Why is there a delay in your Bluetooth headsets – The Science

Before answering why there is a delay in the audio connectivity to your Bluetooth headphones, let’s first try to understand what audio latency is?

Though if you are not interested in knowing this phenomenon of the cause of the delay specifically in the wireless or Bluetooth headsets.

Then you might consider to skip to the next part of the blog, I.e., steps to fix Bluetooth audio delay across different devices.

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 some millisecond.

And 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 a longer time to transmit the sound to you than wired headsets, then the simple reason is the sound transmission process in Bluetooth headsets.

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

  1. Bluetooth Codec – A Bluetooth Codec is an important algorithm that compresses, encodes, and decodes the sound data being transmitted from the audio source to your headset. Although some Bluetooth codecs are better than others, some are really terrible at their work. And the ones with this tribality are more prone to cause an audio latent. To avoid the audio delay due to the Bluetooth codec issue, one must check for the capability of the codec during purchase. It is important to make sure that the Bluetooth codec of your device is compatible with the Bluetooth codec of your headset.
  2. Interference – The 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 clear transmission of your desired audio.
  3. The distance between the source and the receiver – Now though most of the wired headsets demand to be at a certain distance to function well, the wireless headsets don’t restrict you with the distance between the source and the receiver. And thus, many at times, people face the sound delay issue due to the improper connectivity and distance between the source and the receiver of the audio. If you observe that the distance between your headset and the device is more than the expected one, then you should try bringing them closer to fix the sound delay.
  4. Bluetooth Version – Different headset devices come with different Bluetooth versions. Though the latest and updated version, the better it is. While one must also keep in mind to find a version of the headset that is latest yet compatible with your respective connecting devices.
