DJcong, a company offering items that support your sleep environment, will be selling "DJcong Sleep Earplugs" at a special limited-time price to coincide with Amazon Prime Day, from Tuesday, July 7, 2026, to Monday, July 13, 2026.

During this period, gray will be sold for ¥1,708 (down from the regular price of ¥2,850), black for ¥1,799 (down from ¥2,999), and green for ¥1,797 (down from ¥2,999).

Familiar sounds that can be bothersome when you want to sleep, such as car engine noise, a partner's snoring, pets barking, or everyday household sounds.

DJcong focuses on the stress caused by these everyday noises and has been developing products with an emphasis not only on sound insulation but also on "ease of long-term wear," "comfort when sleeping on your side," and "a design that blends into daily life."

After 18 months of research and trials, these earplugs combine a natural fit like earbuds with a minimalist design that doesn't immediately suggest they are earplugs for sleeping.

For nights when you want to sleep but are bothered by nearby sounds:

"I can't sleep because I'm bothered by my family's snoring." "I'm bothered by the sound of cars and motorcycles." "I wake up to the sound of my pet or household noises."

Sound-related concerns vary from person to person.

DJcong Sleep Earplugs are designed not to completely eliminate surrounding sounds, but to soften bothersome everyday noises and help you spend more peaceful time.

As certified hearing protection, they offer noise reduction performance of SNR 26dB and can be used not only for sleeping but also in various situations where concentration is needed, such as reading, studying, teleworking, or during travel.

Designed with ear comfort in mind, born from 18 months of research and trials

When prioritizing sound insulation, ear pressure can be a concern.

On the other hand, when prioritizing comfort, a sufficient fit may not be achieved.

DJcong has pursued a balance between the sound insulation and wearing comfort required of earplugs, conducting 18 months of research and trials.

This product uses flexible silicone material. The 3D design, which considers the shape of the ear, is designed to reduce pressure on the ear during long periods of wear and when sleeping on your side.

When sleeping on your side, where your ear is likely to touch the pillow, the protrusion or hardness of earplugs can be bothersome. This product has a compact shape that naturally conforms to the area around the ear, taking into account movement during sleep.

CE Certified, SNR 26dB Noise Reduction Performance

DJcong Sleep Earplugs have obtained CE certification as hearing protection and feature SNR 26dB noise reduction performance.

They can be used in various situations where surrounding sounds are a concern, including snoring and household noises during sleep, during travel on trains or planes, and during times when you need to concentrate on work or study.

They do not completely block out necessary sounds, but rather soften bothersome surrounding noises, supporting an environment where you can more easily focus on your own time.

Easy to fit each individual's ear with 4 sizes of ear tips

Ear size and shape vary from person to person.

Therefore, this product comes with four sizes of ear tips to accommodate different ear sizes. By choosing the size that fits your ear, you can adjust the balance between fit and sound insulation.

Furthermore, the main unit can be reused and is washable. As it is an item for daily use, it is finished to be easy to use for a long time while maintaining cleanliness.

Minimalist design that also focuses on "not looking like earplugs"

Earplugs are not just for the bedroom.

Sounds can be bothersome in various everyday situations, such as on trains during commutes, in the office, at cafes, libraries, or during flights.

DJcong has adopted a simple, minimalist design similar to earbuds so that they can be used naturally even when out and about.

With a design that is inconspicuous around the ears and suitable for various fashions and situations, these earplugs can be incorporated not only for sleep but also for times when you need to concentrate or spend time quietly.

Choose from 3 colors to match your mood and style

For this Amazon Prime Day, three colors – gray, black, and green – will be sold at a special limited-time price.

Gray, with a calm impression that blends easily into daily life; black, simple and suitable for any occasion; and green, adding a subtle accent to your ears.

You can choose the color that best suits your lifestyle, not just for sleeping but also for work or travel.

From sleep to focused time, create "quiet time for yourself" in your daily life

Sound is invisible, but it is one of the familiar elements that influence the comfort of sleep and focused time.

DJcong has been developing earplugs that are easy to use continuously in daily life, not just by blocking sound, but by focusing on long-term wearability, consideration for side sleeping, and a design that is easy to use even when out.

Time before sleep, time to concentrate on work, time to enjoy reading, time to rest quietly during long-distance travel.

DJcong Sleep Earplugs are designed to accompany those "times when you want to spend a little quieter" in your life.

During Amazon Prime Day, from Tuesday, July 7, 2026, to Monday, July 13, 2026, all three colors will be sold at a special limited-time price.
