KYOGOKU BIOSLEEP "Cloud Earplugs" are not just earplugs that block out noise, but a "beauty x engineering" fusion product designed to create a quiet environment that makes it easier for the brain to enter a deep sleep mode. The "Bio-Fit Design," which takes into account the shape of the ear, rolling over movements, and ear pressure, achieves a natural fit that makes you "forget you're wearing them." They fit snugly without being compressed, and don't hurt even after wearing them for a long time. The unique "Silent Shield Core" reduces the frequency bands that interfere with sleep, such as everyday sounds, voices, and air conditioning noise, while adjusting to allow only necessary breathing sounds to reach you. It creates a "deep silence" that you can't experience with ordinary earplugs. Furthermore, the "Two-Layer Antibacterial Coating," which scientifically addresses hygiene, protects against ear sebum and bacteria, allowing for daily clean use. You can carry "your own silence" with you when traveling, staying in hotels, on airplanes, or on the Shinkansen. S/M/L sizes are included. A safe design that allows you to choose the perfect fit for your ears. They are useful in a wide range of situations, such as for sleep, noise reduction, focused work, meditation, and yoga. Comes with a convenient carrying pouch, keeping you comfortable and silent even when you're on the go.
