Etymotic Research ER-25: Experience superior hearing protection with high-fidelity sound reduction. Ideal for musicians, the ER-25 earplugs offer 25 dB of flat attenuation across all frequencies, preserving sound quality while safeguarding your hearing. Enjoy long-lasting comfort with reusable, custom-fit earmolds and the flexibility to interchange attenuators for varying levels of protection.

Identifying the earmolds

Right earmold: •red dot

Left earmold: •blue dot or no marking

Insertion

Moisten mold for ease of insertion. Pull the ear

outward and upward while easing the mold into the

ear canal.

Cleaning

Remove attenuator button from mold. Use water and

mild soap on the mold only. Dry mold before replacing

button.

Reasons to replace the molds

and/or attenuators

Discoloration,shrinkage, cracking,hardening of the

earmold material,or deterioration in performance.

General Information

Most attenuator buttons have the number 9,15 or 25

stamped on the button. Some have either a black or

a white sealing ring,others are plain, depending on

the style,color,attenuation characteristics and the

manufacturing process. These identifiers and bands

do not affect the performance of the attenuators.

Each attenuator is carefully constructed and measured

to assure uniform acoustic properties.

Solid Plugs

Some inserts are solid; some have a diaphragm sealed

with epoxy. The average attenuation of Etymotic’s

sealed button is 30 dB, measured at E-A-RCAL

Laboratories by the ANSI Real-Ear-Attenuation-at-

Threshold method. Note:When the sound channel

of the earmold is plugged,the total attenuation is

dependent on the insert plus the earmold seal.

Identifying the Attenuators

Musicians practice and perform

in a variety of different settings

and they are exposed to high

levels of sound, sometimes

for long periods. They require

different amounts of protection,

depending on the sound levels

they encounter during rehearsal

and performance.

Buttons are interchangeable.

Some musicians use one type

of attenuator in one ear and

another type in the other,

depending on the source and

location of sound.
