Thank you for viewing! Opened for photography, but it's a new, unused item. 【40dB Soundproofing Effect】 By wearing these earplugs, you can reduce noise by approximately 40dB, reducing most noise and providing comfortable hearing protection over a long period. Note: These are not completely soundproof; you can still hear necessary sounds like alarms and calls, so you can use them with peace of mind. 【Comfortable for Long-Term Wear】 With an innovative ergonomic design, they fit gently in the ear canal with minimal feeling of blockage, and your ears won't hurt even after wearing them for a long time. There are three sizes of earplugs (S, M, L), so you can find the size that suits you best! 【Easy to Wear & Reusable After Washing】 The earplugs are not distinguished for left and right ears, so they are easy to wear; simply gently pull up your ear and insert the earplug into the ear canal. You can wash them with water and reuse them. 【Wide Range of Uses】 Very suitable for use at home, hotels, campsites, on airplanes, during sleep, work, study, meditation, etc., when you want to concentrate. Recommended for those who want to improve sleep quality, and those with hyperacusis or misophonia. They are also characterized by being less likely to cause ear pain even when tossing and turning in bed.
