Please check the actual product images. #plain₋m's products Management number: m27-15360 Effectively soundproofed 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, so it's great for sleep aids. Cuts out unnecessary 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 by washing with water and drying after use. If you feel the noise reduction isn't quite enough, pushing it slightly further into your ear can improve the effect. This product does not block all sounds.
