High-performance earplugs certified and recommended by two sleep experts not only reduce noise to the optimal volume as earplugs for sleep, but also reduce noise to a moderate volume when you want to concentrate on studying or work, relax, or even when you are at a live show or taking a nap. [Comfortable to wear for long periods of time] The ear tips are made of soft silicone that is gentle on the skin, so they are comfortable to wear from the time you fall asleep until you wake up.
