Heavys H1H用 ヘッドパッド交換キット（小～標準サイズ）

How it works? We use specialized acoustic filters to reduce volume evenly across all frequencies, rather than just muffling sound like foam plugs. They act as a "low-pass" filter, attenuating harsh, high-frequency sounds while allowing a clear, balanced, and lower-decibel version of the music to reach the eardrum.

Materials: Silicone earplugs, Polycarbonate (PC) filter. 

Color: Transparent with black internal filter

Minim Sound Attenuation: SNR 23 dB | H 26 dB | M 19 dB | L 18 dB

How to use H1F1 Earplugs: 1. Make sure earplugs are clean
2. Hold the end between thumb and index finger
3. Gently pull top of ear outward and upward to straighten ear canal
4. Gently push and twist earplug until it seals comfortably.
To Remove:Gently grip the pull tab and pull. Clean earplugs after use and store them in the protective case
Cleaning: Earplugs can be cleaned with lukewarm water, neutral soap, stored in cool dry place and be completely dry before re-inserting into the ear
