Sleeping, concentrating or preserving oneself from the surrounding noise is not always easy. Since 1918, authentic Quies wax balls have won over generations of people who aspire to calm. They protect the ears from noise by reducing noise by an average of 27 dB. Surrounding conversations or deafening sounds are greatly attenuated to preserve your hearing capital… and your serenity! Made of natural wax, these malleable hearing protectors easily adapt to the shape of the ear canal. Hypoallergenic, they adopt body temperature and slightly lubricate the ear canal to make you forget better. Ideal for prolonged use!
