Blocks out all kinds of everyday sounds, such as construction sites, commuter trains, and office noise. The advanced algorithm-controlled ANC (Active Noise Canceling) function, equipped with a dual-core digital filter, improves sleep quality and concentration. By wearing them when you are concerned about surrounding sounds, such as when sleeping, working, studying, or in public places, they block out unpleasant sounds in your ears. A "sleep guardian shield for those sensitive to sound" that contributes to hearing protection. 【Sleep-Specific Comfortable Design】 Made of reusable, lightweight, soft silicone material. Ergonomically designed for zero pain or discomfort even after long periods of wear. The "anti-slip/fall prevention structure" that adheres closely to the ear canal ensures ultimate comfort even when sleeping on your side. The aerodynamic shape disperses ear pressure, and the synergistic effect with the ultra-flexible material maximizes soundproofing performance. 【Hygienic, Long Life】 Washable antibacterial silicone (SEK antibacterial certified). Resistant to sweat and sebum, with a 1-year wear guarantee. The included storage case with a strap is convenient for clean storage and portability, and you don't have to worry about losing them. Protects earplugs from dust and moisture. Deep sleep, snoring prevention. Quickly blocks out outside noise, allowing you to enjoy a quiet atmosphere without being disturbed by the outside world. Achieves disturbance blocking in various scenes such as swimming, studying, airplanes, and concerts. 【Universal Fit】 Earplugs that instantly reduce noise and protect hearing in all situations. Recommended for those who want to improve sleep quality, want to reduce noise and sleep soundly, want to concentrate on studying or working, want to protect their ears from noisy environments such as live performances, and those with auditory allergies or phonophobia.
