Flat-Attenuation Hearing Protection with High-Fidelity Clarity
True Sound Precision Powered by Genuine Etymotic® ER-Series Acoustic Filters.
Standard earplugs muffle high frequencies, leaving live sound muddy, distorted, and unnatural. Our custom-fit filtered earplugs house world-renowned Etymotic® ER-Series acoustic filters inside precision-crafted custom silicone earpieces. By replicating the natural acoustic response of the open ear canal, they reduce sound levels evenly across the entire frequency spectrum—protecting your hearing while preserving the rich tone, dynamic range, and vocal clarity of the original sound.
Why Flat Attenuation Matters
Preserves Natural Frequency Balance
Unlike generic foam plugs that roll off crisp highs and boom low-end frequencies, ER-Series filters lower overall volume evenly across all audible frequencies.
Vocal & Instrument Precision
Hear your own voice, bandmates, instruments, or the live stage mix with transparent pitch and tone accuracy.
Reduces the Occlusion Effect
Significantly minimizes the boomy, hollow sensation of hearing your own voice inside your head when singing, talking, or performing.
Effortless Speech Comprehension
Converse clearly with bandmates, venue staff, or concert companions in noisy environments without pulling out your earplugs.
Filter Options: Select Your Attenuation Level
ER‑9
Best For: Acoustic musicians, classical/symphony performers, vocalists, and lighter rehearsal spaces.
Sound Profile: Gentle volume reduction that preserves subtle nuances and low-to-moderate dynamics.
ER‑15
Best For: Performing musicians, guitarists, vocalists, music educators, live audio engineers, and concertgoers.

Interchangeable Flexibility
Acoustic filter buttons easily snap in and out of your custom silicone molds, giving you the freedom to switch filter strengths or swap in solid adapter plugs for maximum isolation.
