This is a common issue with Bluetooth earbuds. In most cases, this delay is minimal and should not impact your experience. Factors that can influence it include the earbuds themselves, the connected device, the audio source, the app you’re using, and sometimes network conditions.

To fix this issue:

1. Forget the earbuds in your device's Bluetooth history and restart your device.

2. Fully charge your earbuds and reset them by following these steps:

- Place the earbuds in the charging case and ensure the case lid stays open.

- Press and hold the button on the back of the charging case for 10 seconds. Hold until the LED indicator on the case flashes white rapidly three times. This confirms the reset was successful.

Note: When resetting, the earbuds must be properly connected to the charging case. Please check that the left LED on the charging case lights up white when the left earbud is placed inside, and that the right LED lights up white when the right earbud is placed inside. This confirms that both earbuds are making proper contact with the charging case.

3. Test your earbuds with different Bluetooth devices, apps, and downloaded music/videos to see if the issue persists.

4. Turn off Dual Connections in the soundcore app.

Ensure the Bluetooth device and earbuds are within the Bluetooth range and free from signal interference.
