A. Safe and Durable: Jayine sleep earplugs are made of silicone and ABS, non-toxic, odorless, healthy and environmentally friendly. Both the outer ring and the earplug head are detachable, easy to clean and long-lasting. These earplugs are suitable for use in scenarios such as sleeping, studying, working, commuting, traveling, and in cafes, allowing you to enjoy quietness at times. B. Effective Noise Reduction: The noise reduction rating (SNR) of these sleep earplugs is 30dB, which can reduce the interference of environmental noise to some extent, enabling you to enjoy your own time and space. Moreover, they will not significantly affect your normal communication with people around you. (Note: These earplugs can provide hearing protection but cannot achieve complete silence.) C. Stylish and Comfortable: The black sleep earplugs are classic and versatile. Besides protecting your hearing, they are also fashionable items! D. Easy to Use: Different from ordinary foam earplugs, these silicone earplugs do not need to be squeezed or waited for. You just need to gently insert them into your ears and then rotate them to adjust to a suitable angle. They are soft in texture, comfortable against the skin, and waterproof, with a relatively wide range of applications. E. Easy to Carry: These noise-reducing earplugs come with a small and lightweight storage case. You can put it in your pocket, bag, or suitcase, or hang it on your keychain, making it convenient to carry. They are also considerate gifts for family members, loved ones, and friends.
