They feature a unique filter that allows only air and necessary sounds to pass through. Unlike urethane earplugs, they don't completely block the ear, so your ears are less likely to get stuffy even after long periods of use. They use medical-grade silicone, which fits gently in the ear and makes it less likely to hurt even when you toss and turn. The product can also be washed with water and reused. [Equipped with a Unique Filter] It has a noise reduction rating (NRR) of 32dB. However, you can still hear necessary sounds like alarms and calls, so you can use them with peace of mind. [Recommended for people like this!] Those who want to improve sleep quality, those who want to sleep soundly, those who want to concentrate on studying or work, those who want to protect their ears from loud environments like live performances, and those with hyperacusis or misophonia.
