FAQ

1Q: Will wearing these earplugs completely block out external sounds?

1A: Sound is transmitted through solid, liquid, or gas mediums. Unless in an almost vacuum-like environment, such as on the moon, it is impossible to completely eliminate sound. However, by wearing earplugs, the sound can be attenuated or reduced to achieve auditory comfort, preventing noise interference and helping with sleep. This product effectively addresses noise-induced insomnia due to its dual effect of ventilation and noise reduction. When worn, it provides a quiet and comfortable auditory experience, making it easier to fall asleep.

2Q: How effective are these earplugs at attenuating high and low-frequency noises?

2A: These earplugs provide a 35dB (NRR35) reduction in high-frequency noise. For low-frequency noise, the attenuation is even more significant, effectively blocking out 80% of low-frequency noise sources below 50dB, such as those found in buildings: elevators, transformers, water pumps in high-rise buildings, central air conditioning systems (including cooling towers), and traffic noise. This product is arguably the only one on the market capable of effectively blocking both high and low-frequency noises, making it the most powerful noise suppressor.

3Q: This product works very well, but why is it priced higher than typical earplugs on the market?

3A: This product, launched in 2013, was specifically developed for sleep. Its core component, the "vented sound reduction valve," is finely crafted, offering excellent ventilation and superior noise reduction. The product's effectiveness far exceeds that of similar products on the market, and it is durable with high resistance to wear and tear. Under normal conditions, it can be used for over 3 years (we offer a three-year free warranty), providing great value for its longevity and performance.

4Q: Why do I feel pressure on my head, ear pain, and discomfort after wearing earplugs?

4A: Most commercially available earplugs are not breathable. While they block out sound, they also prevent airflow inside the ear. When the pressure inside the ear becomes unbalanced with the external pressure, it can cause dizziness, ear pressure, and pain. This product is designed with a focus on human comfort and basic needs. It features a "vented sound reduction valve," which provides both ventilation and sound reduction. This solves two core problems: lack of airflow and noise reduction. It eliminates the discomfort caused by earplugs that are not breathable, such as ear pressure or tinnitus. With this earplug, your ears can breathe naturally, and the "vented sound reduction valve" effectively blocks high-frequency noise (reducing by about 35 dB) and weakens low-frequency noise, significantly improving the product's quality and comfort. It ensures a peaceful, restful sleep.

5Q: When wearing regular earplugs, I often experience noticeable tinnitus and hear my own breathing, which is very uncomfortable. Will this earplug with a "vented sound reduction valve" feel different?

5A: Regular earplugs are not breathable, and when they completely seal off the ear, you can clearly hear your own heartbeat and experience ear discomfort. This product, however, features a "vented sound reduction valve," which allows the ear to continue breathing even when the earplug is in place. It maintains the balance between internal and external pressure, preventing the discomfort typically caused by non-breathable earplugs.

6Q: How does this earplug compare to Sleepsoft and Pluggerz All-Fit earplugs?

6A: The structure and materials of Sleepsoft and Pluggerz All-Fit earplugs are similar. Both use a silicone, umbrella-shaped design with a filter as the core sound filter, which operates based on chemical principles. In contrast, this product (vented sleep earplugs) has a bullet-shaped design with PU foam ear tips, making it more comfortable and providing the best soundproofing and comfort (second to silicone and rubber). The core of this product is the "vented sound reduction valve," which operates on physical principles of sound filtration, offering the strongest noise reduction. After use, it provides a quiet and comfortable auditory experience.

7Q: How often should the ear tips be replaced? Can they be washed with water?

7A: Typically, if used only for sleep, the ear tips can last for over three months. Proper use, such as cleaning the ear canal with a cotton swab before using, can extend their lifespan. However, the actual usage time will vary depending on personal habits and preferences. Since the ear tips are made of PU foam, they are not suitable for washing with water. Over time, they may get dirty, and for hygiene and safety, it is recommended to replace them as needed.

8Q: At what age is this earplug suitable for children?

8A: Children who are 150 cm or taller can use this earplug.

9Q: Does this earplug block low-frequency noise?

9A: Low-frequency noise refers to sounds with a frequency below 500 Hz, which vibrate 20 to 500 times per second. Common sources of low-frequency noise in residential areas include elevators, transformers, water pumps in high-rise buildings, central air conditioning (including cooling towers), and traffic noise. Since low-frequency noise travels through solid materials, its longer wavelength allows it to travel long distances. This penetrating noise can pass through structures, and even with windows and doors closed, it still travels through air vibrations or the conduction through the ground and buildings. This "penetrating noise" can cause pressure on the body, disrupt sleep, affect mental health, and even lead to conditions like nervous breakdowns or depression. Regular earplugs cannot block this type of noise, but because our product's core component, the "vented sound reduction valve," has a sound filtering function, it can effectively eliminate 80% of low-frequency noise sources. The auditory experience becomes comfortable and pressure-free, helping prevent sleep and emotional disturbances, allowing you to sleep peacefully.

10Q: Will wearing this earplug be uncomfortable if I sleep on my side?

10A: This product is designed specifically for sleep, and its compact design makes it very comfortable. The earplug is only 2.3 cm in length, and the portion that extends outside the ear is about 0.5 cm, fitting within the ear concha. Since pillows are soft and elastic, when sleeping on your side, the pillow contours to your ear, creating a small indentation, and the earplug inside your ear remains unaffected. Additionally, the earplug features a flexible and bendable hollow tube inside, which allows the earplug to adjust naturally to the most comfortable position as you sleep on your side. Therefore, this product is very comfortable for side sleepers.

11Q: If I wear the earplugs while working, will I still be able to hear others talking or my phone ringing?

11A: Yes, when worn during work, you can still hear external sounds, including conversations and phone calls. You can maintain normal activities while enjoying personal quiet space. For example, if the office noise level is 70 dB, wearing these earplugs will reduce the sound level to around 35 dB, providing a very quiet and comfortable auditory experience. We recommend using an app to measure the decibel level of the environment you're in.

12Q: Why doesn't this earplug have a connecting cord to prevent it from falling out?

12A: This earplug does not require a connecting cord because the hollow tube inside the ear tip provides strong support and adhesion. Once worn, the earplug stays in place even while side sleeping, and it will not loosen while walking or moving. Therefore, a cord is unnecessary. A cord could create noise from friction with the collar during sleep or activities. If needed, we suggest using a glasses chain or lanyard as an alternative.
