【Ultra-Lightweight and Pressure-Free, Doesn't Hurt Ears Even After Long Use】 Made with ultra-lightweight materials, it doesn't put pressure on the ear canal when worn, and it's less likely to shift position even when tossing and turning, allowing for comfortable sleep in any position, whether on your side or back. The ergonomic design conforms to the human ear canal curve, providing a comfortable fit without any discomfort. The gentle materials don't irritate the ear canal skin, reducing the risk of inflammation, so even those with sensitive skin can use them with peace of mind. 【Scientific Soundproofing, Doesn't Miss Important Sounds】 Using high-quality polyurethane foam for the earplugs, it blocks over 90% of everyday disruptive noises such as snoring, car sounds, and crowd noise, instantly creating a quiet environment. However, it's not "completely soundproof," and it moderately retains essential sounds like alarm clocks and mobile phone ringtones, so you don't have to worry about missing important matters without disturbing your rest. It alleviates noise stress and supports deep sleep and focused work/study. 【No Distinction Between Left and Right, Reusable After Washing】 There's no distinction between left and right ears. Simply lift your earlobe slightly when using, and smoothly insert the earplug into the ear canal for easy insertion, making it easy to use even for the elderly and children. The main body is made of soft silicone material with antibacterial properties. If it gets dirty, you can wash it directly with water and dry it for reuse, eliminating the waste of disposable products and making it economical. It rarely hardens or deforms even after repeated use, maintaining a stable fit. 【Comes with a Dedicated Storage Case, Suitable for Multiple Scenarios】 A dedicated storage case is included to protect the earplugs from dust and moisture. The case is compact and easily fits in a bag or pocket, making it easy to carry when traveling or on business trips, and reducing the worry of loss. The uses are also diverse, not only for preventing noise during sleep, but also for supporting concentration during study and work, blocking noise during travel on airplanes and bullet trains, and preventing water from entering during swimming. 【Professional Soundproofing】 Earplugs for Sleep, Complete Soundproofing Civitis Noise Canceling Loop Hypersensitivity Earphones, 35dB Reduction, Good Sleep, Sound Sleep, Noise Reduction, Airplane, Study, Snoring Block, Travel, Live Performance, Work, Ear Tips, Silicone, Reusable, Washable, Ultra-Lightweight, Unisex, Black (XS, S, M, L sizes x 1 set each) 2320 $$1480 #ru-items
