It can effectively block out most of the 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 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, without putting pressure on 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 a 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 for carrying but also prevents the loss of earplugs and keeps the earplugs clean at the same time. 【Multi-scene対応】 Suitable for a wide range of situations, such as those with poor sleep quality, those who want to improve concentration, those who want to protect their hearing at concerts, clubs, etc., and those with ear problems or hyperacusis.
