This article will show you how to fix soundcore P30i/R50i NC's noise cancellation has no effect or does not work.

Firstly, please open the app to confirm if the earbuds are in noise cancellation mode. When removing or placing the earbuds, if you accidentally touch the earbuds' logo area, there is a chance that the earbuds will switch to ambient sound mode, and you may not be in noise cancellation mode when wearing the earbuds.

If your earbuds are already on the ANC mode, to fix the problem, please try the following as they have proven to be helpful.

1. Manually adjust the ANC to 5.

2.  Try other sizes of ear tips to ensure the ones you're using fit well and create a tight seaI. If one earbud feels stable and the other does not, try a combination of ear tips such as medium on the left and large on the right.

3. To check if you're wearing the earbuds in the perfect position, take the Fit Test on the soundcore app for more information. If the earbuds are not worn properly in your ears, you may not get the best noise cancellation.

4. Test the earbuds in a different environment and with a different Bluetooth device to see if that makes any difference.

Note: In a noisy environment and at high volume, you may feel that the noise cancellation performance is not as strong.
