CMF Buds Pro 2 supports active noise cancellation (ANC) up to 50dB. We recommend downloading the Nothing X app and checking the ANC settings under Noise Control. This setting offers multiple options such as "High," "Mid," "Low," and "Adaptive."
We also advise that improper fitting of the ear tips can affect the noise cancellation seal, resulting in poor or ineffective noise cancellation. The earbuds come with different sizes of ear tips. We suggest trying different ear tips to find the best fit for optimal noise cancellation.
For more precise adjustments and settings, please use the Nothing X app, available on Google Play and the iOS App Store.
