A damper of the positive kind. With the Bayer 04 earmuffs you defend the sensitive ears of our young fans. The earmuffs are adjustable, padded and suitable for children from 4 years. The external noise level is reduced by 24.3 dB with the help of the earmuffs. Of course, the earmuffs adorn the Bayer 04 logo. This makes them an absolute eye-catcher.
