Soft silicone earplugs, noise-canceling for sleep, reusable, airplane earplugs (js)

Dual-frequency filtering allows noise to "seamlessly penetrate." A specially designed high- and low-frequency sound filter effectively reduces the impact of sound waves on the eardrum; the double-layer umbrella-shaped structure features a closed-loop laminated design. 30-second slow rebound memory: Made of selected foamed PU material, safe and healthy, the slow rebound memory alleviates ear canal discomfort caused by excessively rapid rebound. Dense ventilation holes reduce noise layer by layer, maintaining ear canal breathability and comfort; soft and comfortable, with no foreign body sensation when worn. Washable and reusable: Both silicone and foam materials are washable and can be reused after complete drying, convenient, quick, and long-lasting. Block noise, protect hearing, and enjoy a good night's sleep! These noise-canceling earplugs are ideal for sleep, construction sites, concerts, hunting, ear protection, anti-snoring, and hearing protection in various noisy environments.
