How to Fix Sound Delay on Bluetooth Headphones?

In either case, it is normal to have a sound delay between the source and the Bluetooth headphones. This is done for several very practical reasons. These common problems can be easily resolved. At the end of this article, you will get tips on how to fix this problem. Knowing the most common causes and how they occur can be important in understanding how to fix sound delay On Bluetooth headphones.

What is a Sound Delay in Bluetooth Headphones?

The sound delay in Bluetooth headphones occurs when the sound is out of sync. Even if you see what is happening, the tone of the actions will sound a little later. This delay is due to a number of issues that are discussed below.

Technically, this is known as Bluetooth audio delay and is a common occurrence with all types of Bluetooth audio devices, including your wireless headphones.

Common Causes of Sound Delays in Bluetooth Headphones

Due to the fact that Bluetooth is a wireless medium for audio transmission. And for logical reasons, the connection can become “weak”. A weak connection results in a delay in audio transmission (and in some cases this results in “dripping”, jerking, or jerking).

The most common causes of sound delays in Bluetooth headphones are:


The distance between the transmitter or source and the receiver has a direct effect on the quality of the Bluetooth connection. Every Bluetooth device has an “effective range” beyond which audio data cannot be sent to the source in a timely manner. 


Other wireless devices (including other infrared and Bluetooth devices) can cause interference, usually making noise, but can also cause sonic delays.

Codec Difference:

Bluetooth audio transmission works with codec-based compression and decompression. Data is essentially compressed using an algorithm determined by the codec used.

Typically, some codecs are better than others. It is known that certain Bluetooth codecs can cause compression interference under certain conditions. Poor compression and decompression can also cause audio delays.

Bluetooth Technologies:

Like any other data transmission technology, Bluetooth has grown over time. Bluetooth as technology is around 21 years old. The tenth version of Bluetooth, which is Bluetooth 5.0, is the latest and current wireless audio transmission.

It processes data faster than previous Bluetooth iterations and efficiently generates higher quality audio with shorter delay times.

However, Bluetooth 5.0 does not completely mask the latency of wireless audio. Instead, the delay is compensated for by a technique called audio-video synchronization (or A / V synchronization).

Each new version extends the effective range and mainly the transmission speeds.

As a result, older versions of Bluetooth can be very inefficient with modern devices in terms of range, transmission speed, or general reliability.

The Audio Quality and Size:

The larger and better the source audio file, the more bandwidth the audio signal needs for transmission. Due to bandwidth limitations, Bluetooth headphones may experience a delay when playing files that require more bandwidth than usual. Higher quality files like FLAC music or larger music files (in terms of the space they use) will both affect this.

Tips on How to Fix Sound Delay on Bluetooth Headphones

Repair your Bluetooth System

The best way is perhaps the most obvious. Restore the headphones and speakers, and after a few seconds, try connecting them to your computer. The offset is likely to decrease as data is recorded and items are not saved by the device. Even if it’s a minute or a drastic improvement, the delay will certainly decrease.

Bluetooth Driver

Like other types of connections, Bluetooth works with drivers on both ends. You must have a copy of the latest Bluetooth drivers so the connection can be strengthened.

However, if you do this manually, you are most likely dealing with outdated software drivers.

In some situations, outdated driver software can cause audio delays in Bluetooth headsets.

Follow the steps below to update the driver version of your Bluetooth headphones:

  • Search for “Device Manager” in the Start menu.
  • Then click and select “Bluetooth”.
  • A list of all Bluetooth devices connected to your system is displayed.
  • Find the name of your Bluetooth headphones and right-click on them.
  • Then select the “Update Driver” option.
  • Now select the option “Search automatically to troubleshoot Windows audio playback

Windows 10 has an advanced troubleshooting feature to fix basic computer errors. To reestablish a delayed Bluetooth connection using this feature, do the following:

  • Right-click the Speakers button in the lower right corner of your system tray. Choose Fix Sound Problems.
  • A list of audio devices is displayed. Select the one you are having trouble with and click next.
  • Windows will automatically diagnose any problem and automatically suggest the best solution.

Restart Windows Audio Service

Restart the Windows audio service. This is a constantly running background task to handle all audio playback and output on your computer. To restart it, do the following:

  • Press the Windows key and the R key at the same time.
  • Enter the services. MSc and press Enter.
  • Click on the “Windows Audio”
  • Right-click on it and choose Properties.
  • On the “General” tab, select “Automatic” as the start type.
  • Click the Recovery tab.
  • From the First Failure and Second Failure drop-down lists, select Restart Service. Click OK.

Restart Your System and Plug Your Headphones Back In

If none of the solutions work for you, it might be a good idea to check the latency listed on your headphones box. It may not be the settings that are causing the problem, but your headphones may have high latency by default. In this case, you may want to change your headphones.


Bluetooth technology is advancing rapidly. We have reached the point where Bluetooth headphones and speakers are a more convenient hearing solution than their wired alternatives, at least for most people.

The only big sticking point seems to be the latency. While most issues with Bluetooth 5.0 and A / V sync will be fixed, players and musicians should pay special attention to the codecs supported by their devices.
