What Makes Musicians
Earplugs High
Fidelity?
Musicians Earplugs
replicate the natural
response of the ear
canal so that sound
heard with these
earplugs has the same
quality as the
original, just
quieter.

ER•15
C = compliance
L = inductance
R = resistance
 ER•15
ER•15 buttons have a
diaphragm which
functions as an
acoustic compliance,
while the volume of
air in the sound bore
of the custom earmold
acts as an acoustic
mass. The combination
of the two produces a
resonance at
approximately 2700 Hz
(as in the normal
ear), which results in
a smooth, flat
attenuation.
ER•9
The ER•9 has reduced
diaphragm stiffness
for less attenuation.
ER•25
The ER•25 has an increased diaphragm stiffness and an acoustic-mass channel molded into the button for more attenuation.
