How To Fix Sound Delay On Bluetooth Headphones | A Quick Guide

One of the devices changing how people listen to music is the headphone. The innovative features of headphones open up a world of possibilities. But wireless connectivity is the most impressive and game-changing aspect that makes it even better. Which provided the consumer with freedom from wires. But sometimes to accomplish something, you have to make some compromises. 

How To Fix Sound Delay On Bluetooth Headphones

Occasionally, wireless headphones experience high latency meaning high sound delay, which can be incredibly annoying. Knowing how to fix sound delay on Bluetooth headphones can improve the quality of life. That is why we have prepared these guides that will guide you on how you can improve the sound delay issue on your wireless headphone.

Why sound delay happens in Wireless Headphones:

First to solve the problem we need to understand what happens in the first place.

The sound delay is when the audio is not synced with the video you are playing. This delay is commonly known as latency. High latency is more common in wireless devices as compared to a wired connection. The wired headphone has a latency of  5-10 milliseconds, which is when your device takes to process and send data, which is negligible. 

But in the case of Bluetooth connection, the latency ranges from 100-300 ms, and in the case of aptX LL support, it can be reduced to 35 milliseconds. But this is unnoticeable too so you can have low delay easily on a wireless Bluetooth headphone.

Bluetooth headphones experience a delay because of a couple of reasons and eliminating them will result in less delay. The 4 main reasons for the delay in your headphone can be

Bluetooth Version:

Let’s talk about Bluetooth itself. It is a wireless technology used by smartphones, tablets, and other devices to transfer data over short distances using radio waves. The latest version, 5.0, is quite superior to all other versions. So the version of the Bluetooth device and headphones can be the reason for the delay.

Codec:

By compressing, encoding, and decoding the audio signal, the algorithm reduces the file size to speed up the transfer. That algorithm is known as the Bluetooth codec, which can also contribute to the delay itself. Because the codec takes time to encode and decode, the more time it takes to do this step, the higher the delay there will be.

Interference:

As I mentioned above the Bluetooth technology uses radio waves to transfer the data. So there are many many sources of radio waves around us. The other wireless devices, Television, and even Wifi are responsible for emitting the radio waves. The waves from all the devices can easily interfere with the communication between the headphone and audio devices.

Distance:

The distance between the sender and the receiver is also one factor contributing to the audio delay. Although wireless technology has freed us from the wire by giving us a long-range than the wire, unfortunately, that range is also limited. Approximately 10m which could vary from the Bluetooth version. And the range is also affected by the physical blockage.

How to fix the sound delay:

An excessive delay or latency in the headphone can be annoying and you will want to reduce it. Delay is something that will always be to some level of delay and there might not be a way to completely remove it. It can, however, be reduced to the point that it is barely noticeable, and here are some ways to do so

Choose the latest Bluetooth version:

The first thing you should choose after the sound quality of the headphone is the latest. Although the newest version of Bluetooth is 5.2 which was introduced in January 2020 the most are the 5.0 is the latest that current headphones are featuring. So chose the headphone and device with the latest Bluetooth because if one is outdated it will continue to delay since it is way transmission

For example, its headphones have 4.0 Bluetooth, and the mobile uses 5.0. The headphones will deliver the data slow as compared to the mobile which will drag down the overall performance of audio down.

Choose Fast Codec:

Codec is another factor affecting the speed of the data transmission and the delay of the sound.

Transferring large data requires more time so the most efficient way is to reduce it to compress what codec does. When selecting the headphone choose the latest codec. The ideal choice should be aptX series which is fast to the degree that its aptX LL series can deduce delay to 35 milliseconds. Or you can select that work best for your devices like Samsung uses Samsung Scalable Codec is ideal for Samsung devices.

Update drivers:

If you have the latest Bluetooth and fast codec but still facing delay the issue might be in drivers. Sometimes old drivers held the headphone back. Manufacturers constantly update their drivers based on suggestions and feedback. 

If your drivers are out of date, follow these steps to update them on the Windows 10 system

  • Right-click the start icon, find the “Device Manager” option and left-click on it. 
  • Then expand the list by clicking the arrow in front of “Bluetooth” 
  • Right-click on the headphone name and select update
  • A tab will open click on the “Search automatically for divers”

Reduce the distance and interference:

Communication between divisions is affected by distance since Bluetooth uses radio waves; the distance will be directly proportional to delay because the signal deteriorates or takes more time to reach the receiver. Another factor whose reduction can lead to better latency is interference. If the number of devices around you that emit radio waves like WIFI, Television, radio, and other wireless devices in close space, turning them off or moving to a place where there is less interface can improve the delay issue.

Conclusion:

Delay in anything is frustrating so does the sound delay in Bluetooth headphones. To save you from that irritating moment we have suggested you some tips. Hopefully, that will be helpful.
