Don't worry! Your Audioengine product is most likely not the problem. Audioengine Bluetooth products are designed to have very low latency (<30ms).
It's important to know that your source device has an impact on latency as well. Issues with the sound being out of sync can sometimes happen when your source's software is not up-to-date; so, be sure to update your source's operating system (OS) if an update is available. Rebooting your source and speakers can help correct issues with sound delay as well.
