Why Is There Sound Delay In Roku Wireless Headphones?

If you use wireless headphones in private listening mode with equipment from Roku, you have probably noticed that quite often the sound of the movie you hear does not match the picture on the screen a little. There is some audio delay.

The reason wireless headphones cause lag and skips is because they use a wireless mechanism called Bluetooth to make them wireless.

For example, wireless problems include interference with other Bluetooth devices and microwave ovens, and interference with radio waves due to obstructions. In addition, as a problem with the device, there are also reasons such as an outdated version of Bluetooth and incompatibility of the built-in codec.

How to reduce delays and gaps that occur in wireless headphones? While this is a specification issue, lags or skips are undesirable when using wireless headphones. If there is a delay while watching a movie or drama, the movements of the mouth and lines will not match.

Also, when playing games that move in real time, such as FPS (a 3D shooting game that develops from the perspective of the protagonist) and eSports, audio lag can lead to fatal errors.

Next, let’s imagine how to improve the latency and audio skipping that occurs in wireless headphones.

To eliminate delays and audio skipping that occur with wireless headphones, check your wireless environment first.

  • First, make sure there are no obstacles between the wireless headphones and the playback device. If you are in the same room, there is no problem, but if there is metal or concrete, radio waves are more likely to be reflected. Also, water blocks radio waves, so be careful if you have a large tank.
  • People whose bodies are said to be 70% water can also become obstacles, so if there is or is no delay, check the movements of your family members. Be sure that even the same obstacles like trees, glass and paper are okay.
  • Next, check for any objects that may interfere with the radio waves. In particular, keyboards and mice using Bluetooth may cause interference if placed near a playback device. Products such as microwave ovens and cordless phones are also susceptible to radio interference.
  • In addition, the distance between the wireless headphones and the playback device may be too large. The Bluetooth connection distance is a maximum of 10 meters, but you are unlikely to be more than 10 meters away indoors.

To improve latency and audio skipping experienced with wireless headphones, consider improving the software. First of all, regarding the improvement of the Bluetooth version, in order to minimize the risk of delays, it is better to use wireless headphones with version 5.0 or higher.

Also important is the codec method that converts the digital data into audio. For example, iPhone and iPad use the AAC method, and Android smartphones and tablets use the aptX method, so it is recommended that you use wireless headphones with a codec that supports the Roku device you are using.

Also, these enhancements are hardware specifications, so they cannot be changed later. So check the specifications of your wireless headphones and consider getting new ones that match your playback device.
