Ear Plugs are designed to bring you a quieter and more comfortable environment by reducing the impact of unwanted noise. Their purpose is to protect your hearing and provide a comfortable sound experience, rather than completely canceling all sound. Under normal circumstances, these earplugs can effectively reduce noise by over 30dB. However, in situations such as shooting at a range, stronger hearing protection may be needed. The earplugs are 100% reusable and washable. You can clean them with soap and warm water or external alcohol. It is recommended to clean them once a week to maintain their effectiveness.
