A good noise reduction effect quickly leads to deep sleep. It also works effectively during work and study. [Black Earplugs and Transparent Cord] Earplugs with a cord are less likely to be lost, and can be hung around the neck when removed, allowing for immediate use. The black earplugs are less likely to attract the attention of those around you, and the transparent cord is also difficult to distinguish. It is difficult to notice that they are being worn, making them ideal for working or studying in cafes. The cord is 70cm long. It is adjusted to the optimal length when worn around the neck. It also reduces tangling of the cord due to excessive length. The transparent cord is designed to minimize friction noise with skin and clothing. [Soft, Slim, and Memory Foam] Made of skin-friendly super soft PU foam, the sponge has many fine holes for a gentle fit. The surface is glossy, and the remarkable feature is its shape memory performance, which slowly returns to its original shape over time. After wearing it for a while, it will fit the shape of your ear. These are very ear-friendly earplugs. [Specifications tailored to the size of Japanese ears] The slim specifications are designed to fit Japanese people with smaller ears, reducing discomfort and pain even during long-term use.
