THERE’S A DELAY BETWEEN WHAT YOU SEE AND HEAR?

Bluetooth is not an instant transmission protocol and there are some lag / delay due to the time it takes for the signals to be encoded and transmitted. Typically if you're listening to music or audio only, you won't ever notice this lag.

However, pair audio with video or use Bluetooth devices with musical instruments where the user expects instant feedback and it is noticeable.

In general, the lag should be between 0.2 to 0.5 seconds. But there are some factors that can increase the amount of lag / delay you experienced.

 

  • Signal interference from nearby wireless transmissions. Things gets really bad if you are near a radio broadcasting device.
  • Other Bluetooth signals within range. Not so bad, just a little more delay.
  • Obstacles in the transmission path. This makes the sounds cuts in and out all the time.
  • Defective internal circuits.
  • Yes, defective internal circuits can also cause excessive amount of lag. So if you experience more than 1 or 2 seconds of lag for no obvious reason, please contact us and let us know.
