CEARVOL support FAQ

Common questions about manuals, registration, and support for this brand.

  • How do I solve the whistling sound (feedback) in my CEARVOL hearing aids?

    Whistling usually indicates sound leakage. Ensure the earbud is inserted securely by using the 'twist to lock' method. You may also need to switch to a larger ear tip to create a better seal or lower the volume before insertion.

  • Does the CEARVOL Nano connect to smartphones via Bluetooth?

    No, the CEARVOL Nano is a standalone hearing aid designed for simplicity and does not support Bluetooth streaming or app connectivity. The Diamond X1 model, however, supports Bluetooth 5.3.

  • How do I toggle hearing environments on my device?

    For models like the Nano, press the dedicated mode button on the charging case or device. Voice prompts typically confirm the mode, such as 'Indoor', 'Restaurant', or 'Outdoor', which adjusts noise suppression accordingly.

  • My own voice sounds hollow or like I am in a tunnel. Is this normal?

    Yes, this is called the 'Occlusion Effect' and occurs when the ear canal is blocked. It typically fades as your brain adapts over 1-2 weeks. Trying a smaller ear tip can also help alleviate the pressure.

  • How do I charge my CEARVOL hearing aids?

    Place the earbuds into the charging case. Ensure the blue protective films are removed from the contacts and that the golden charging points are clean. The case usually provides multiple full charges for the earbuds.
