Achieves overwhelming soundproofing with a never-before-seen structure. Soft material made of high-molecular-weight silicone. Comfortable to wear for long periods, making it suitable as a sleep aid. 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 venues. Can be used hygienically by washing with water and drying after use. If you feel the noise reduction is not sufficient, pushing it slightly further into your ear may improve the effect. This product does not block all sounds.
