【Sleep Earplugs & Noise Canceling】The constant sound of traffic, the endless barking of dogs, the snoring of family members leaking from the next room... Do you find yourself unable to sleep, constantly checking the clock, and feeling your stress levels rise? Do you wake up in the morning feeling exhausted and unsteady on your feet? This product is designed as a "sleep support and sleep aid" to solve these nighttime problems. 【High-Quality Sleep Environment with Complete Soundproofing】With its unique closed-loop soundproofing technology, this product effectively reduces sleep-disturbing factors such as snoring, everyday noises, and traffic noise, transforming your bedroom into a quiet space. By optimizing the balance between soundproofing and breathability, the design allows you to clearly hear your alarm clock, making it an excellent noise-canceling earplug for maintaining concentration during work or study. 【Comfortable Design for Side Sleeping Without Pain】These completely soundproof earplugs use soft silicone material and an ergonomic ear-ring shape to minimize pressure on the ear canal. With skin-friendly, soft silicone ear tips, they support comfortable sleep without pain or discomfort even when sleeping on your side. Four sizes (SS, S, M, L) are included, allowing you to choose the optimal size for your ears. 【Washable & Comes with a Dedicated Case】The earplugs are made of antibacterial, high-quality silicone, so they can be washed after use to maintain cleanliness, and they are durable and reusable. The included dedicated case makes them convenient to carry and economical. Furthermore, the palm-sized case makes storage easy and portable, making it effortless to take them with you when traveling or on business trips. 【The Ultimate Earplugs for Multiple Scenarios】These earplugs can be used in various situations, including sleep (snoring対策), studying, focused work in the office, on airplanes, and for concert protection. They are also suitable for supporting the daily lives of people with hyperacusis and can be shared by the whole family, regardless of gender. With smart soundproofing technology that selectively blocks specific frequencies, they allow you to hear important sounds (alarms and voices) while effectively cutting out unwanted sounds (e.g., snoring). They were developed as a next-generation item that overcomes the drawbacks of conventional soundproofing earplugs.
