What can I do if the noise cancellation is not effective?

Buds Pro supports a variety of noise cancellation effects, with a maximum noise reduction of 45 dB. Download the Nothing X App. Open the app and check the ANC settings in Noise Control. The settings provide multiple options such as "High/Mid/Low". If ear caps are not worn properly, noise cancellation will not work well due to lack of tightness. There are different sizes of ear caps available for use with the earbuds. We recommend that you try again with different ear caps.
