Effectively blocks sound with a triple-layer structure of cap, cover, and sponge/silicone. Achieves overwhelming soundproofing with a never-before-seen structure. Soft material made of high-molecular-weight silicone. Comfortable to wear for long periods, reducing ear pain, making it ideal for sleep aids. Cuts out excess noise and sounds as much as possible. Effective for studying for qualifications and exams, training, meditation, as well as at construction sites and live music venues. Can be used hygienically at all times by washing with water and drying after use. If you feel the noise reduction is not sufficient, pushing it slightly deeper into the ear can improve the effect. This product does not block all sounds. *Instant purchase welcome - midnight silent purchase OK ◎ *First come, first served for single items *Bulk purchases welcome, feel free to comment *Free shipping! *Please contact us before evaluation if there are any defects! *Cleaners may be dry. ・Please understand and purchase with home storage and simple packaging (⁎ᵕᴗᵕ⁎) ・Please check the actual photos for the condition of the product♪ ・We have researched the details of the product, but they may differ slightly, so please be sure to check the actual images.
