How to Fix Sound Delay in Bluetooth Headphones (Solved)

Have you ever seen a movie and wondered why a character’s voice and lip movements don’t match? This issue is commonly caused by “Bluetooth audio lag,” and can ruin your movie experience. 

Fortunately, you can fix this sound delay and get your Bluetooth headphone working again. Let’s find out in this article!

Why does my Bluetooth headphone sound delay?

Sound delay in Bluetooth headphones occurs when there isn’t enough bandwidth to support the audio file size moving from your smartphone, computer, or MP3 player to your headphone. 

To help you understand this better, suppose you attend an event, and there are tons of people trying to get into the venue through a small entrance at the same time. The movement will be slow, uncomfortable, and take longer.

You can liken the bandwidth of your connection to the narrow entrance and the volume of people to the audio size on your device. And there’s only one outcome, delay!

The audio signal transfer will be retarded if there isn’t enough bandwidth to accommodate a large audio file transmission, and this will cause an audio stutter and Bluetooth headphone lag.

How to fix sound delay on smartphones

Sound delays on Bluetooth headphones often happen when watching videos on your smartphone. Thankfully, there are several ways to fix this issue on both Android and iOS. 

Here’s how to fix sound delay in Bluetooth headphones when using your headphones with your smartphone.
