Ⅱ. Saccater Noise Reduction Technology: 600-Mesh Membrane in The Multi-layer Microperforated Structure

Luna's design is based on Microperforated Panel (MPP) Structure. The microscopic perforations dissipate acoustic energy as waves pass through. This allows the system to significantly reduce volume while preserving the integrity and clarity of the original sound. Read more about MPP.

Unlike traditional earplugs that simply "plug" your ears—creating a muffled, muddy sound that distorts your music—600-mesh membrane acts as a precision filter. By leveraging this physics, we don't just block noise; we selectively dissipate damaging high-frequency energy while allowing the rich details of speech and music to pass through. Maximum protection without the "underwater" feeling, giving you a more natural listening experience that traditional plugs simply can't match.

Acoustic Performance of Luna Earplugs

The data above shows exactly how Luna's Microperforated Panel (MPP) technology works. Luna acts as a precision filter for your ears instead of blocking all sound indiscriminately.

• 🛡️ Targeted High-Frequency Protection (2000Hz - 8000Hz) The numbers tell the story: Luna is most powerful where it matters most. It effectively neutralizes the most damaging high-pitched noises (like screeching tires or loud speakers), providing a massive 25dB+ reduction in the "danger zone."
• 🗣️ Crystal-Clear Low-Frequency Pass-through In the lower frequencies (below 1000Hz), Luna provides a gentle 13dB reduction. This is the "Sweet Spot"—it’s enough to protect you, but light enough to ensure you can still hear your friends talking and the rich detail of the music without that annoying "muffled" feeling.
• 📈 The "Clarity Curve" Our attenuation isn't a flat line; it’s a rising curve. This means Luna selectively "clips" the harsh edges of loud environments while preserving the natural atmosphere of the sound.

The Bottom Line: Luna doesn't just "plug" your ears—it optimizes your environment. It blocks the pain, but keeps the beat. Read more about NRR & SNR certifications.

Ⅲ. Glow‑in‑the‑Dark: Practical Visibility for Loud Nights

Luna's glow is a practical upgrade built into its very material: we infused strontium aluminate into ABS, and after extensive testing and selection, we now offer 4 color options—teal, marine, pink, and clear. 

By day, each earplug shows its distinct color; after exposure to sunlight, they charge naturally and in darkness all emit a soft, warm‑green glow. This makes Luna the world's first concert earplug with dual color expression—vibrant by day, luminous by night.

This innovative compound captures photons through a quantum-well principle, storing sunlight and releasing it gradually in the dark—no charging, no power, just pure photonic brilliance. 

* Note on Glow Intensity: Glow performance varies by color. Clear offers the brightest luminosity, followed closely by Teal. Marine and Pink provide a more subtle, muted glow. We'll ask your preferred colors via a survey after the campaign ends.

Expose Luna to natural light for around 20 minutes, and it will glow softly for over 6 hours*: The stated glow duration of approximately 6 hours is based on laboratory testing: after full exposure to sunlight, the material was immediately placed in a simulated dark environment, where visible luminescence remained after 6 hours. Instrument measurements indicate that strontium aluminate can emit residual light for up to 10 hours (below the visible threshold of 0.32 mcd/m²). Actual glow performance may vary depending on light exposure, ambient brightness, and individual visual perception.

* In practical applications, such as in completely dark environments like underground stations, tunnels, or parking garages, the glow can remain visible for more than 10 hours. In the presence of ambient light, however, the visible duration depends on whether the surrounding light level exceeds the pigment’s own luminance. If the ambient brightness is higher, the glow may not be perceptible even though emission continues.

Explanation of Strontium Aluminate Brightness Fading

The brightness of Strontium Aluminate gradually fades over time. After being fully charged and placed in darkness, the luminance initially reaches its peak and then slowly decreases. Over 99% of the brightness decreases within the first hour. However, the fading rate slows down significantly afterward, and the glow remains several times brighter than the visibility threshold even at 10 hours.

After exposure to a D65 light source (1000 lux) for 15 minutes, the recorded brightness values are:

• At 10 seconds: 10,288 mcd/m²
• At 2 minutes: 1,721 mcd/m² (an 83.28% decrease)
• At 10 minutes: 394 mcd/m² (a 96.18% decrease)
• At 1 hour: 52 mcd/m² (a 99.51% decrease)
• At 5 hours: 7 mcd/m²
• At 10 hours: 2 mcd/m² (still much higher than the visible light threshold of 0.32 mcd/m²)

Ⅳ. Luna Integrated Set—Built for Complex Noise Environments

ⅰ. Luna High-Fidelity Earplugs

To meet the challenges of complex soundscapes, Luna innovates with a complete set design. At its core are the Glow‑in‑the‑dark High‑Fidelity Earplugs, featuring a 600‑mesh membrane and acoustic channel. Certified at 13 dB NRR, they reduce harmful high‑frequency peaks while preserving low‑frequency detail and musical clarity — perfect for concerts, nightlife, motorcycling, and live events.

ⅱ. Saccater Link: Tug-resistant Magnetic Safety Cord

Never Lose Your Luna: The Saccater Link It's a common story: you're lost in the music at a crowded event, only to realize later that your earplugs have vanished. To prevent this, every Luna Set includes the Saccater Link—a tug-resistant safety cord designed for the boldest crowds. It features soft silicone rings that grip your earplugs securely and magnetic L/R connectors that snap together, turning your cord into a secure necklace when not in use. For your protection, a breakaway safety connector prevents snagging, while the integrated reflective tape ensures you remain visible and your gear stays safe from accidental pulls.

ⅲ. Interchangeable Ear‑Tip Options

To adapt to different ears and canals, Luna provides an unprecedented 14 pairs of ear tips across 3 types. This ensures every user can find their most comfortable fit, with customizable noise reduction ranging from 13 to 30 dB.

• Regular standard tip × 8 pairs: 4 sizes in XS/S/M/L
• Double-tip × 3 pairs: 3 sizes in S/M/L
• Zen-core tip × 3 pairs: 3 sizes in S/M/L

ⅳ. Extra Soft Silicone Earplugs

We also added soft silicone earplugs for situations where the High‑Fidelity model may feel less comfortable — such as side‑sleeping. Optimized for maximum noise reduction and comfort. With interchangeable tips, they deliver up to 30 dB attenuation, ideal for sleep, travel, study, or deep concentration. And it's also glow-in-the-dark and easy to find in your bed.

ⅴ. Upgraded On-the-go Carry Case

The newly upgraded on‑the‑go Carry Case was redesigned based on backer's feedback. We replaced the fragile silicone lanyard with a durable paracord, ensuring long‑term reliability and easier attachment to bags, keyrings, or hooks. 

To make glow charging more convenient, the case now features a transparent lid — so even when your earplugs are stored inside, they can still receive light and recharge their glow. This thoughtful upgrade keeps your Luna earplugs secure, visible, and always ready for use.

ⅵ. Specifications

* Under normal use and proper storage, the primary material—ABS and silicone—is engineered to last up to five years. However, actual lifespan may vary depending on environmental conditions, usage habits, and accidental damage.

• In practical applications, such as in completely dark environments like underground stations, tunnels, or parking garages, the glow can remain visible for more than 10 hours. In the presence of ambient light, however, the visible duration depends on whether the surrounding light level exceeds the pigment’s own luminance. If the ambient brightness is higher, the glow may not be perceptible even though emission continues.
