Introduction
Thank you for purchasing ISOtunes® LINK Aware
Professional Noise Isolating Earmuffs. These
earmuffs have been specifically designed for use
in noisy environments – allowing you to block
out much of the surrounding noise so that you
can listen to your music or talk on the phone with
less interruption. This product has been tested
and meets the European Safety Standard EN352-
1:2002, RED directive 2014/53/EU, harmonized
Standard EN 60065-2014+A11-2017, EN
62479:2020, ETSI EN 300 328 V2.1.1, ETSI EN 301
489-1 V2.1.1, ETSI EN 301 489-17 V3.1.1 and the
ANSI standards for a hearing protector, with a
Single Number Rating (SNR) of 30 dB with a Noise
Reduction Rating (NRR) of 25 dB. Full testing
details are available in the Noise Attenuation
section of this booklet.
Noise Attenuation APPROVAL
ISOtunes® LINK Aware is tested and approved in
accordance with ANSI S3.19-1974 Specifications
and the European Safety Standard EN 352-
1:2002, EN 352-4:2001, EN 352-6:2002, and EN
352-8:2008.
This earmuff is provided with level dependent
attenuation. The wearer should check correct
operation before use. If distortion or failure
is detected, the wearer should refer to the
manufacturers advice for maintenance and
replacement of the battery.
ANSI
S3.19-1974
The level of noise entering a person's ear,
when ISOtunes® LINK Aware headphones
are worn as directed, is closely approximated
by the difference between the A-weighted
environmental noise level and the Noise
Reduction Rating (NRR). Improper fit of this
device will reduce its effectiveness in attenuating
noise. Consult the enclosed instructions for
proper fitting.
A1: Frequency (Hz)
A2: Mean Attenuation (dB)
A3: Standard Deviation (dB)
Example:
1. The surrounding noise level measured at the
ear is 100 dB.
2. The NRR of ISOtunes® LINK Aware is 25 dB.
3. The noise level entering the ear is
approximately equal to 75dB.
Please note that the NRR is based on the
attenuation of continuous noise and may not be
an accurate indicator of the protection attainable
against impulsive noise, such as gunfire.
EN352
This product is certified according to the product
standards EN 352-1:2002, EN 352-4:2001, EN

B1: Frequency (Hz)
B2: Mean Attenuation (dB)
B3: Standard Deviation (dB)
B4: Assumed Protection Value (APV) (dB)
B5:
H = Hearing protection estimation for high
frequency sounds (f ≥ 2000Hz)
M = Hearing protection estimation for medium
frequency sounds (500 Hz < f < 2000Hz)
L = Hearing protection estimation for low
frequency sounds (f ≤ 500Hz)
Criterion level is the sound pressure level in
dB(A) of the noise environment resulting in 85
