1. POWERFUL NOISE REDUCTION The earbuds feature a white drop filter, replaceable earbud tips, and a soundfiltering inner ring. They can reduce noise by up to 35dB, creating a quiet and comfortable sleeping environment for you. 2. QUALITY MATERIAL Our sleep earplugs are made of nano silicone and ABS material, offering a delicate feel without easy staining. They are nontoxic, odorless, healthy, and reusable and washable, providing an alternative to disposable earplugs. 3. COMFORTABLE TO WEAR These earplugs come in three sizes (S/M/L) for a good fit. The soft silicone ensures a sensation experience, allowing peaceful sleep with reduced noise. The teardrop design conforms to your ear's contours, staying in place even when lying on your side or turning over. 4.
