[Solution] Fix Bluetooth Audio Delay

Bluetooth connectivity-based headsets are now one of the most convenient, comfortable, and portable devices. From earbuds to speakers, most devices are now Bluetooth-based devices.

With Bluetooth devices, no one has to untangle the tangled loop wires. But do these Bluetooth headsets come up with all the perks? Well, no. In comparison to wired earphones, Bluetooth earphones fall short in a few areas, and one of them is Audio Delay.

Why is there a delay in your Bluetooth headsets?

Before answering why there is a delay in the audio connectivity to your Bluetooth headphones, let’s first try to understand What Does Audio Latency Mean?

All the audio hearing devices take some time to deliver the sound from the device source (say, Android, iPod, laptop, etc.) to the connecting device (say, speakers, headphones, earbuds, etc.) This time taken by the audio device to deliver the sound is mainly milliseconds.

This time taken to convert the digital data into an audio signal that could be accessed and streamed through a wired or wireless headset device is known as audio latency. 

Now, this audio latency is different across different devices. In a wired connection, this audio latency is 5-10ms. Whereas in a Bluetooth device, this audio latency ranges from 50-300ms. 

Now, if you wonder why wireless earphones take longer to transmit sound to you than wired headsets, then the simple reason is the sound transmission process in Bluetooth headsets.

In wireless Bluetooth devices, sound transmission happens between a transmitter and a receiver. The transmitter forwards the audio signals to the receiver. The bigger the audio size, the more latent it is. 

To check the latency of your wireless Bluetooth headphones, you can also look for Bluetooth latency tests. To perform this Bluetooth latency test, you can log in to different websites providing this test for free. 

Possible Factors Affecting Bluetooth Audio Delay:

There could be various reasons responsible for causing the audio delay in your Bluetooth headsets. Here we have listed down the four crucial causes that could affect sound delay.

• Bluetooth Codec
• Interference
• The distance between the source and the receiver
• Bluetooth Version

Discussing the factors affecting audio delay:

Bluetooth Codec –

A Bluetooth Codec is a vital algorithm that compresses, encodes, and decodes the sound data transmitted from the audio source to your headset. Although some Bluetooth codecs are better than others, some are terrible at their work. And the ones with this tribality are more prone to cause an audio latent.

To avoid audio delay due to the Bluetooth codec issue, one must check for the capability of the codec during purchase. It is essential to ensure that your device’s Bluetooth codec is compatible with your headset’s.

Interference –

Interference is the unwanted frequency that makes it harder for the transmitter to read the audio files. The other add-on frequencies of the electronic appliances in your room, like the microwave, heater, radio, etc. It might also disturb the transparent transmission of your desired audio.

The distance between the source and the receiver –

Though most wired headsets demand a certain distance to function well, wireless headsets don’t restrict you with the distance between the source and the receiver. Thus, many times, people face the sound delay issue due to improper connectivity and reach between the head and the receiver of the audio.

If you observe that the distance between your headset and the device is more than expected, you should try bringing them closer to fix the sound delay.

Bluetooth Version

Different headset devices come with different Bluetooth versions. Though the latest and updated version, the better it is. One must also keep in mind to find a version of the headset that is the latest yet compatible with your respective connecting devices.

How To Fix Sound Delay On Bluetooth Headphones

If the solutions mentioned previously did not work for you, it is possible that the issue lies with your headphones. It is important to note that features such as the Bluetooth audio codec cannot usually be altered or improved. In this case, the most effective solution would be to invest in a new set of headphones.

To prevent this issue from recurring, here are some factors you should take into account:

Method 1: Picking the right audio codec

To optimize your wireless listening experience, it’s important to match the ideal codec for Bluetooth streaming with your audio source. If you use iOS, headphones that support the AAC codec are recommended as it’s Apple’s preferred codec. For Android, aptX LL and aptX HD are the top choices.

Certain codecs are designed specifically for certain manufacturers, such as Sony’s LDAC and Samsung’s Scalable Codec. If you own a smartphone from one of these manufacturers, be sure to check your Android settings to see if the codec is enabled. Additionally, ensure that your Bluetooth headphones are compatible with the codec.

Method 2: Match the source and headphones’ Bluetooth audio profile

To improve audio latency, it’s recommended to use Bluetooth 5.0 for both the source and receiver devices. It’s important to ensure that the Bluetooth audio profile of the source matches that of the headphones. If both devices use Bluetooth 5.0, the connection will use this standard.

However, if one uses Bluetooth 4.1 and the other uses Bluetooth 5.0, the default connection will be Bluetooth 4.1. To take advantage of improved bandwidth and features, it’s best to use the latest Bluetooth 5.0 support for both the source and receiving device.

Conclusion:

It remains to be seen if sound delay will be completely eliminated with future advancements in BT technology. However, there’s no need to wait for that, as you can already reduce sound delay by following the information and tips provided here. With these techniques, you can enjoy watching videos and listening to music with your Bluetooth headphones without the frustration of sound delay.
