✅【40dB Soundproofing Effect】By wearing SijiRuge earplugs, you can reduce noise by approximately 40dB, reducing most noise and providing comfortable hearing protection over a long period. ❗Note: This is not complete soundproofing, so you can still hear necessary sounds like alarms and calls, allowing you to use them with peace of mind. ✅【Comfortable for Long-Term Wear】With an innovative ergonomic design, they gently fit the ear canal with almost no feeling of blockage, and your ears won't hurt even after wearing them for a long time. Earplugs come in three sizes (S, M, L), so you can find the size that suits you! ✅【Easy to Wear & Washable for Repeated Use】The earplugs are not distinguished between left and right ears, so they are easy to wear by gently pulling up your ear and inserting the earplug into the ear canal. They can be washed with water and reused if they get dirty. ✅【Wide Range of Uses】Very suitable for use at home, hotels, campsites, on airplanes, during sleep, work, study, meditation, and when you want to concentrate.
