Fix Bluetooth Audio Delay: Have you ever used Bluetooth earphones to watch a movie, and the audio lags as the video plays ahead? It is among the most grating sensations. Quality Bluetooth headphones are costly, so it’s annoying to have an issue after spending so much on them. Fortunately, most Bluetooth audio lag issues may be fixed by updating, tweaking, or setting the settings on Windows, Mac, or mobile devices. We offer a list of solutions for audio delay issues. Use these techniques up until the audio syncs perfectly.
How To Easily Fix Bluetooth Audio Delay?
It’s challenging to isolate a single common cause for the audio delay. However, below is the list of potential causes for the audio delay with Bluetooth devices.
1 – Obstacles between a Bluetooth device and a receiver device.
2 – Bluetooth signal interference from other wireless signals using the same frequency. Check for routers, Bluetooth devices, and other wireless transmitters.
3 – The separation between the Bluetooth device and the receiver.
4 – The difference in audio coding between the transmitter and the receiver. An audio codec is a system for transferring audio data from transmitter to receiver. Each brand uses a certain codec. Incompatible codecs may cause audio lag issues.
5 – The difference in Bluetooth Standard. A rollback system is used in Bluetooth technology, which has a current Standard of 5.2.
For instance, if the transmitter has Bluetooth 5.0 and the receiver has Bluetooth 4.0, the data transfer will be by the 4.0 options. Always remember that the audio latency problem is worse with earlier versions.
Before Moving On To Fixes, Some General Considerations
1 – We recommend following the general fixes listed below before moving on to any of the fixes below:
2 – Check if the batteries in both devices are enough. An issue with the audio might result from low power in the transmitter and receiver.
3 – Verify that the two devices are within range of one another. They must be close together for the Bluetooth system to function. The higher two devices are to one another, the more likely audio issues will occur. The Bluetooth device’s user manual or a simple Google search using the device model number may be used to check the suggested range.
4 – Reboot/ Restart devices and check whether the audio delay has disappeared. Continue to the fixes below if the issue is still occurring.
5 – Check whether the audio issues only happen sometimes or when using particular apps like Edge, Chrome, Media Player, or other third-party music apps. We advise upgrading these apps if it only occurs when you use them. In the worst situation, you might need to find a replacement if the issue affects that one app. Again, this holds for both smartphones and PCs.
6 – Reset your Bluetooth device completely. After holding down the power button for 5–10 seconds, most Bluetooth earphone devices reset. Some speakers require a power button and many volume controls. For this procedure, go to the device’s user manual or use the brand and model number to search for instructions online.
7 – Make that the device’s operating system is up to date, especially if it is a smartphone. New upgrades now fix any formerly discovered OS problems. A manufacturer’s OS update might provide the solution if a system fix was to blame for the audio issues.

In Developer Options, Change Codec Settings
1 – Navigate to the settings on your device and find a section titled “About Phone,” “About Device,” etc.
2 – Repeatedly choose the OS version seven times. Depending on the brand, the number of times may differ. The device will indicate how many selections are necessary after the first one to reach the developer option.
3 – Return to Settings and locate Additional Settings when the developer mode has been enabled. The Developer option may be found and chosen.
4 – You will find a section only for Bluetooth settings under the developer option. Look for and choose the Bluetooth Audio Codec option.
5 – Select the audio codec from the Bluetooth device’s user manual, or search online for the brand and model of the audio codec. Brands use various codecs.
Apple employs AAC, Sony uses LDAC, etc., as examples.
Remember to check the receiver device’s supported Codec formats.
6 – There are more Bluetooth options in the developer’s mode. Try experimenting with other settings, such as the Audio Sample Rate, Audio Bit per sample, or other settings shown in the image below, to see whether audio latency changes.
Keep the settings if the issue is fixed; if not, return to the defaults. Keep in mind that higher sample rates can minimize latency but will also put more strain on the CPU.
Warning: Don’t change any further Developer options settings. Mistakes in the Developer option may result in your phone not functioning.
Change The Performance Mode
The settings menu on most Android devices will include a performance mode option. The details will differ from phone to phone. Find yours, set it to high performance, and check whether the issue still exists. Usually, the battery section of the settings is where you’ll find it. Brands might make a difference in how it is. These settings are absent from some devices.
Remember that the battery life and process will be under more stress when the device enters a high-performance mode. Whether it doesn’t, check back to balanced and see if the audio issue improves. Be aware that a high-performance mode might quickly deplete your battery on the phone with poor specs and, in rare situations, result in a heating issue.
How Should We Use An iPhone?
Since iPhones don’t have developer options like Android devices, you can’t do anything with them. The only thing you can do is follow the broad steps outlined above. The best action section is disconnecting and reconnecting the device via Bluetooth. Before connecting, make sure you click the device options to forget them. Sincerity is damned; only Apple might be able to fix these Bluetooth audio delay issues. As each Apple device is designed to be interoperable with other Apple devices, we recommend using Apple ecosystem devices.
Technology like Bluetooth is ever-evolving. We have yet to fully transition to a latency-free period since the process requires encoding, transmission from one end, and decoding. The best we can do is to use the appropriate codecs, ensure that our devices are current, check that our device settings don’t make too latency, and use Bluetooth devices from reputable brands. If you choose to use Bluetooth headphones for gaming, we still recommend against doing so.
