The earplugs have a total length of 2.5 cm, with a base diameter of 1.5 cm, gradually narrowing upward to approximately 1.1 cm at the one-third point, effectively blocking external noise. The bullet-shaped design makes them easy to roll and insert into the ear canal, while the ergonomic design ensures even pressure distribution in the ear canal, minimizing discomfort. The earplugs are soft and comfortable, with low pressure sensation when worn, excellent elasticity, and a snug fit in the ear canal, ensuring comfort even during extended use. They are easy to store, treated for stain resistance, and hygienic to wear. The corded version is suitable for daytime work and daily life, offering convenience for carrying, while the cordless version is more ideal for sleep.
