※ This is a new, unused item, but it has been opened for photography. 【Excellent Noise Reduction Design】With a dual-layer noise reduction design, it effectively reduces everyday noises such as snoring and talking (noise reduction level: -35dB). It reduces surrounding noise and protects your hearing when studying, working, wanting to sleep, or traveling on trains or airplanes. Recommended for those with hyperacusis or misophonia. 【For Sleep - Doesn't Hurt Your Ears!】The ergonomic and lightweight design ensures no pain or discomfort in your ears even after long periods of wear. Made of soft, skin-friendly silicone material, the shape can be freely adjusted, allowing you to "fit your own ears," which is its greatest feature. Compared to disposable sponge-type earplugs, it is less likely to cause pressure or pain due to urethane expansion, making it recommended for sleep and long-term use. 【Easy to Wear & Washable】Includes four sizes (XS, S, M, L) of ear tips, allowing you to fit your ear size and effectively block out noise. The earplugs are not distinguished between left and right ears, so they are easy to wear simply by inserting the earplugs into the ear canal. Choose the most fitting tip from the size that feels the most comfortable. Because the earplugs touch your skin, you can wash the entire body with water to keep it clean. Moreover, it can be used repeatedly, making it environmentally friendly and easy on your wallet. Comes with a storage case for clean storage and portability for travel and business trips. 【Convenient to Carry & Wide Range of Uses】Comes with an earplug storage case, making it convenient to carry and eliminating the worry of loss. Can be used freely in various situations such as deep sleep, snoring prevention, commuting, trains, airplanes, swimming, travel, studying, reading, work, and mowing the lawn.
