.

Distance will also include obstructions. If the distance is close, but there are many obstacles, the connection will also be limited. So you need to observe, ensure the appropriate length and space for the link.

Bluetooth audio settings

Everything will work smoothly when at its best version. You need to check and update Bluetooth audio to the latest version to prevent the connection. You also need to check the headset to make sure that the two devices are compatible.

Frequency noise

You probably have more than one wireless device in your home. It is possible to list a few typical examples such as wifi, wireless mouse, laptop, television. Each of these devices will operate on a different waveform.

Usually, these frequencies will work properly. Sometimes there will be some frequency conversion that occurs and overlaps with other devices. This phenomenon will cause noise, sound distortion, and even sound delay.

Using wireless headphones has become a habit of many people because of convenience. However, using Bluetooth audio headphones requires you to use a virtual connection with windows audio service.

You won’t be able to see this connection, so it will be hard to fix it. So, in addition to the above ways, you can try some tips to fix Bluetooth Audio Delay.

Make sure the device has enough battery

Your phone will become weak and disable some functions when it nears low power. Then some parts in the machine will not connect to devices such as cameras and games.

You will not be able to connect the headset via Bluetooth, or the connection will be intermittent when the device is almost out of battery.

So always make sure you have enough battery life when you are about to connect the headset. It is best to charge it again before joining for further use.

Do not place the source and the headset too far apart

Wireless headphones have made many people mistakenly think that they are not tied. Basically, Bluetooth can only connect within a specific allowed range. So if you leave the device fixed and move around like cleaning, the sound will flicker or lose connection.

The solution to this is to take your phone with you. Bringing your phone not only helps you to stay connected and can transfer songs quickly if you want.

Set the phone to high-performance mode

Young people today often install a battery-saving mode for the device to use the device for a longer time. Inadvertently, this limits the connectivity of the device. In some cases, it happens to connect only when you are active on your phone or only connect for a short time.

To fix this problem, switch to regular or high-performance mode. The increased performance will help your sound quality, transmission be better and not be interrupted when used.

Do not place two devices of the same frequency near each other

The wireless signal is annoying because you can’t handle it; it can’t debug or find a plug like a power cord. Two wireless devices close to each other quickly lead to the situation of catching the same frequency.

This phenomenon will cause a noisy, annoying sound. So you should tune two devices operating at two different frequencies. And it’s best to keep the two devices away from each other.


Bluetooth headphones are a new step forward in modern technology. However, this product has not been released long enough for engineers to completely fix Bluetooth headphones’ errors. 

So if you still want to continue using Bluetooth audio headphones, you should learn to live with those errors.
