Why use earplugs? The United States Environmental Protection Agency and WHO recommend that the average noise level of 24 hours per day should be below 70 decibels, and generally it will not affect the hearing. Gershon said, in addition to hearing damage, excessive noise is also associated with hypertension, heart disease, endocrine disorders, sleep disorders, and even affect children's learning ability. NOTICE Please keep the earplugs dry and clean Washing hands before use and the earplugs should be replaced or cleaned in time The use of earplugs may cause earwax to be pushed into the middle ear when the earplug is inserted into the ear canal, which can cause tinnitus, reduce hearing, pain or bacterial infection. Users with excessive earwax should be more careful to use earplugs, and earplugs should be washed with water and mild soap, but they may lose slow rebound after soaking in water How to use properly Please rub the earplugs first and insert them into the desired ideal position. Gently press the earplug for 30 seconds until the earplug is fully expanded and finalized. When earplugs are completely inflated, it's better not to push them in.
