Protect your hearing without sacrificing sound quality. ER20 earplugs use a tuned resonator and acoustic filter to lower volume evenly while preserving clarity. The triple-flange design ensures a secure, comfortable fit, making them ideal for musicians, audiences, and anyone in noisy environments. Reusable, easy to clean, and available in multiple sizes for the perfect fit.
 
Fit & Use:
Two sizes fit almost all ear canals, with the standard fit covering the majority. Insert by gently twisting until the largest flange seals the canal; moisten if needed for comfort.
 
Care & Replacement:
Clean after each use with a damp cloth.
Do not immerse in water or use harsh chemicals.
Replace every 3–6 months with frequent use for best performance.
