 Frequently Asked QuestionsDo you have questions about QEOS hearing protectors?

Flat attenuation filters reduce noise evenly across all frequencies, preserving sound quality while reducing volume, making it easier to hear colleagues or machinery at a lower volume. HFA (High Frequency Attenuation) filters, however, reduce high-pitched sounds more effectively and are ideal for environments with extremely loud, high-frequency noises (grinders, plane engines, etc.). Sounds may be slightly altered, as users will hear lower frequencies more clearly.

QEOS hearing protectors are covered by a 6-year warranty. The Effi-6 guarantee ensures a new pair of QEOS earplugs in case of material, comfort, or attenuation issues if the noise reduction measured by the CAPA© system does not meet standards.

Yes, QEOS is a certified Individual Noise Protection Device (INPD) under the EN 352-2:2020 standard (PPE against noise).

With QEOS, maintenance is simple and quick. The filters do not require specific maintenance. Using wipes and cleaning foam on the outer surface enhances comfort and ensures the earplugs are worn 100% of the time in noisy environments.
For more details on cleaning products, please refer to the user guide provided with your QEOS hearing protectors.

QEOS custom-molded earplugs are water and dust-resistant. However, they are not submersible and should not be immersed in any liquid cleaner.
