How to Fix Sound Delay on Bluetooth Headphones

What Is Sound Delay on Headphones?

A sound delay is a discrepancy between when you hear a sound and when it is made. This can happen with any type of headphones, not just Bluetooth. 

When there is a sound delay, the audio from your phone or other device is not syncing up with what you see on the screen.

This can be highly frustrating, especially if you are trying to watch a movie or tv show without interruptions.


Why Does a Sound Delay Happen on Headphones?

To fix Bluetooth sound delay, you should know about audio latency first. Audio latency is the time it takes for a sound to travel from the source to your ears.

The speed of sound is about 343 meters per second. So, if you are listening to music on your phone that is 1 meter away from your Bluetooth headphones, it would take about three milliseconds for the sound to reach your ears.

However, most Bluetooth headphones have a latency of around 100-200 milliseconds. This means a delay between when the sound is made and when you hear it.

There are a few reasons why this happens:

1. Bluetooth uses a different type of coding:

Bluetooth uses a type of coding called SBC (Low Complexity Subband Coding). This is different from the kind of coding used in wired headphones, called PCM (Pulse Code Modulation).

The process work like this:

The audio is first converted into a digital signal. This digital signal is then compressed using SBC. The compressed signal is then sent to the headphones. The headphones decompress the signal and play the sound.

2. Bluetooth has to compress the data:

To save battery power, Bluetooth headphones compress the data sent to them. This can cause a delay in the sound.

3. The processor in Bluetooth headphones is not as fast:

The processor in Bluetooth headphones is not as fast as the processor in wired headphones. This means that it takes longer for the sound to be processed and sent to your ears.

4. Bluetooth audio chain:

The Bluetooth audio chain is the audio path from your phone to your ears. The longer the chain, the more likely there will be a delay in the sound.

The process work like this:

Your phone encodes the audio into a format that can be sent over Bluetooth. Then, it sends the signal to the Bluetooth transmitter.

The transmitter converts the signal into a radio wave and sends it to the Bluetooth receiver. The receiver converts the radio wave back into an electrical signal and sends it to the amplifier.

The amplifier increases the strength of the signal and sends it to the speakers. The speakers convert the electrical signal into sound waves that you can hear.

5. Audio file size:

The size of an audio file can significantly impact sound quality. Large files take longer to process and send to your ears, resulting in a delay that can be disruptive to the listening experience.

In addition, large files are more likely to suffer from data loss during compression, leading to reduced sound quality.

It is important to choose an appropriate file size for the content you are trying to listen to. If you are only interested in casual listening, smaller file size may be sufficient.

6. Interference:

Interference from other devices can also cause a delay in the sound. This is because the signal has to compete with other signals to be heard.

The single can be your wifi router, microwave, or even another Bluetooth device.

7. Distance between the source and the headphones:

The further the distance between the source and the headphones, the longer it will take for the sound to reach your ears.

This is because the signal has to travel through the air from the source to your ears. The signal travels at the speed of light, about 300 million meters per second.

8. Bluetooth version:

The Bluetooth version can also affect the sound quality and cause a delay. Because your device and headphones Bluetooth version has to match for the connection to work.

Not every Bluetooth version is backward-compatible. For example, if your phone has Bluetooth 5.0 and your headphones have Bluetooth 4.2, they will not be able to connect.

How to Choose the Best Bluetooth Headphones to Avoid Audio Delay?

When choosing Bluetooth headphones, you need to consider the following factors:

1. Choosing the correct audio codec:

When choosing Bluetooth headphones, you need to consider the audio codec. The audio codec is responsible for encoding and decoding audio signals.

Several different codecs are available, but not all of them are created equal. Some codecs are better than others at handling audio delay.

The aptX codec is one of the best codecs for handling audio delay. This codec is designed specifically for audio, and it can help reduce the audio delay by up to 30%.

The aptX HD codec is an even better codec for handling audio delay. This codec can help to reduce the audio delay by up to 50%.

The LDAC codec is also a good codec for handling audio delay. This codec can help to reduce the audio delay by up to 60%.

2. Frequency response:

Another important factor to consider is the frequency response of the headphones. The frequency response is the range of frequencies that the headphones can reproduce.

A wider frequency response means that the headphones can handle more bass and treble, which can help to reduce audio delay.

3. Look for aptX:

When shopping for Bluetooth headphones, look for a pair that supports the aptX codec. This codec is designed specifically for audio, and it can help reduce audio delay.

4. Look for headphones with low latency:

Some Bluetooth headphones are designed specifically for low latency. These headphones can help to reduce the audio delay by using a special antenna that transmits the signal more quickly.

A good pair of Bluetooth headphones will have a latency of around 40 milliseconds or less.

5. Bluetooth audio profile:

The Bluetooth audio profile is the specification that determines how Bluetooth audio is transmitted. The A2DP profile is the most common audio profile, and it is designed for streaming audio.

The aptX codec is not supported by the A2DP profile, so if you want to use aptX, you will need to choose a different audio profile.

The aptX HD codec is supported by the A2DP profile, so if you’re going to use aptX HD, you will need to choose a different audio profile.

The A2DP profile does not support the LDAC codec, so if you want to use LDAC, you will need to choose a different audio profile.
