Achieve the optimal soundproofing level for any situation, from concentrated work in a library to casual conversations in a cafe. 20-35dB noise reduction control blocks most noise, allowing you to immerse yourself in a quiet atmosphere wherever you are. Improves sleep quality and concentration, and protects hearing. ✅【Earplugs for Japanese People】Designed with ergonomics in mind, these sleep earplugs are developed to fit the Japanese ear canal, providing a comfortable fit that won't easily fall out during sleep. Furthermore, the high-quality silicone material ensures that your ears won't hurt even after wearing them for a long time. The carefully considered size fits the Japanese ear canal better than other earplugs, providing a natural fit with less discomfort. There's no need to distinguish between the left and right ear, and they won't get in the way when sleeping on your side. ✅【Useful for Noise Reduction】These noise-canceling earplugs are essential for reducing noise during sleep (snoring, construction, etc.) and for concentrating on work. They support deep and comfortable sleep for those suffering from sleep disorders, hyperacusis, or hearing impairments, and for those who have light sleep at night. They are also ideal for when you want to escape the sounds of daily life and concentrate on work, study, or reading. Note: These are not completely soundproof, so you can still hear necessary sounds like alarms and calls, allowing you to use them with peace of mind. ✅【Washable & Wide Range of Uses】Unlike memory foam earplugs, these are made of silicone, so they are soft and comfortable even when worn for long periods. They are gentle on the skin, antibacterial, and can be reused after washing. They can be used freely in various situations, not only for sleep, but also for swimming, travel, study, reading, work, and more. ✅【Lightweight Design & Storage Case Included】The lightweight design makes you hardly feel like you're wearing them. Multiple sizes of ear tips are available, such as XS, S, M, and L, so you can choose the size that fits your ear canal. Furthermore, a storage case is included for a quiet experience you can take with you anytime. ☆29990239 See the product list here #kenta_happyProfileReference #Gift
