Unlike conventional earplugs, there's no need to roll and compress them; they can be easily and smoothly inserted by twisting and gently pushing them in, achieving excellent hygiene. Once properly inserted, they don't expand and effectively cut noise. Noise reduction rating: 29dB. Easy to insert with new material, Quick-in. Just "putting in earplugs" can improve sleep, concentration, and efficiency in business/study! Use them on trains, buses, or during air travel for a good night's sleep while traveling. They're also great for sharing a room with someone who snores. ● Effectively cuts out annoying and harmful high-frequency noise. ● Noise levels of 85-95dB at busy intersections are reduced to below 60dB, similar to a quiet office.
