【Protect Both Ears and Block Out External Noise】Made of high-density, high-quality silicone material, with a maximum Signal-to-Noise Ratio (SNR) of 50 decibels, providing excellent sound insulation performance. It can effectively block out most external noise, allowing you to avoid noise interference in any environment. Not only does it improve concentration and quality in sleep, study, and work, but it also reliably protects your hearing health. 【Silicone Material, Comfortable to Wear】Carefully selected lightweight and soft silicone, designed to fit the shape and contours of Asian ears. It does not cause fatigue or pressure pain in the ears when worn, and it is difficult to fall out even when tossing and turning, nor does it compress the ears, so you won't be disturbed by noise. The comfort is so high that you'll almost forget you're wearing them, providing a comfortable experience throughout. 【Reusable and Washable, with Storage Case】The high-quality silicone ear tips can be washed with water, keeping them clean at all times, allowing for repeated use. The product comes with a dedicated earplug storage case, which is not only convenient to carry but also prevents the loss of earplugs and keeps them clean. 【Multi-Scene Application】Suitable for a wide range of scenarios, such as those who suffer from noise and can't sleep, those with poor sleep quality; those who want to improve concentration; those who want to protect their hearing in high-decibel environments like concerts and clubs; and those with ear problems or auditory hypersensitivity. By choosing this product, you can protect your hearing and well-being. 【Product Guarantee and Package Contents】1 set of earplugs, 1 set each of ear tips (S/M/L sizes), 1 storage case.
