How To Fix Bluetooth Audio Delay?

Have you ever tried to put on a video with Bluetooth earphones, and the video starts playing ahead while the Audio lags? It is one of the most annoying feelings. I mean, quality Bluetooth headphones aren’t cheap and to face an issue after we paid so much is a pure annoyance.

Luckily most Bluetooth audio lag issues can be fixed with some updates, tweaks, and setting changes in Windows, Mac, or Mobile Phones. We have compiled a list of ways to take the audio delay issues. Try these methods till the audio syncs in perfect time.

How to Fix Bluetooth Audio Delay?

It’s hard to pinpoint one universal reason for the audio delay. Check out the list below for possible reasons why Bluetooth Devices face audio delay problems.

Check out the list below for possible reasons why Bluetooth Devices face audio delay problems.

  • Obstructions between Bluetooth & Receiver Device
  • Interference in the Bluetooth Signal by other wireless signals in the same frequency. Be aware of other Bluetooth devices, routers, or devices that send out wireless signals.
  • Distance between the Bluetooth & receiver device.
  • The difference in Audio Codec between transmitter and receiver. Audio Codec is a system to transfer audio data from transmitter to receiver. Each brand has a certain codec they use. Incompatible codec may cause audio lag issues.
  • The difference in Bluetooth Standard. The current Standard of Bluetooth is 5.2. Bluetooth technology follows a rollback system.

E.g., If the transmitter has Bluetooth 5.0 and the receiver has 4.0 versions, the transfer of data will be according to the 4.0 options. Remember, the older the versions, the higher the audio latency problem.

General Things to Consider Before Moving on to Fixes

  • Before moving on to any of the fixes below, we recommend following the general fixes stated below:
  • Check if both devices have enough battery life. Low power in both receiver and transmitter might cause an audio issue. 
  • Confirm both devices are in the range of one another. The system of Bluetooth itself requires them to be in proximity. Further, the devices are to one another, higher the chances of audio issues. We can check recommended range in the Bluetooth device’s user manual or just google it using the device model number.
  • Reboot/ Restart both devices and see if the audio delay is gone. If the problem is still recurring, move on to the fixes below.
  • Check if the audio issues occur all the time or with specific applications like edge, chrome, media player, other third-party music apps, etc. If it’s only happening during the use of these applications, we recommend updating these apps. If the issue is isolated to that one app, you may have to find an alternative in the worst-case scenario. This is applicable for both PCs and Smartphones.
  • Hard reset your Bluetooth Device. Most Bluetooth earphone devices reset after pressing the power button for 5-10 seconds of the case. Some speakers need a power button with a combination of volume buttons. Follow the device’s user manual for this procedure or google instructions with the help of the brand and model number.
  • For Smartphones, make sure that the device is updated to the latest Operating system. New updates fix any previous bugs found in the OS. If a bug in the system caused the audio issues, the manufacturer’s OS update might contain the fix.

MacBook Specific Fixes to Try Out

Apple is more restrictive in its settings compared to windows. The following steps are the go-to steps for any problems with Bluetooth devices. These steps help keep the Mac settings favorable to better Bluetooth experiences. If mac settings cause the lag, it will likely be fixed with the following methods.

Debug Bluetooth Module

  1. If the Bluetooth icon is not in the menu bar, go to System preference and click on Bluetooth. Once a pop-up opens, tick the section at the bottom called “Show Bluetooth in the menu bar.”
  2. Once the icon is in the menu bar, hold down the Shift and Option key and click on the Bluetooth icon on the top right-hand corner of the screen.
  3. A drop-down will open. Choose the option Debug (newer Mac OS may not have Debug and will straight up list options).

Android Specific Fixes for Audio Delay

Please follow the above general tips before moving on with the fixes below. Also, the settings for android phones might differ according to the brands. But the gist of the process is the same. Read the following tips and try finding solutions to the Bluetooth issues.

Reset Bluetooth cache data

  1. Go to the Settings of your Android Device find/select an option called Apps or Apps Management. Select Manage apps from there.
  2. Once a list of apps emerges, try searching for the option Bluetooth and select it.
  3. You will see a Clear Data option, most likely on the bottom part of the screen.
  4. Select Clear All Data. Now Reconnect/pair the Bluetooth device with your phone.Bluetooth cache clean up

 Change Codec Settings in Developer options

  1. Go to your device’s settings and find a section called About Phone, About device, etc.
  2. Select on the OS version around seven times repeatedly. The no of times might differ according to brand. After the first selection, the device will tell you the number of times required to get to the developer option.MIUI version press to open developers options
  3. Once the developer mode is activated, go back to Settings and find Additional Settings. Find and select the option named Developer option.
  4. Under the developer option, you will find a section dedicated to only Bluetooth settings. Find and select an option called Bluetooth Audio Codec.
  5. Choose the Audio Codec listed in the user manual of the Bluetooth device or google the audio codec specification by brand and model. Brands adopt different codecs.

    E.g., Apple uses AAC, Sony uses LDAC, etc.Remember to check the Codec formats supported by the receiver device too.

  6. There are other options in developers mode that control other aspects of Bluetooth. Play around with different settings to see if audio latency changes like Audio Sample Rate, Audio Bit per sample, or other settings highlighted in the picture below.

    If the issue gets fixed, keep the settings else, restore it to defaults. Note that Higher Sample rates will reduce latency but put additional stress on the processor.developers settings in android

Warning: Do not touch any other settings in Developer options. Mistakes in the Developer option can completely stop your phone from working.

Try Changing the Performance Mode

Most Android devices will have a performance mode selection from the settings. It will differ from phone to phone. Try finding yours, set it to high performance, and see if the issue persists. It’s generally located in the battery section of the settings. It might be different according to brands. Some devices do not have these settings.

Remember, As the device goes into high performance, there will be additional stress of the process and battery life to maintain this stage. Check if the audio issue gets better in this mode if it doesn’t change it back to balanced.

Note if you have a low specification phone, a high-performance mode can drain the battery fast and can cause a heating issue in some cases.

What to do if we use an iPhone?

 You cannot do much for iPhones as they do not have developer options like the androids. The only thing you can do is follow the general steps stated above.

The best effort is to remove the device from the Bluetooth section and reconnect it again. Make sure you click on forget the device options before reconnecting.

In all honesty, Only Apple might be able to fix these issues. We recommend using devices of the Apple ecosystem as each apple device is catered to be compatible with Apple devices.


 Bluetooth is an evolving technology. As the process involves encoding, transmission from one end to decoding in the other., we haven’t reached a complete latency-free era.

The best we can do is use the right codecs, make sure devices are up to date, ensure our device settings don’t increase latency, and use good brands of Bluetooth devices.

We still recommend using wired headphones if you use Bluetooth headphones for gaming.
