  • The sound quality of CMF Buds Pro 2 is not great. Is there anything I can do?

    The sound quality of CMF Buds Pro 2 is tuned based on extensive user experiences and is at a relatively high industry standard. However, individual preferences for sound quality may vary. We recommend downloading the Nothing X App and accessing the Equalizer page to choose preset sound effects. Additionally, you can customise the sound according to your personal preferences in the Custom settings.

  • I'm not happy with the noise cancellation effect. What can I do?

    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.

  • I'm not satisfied with the noise cancellation effect. What can I do?
    Please download the Nothing X App and access the ANC settings in the app's Noise Control section. Additionally, the effectiveness of noise cancellation is heavily influenced by how the earbuds are being worn. Incorrect positioning or ill-fitting ear tips can affect the airtight seal and, consequently, the noise cancellation performance. We recommend trying different ear tips and adjusting the fit to ensure a snug and leak-free seal for the best noise cancellation experience. If you have any other concerns, please contact our Customer Service.
  • Why does it take time for sound to play through my earbuds after they've connected to a device?
    Due to compatibility issues with Bluetooth Fast Pair and Dual Connection features of some device systems, there may be occasional delays in sound output when you switch music channels or try to connect your device. The issue may occur with TWS Bluetooth earbuds on the market. This is a normal phenomenon and does not indicate any abnormality with the earbuds. Please feel free to use them with confidence.
  • Why is there a sound output delay once the earbud is connected?

    Due to the compatibility of some Bluetooth connections, there will be a sound delay with certain devices.
