To maintain the sound attenuation performance of the ear muffs, it is important to regularly replace cushions and inserts. Under normal use, replace the hygiene kit at least twice a year. If using in tough and dirty environments, the hygiene kit should be replaced more frequently. To avoid sound leakage, the hygiene kit must be replaced if cracks or any other damage of the cushions are detected.
