Attenuation section of this booklet.
ANSI S3.19-1974
American National Standards Institute
The level of noise entering a person's ear,
when ISOtunes® FREE 2.0 earbuds 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. ISOtunes FREE 2.0
should not be used if a proper fit is not achieved
or maintained.
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® FREE 2.0 is 25 dB.
3. The noise level entering the ear is
approximately equal to 75 dB.
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.
EN 352
European Comm. for Standardization (CEN)
The product has been tested and approved in
accordance with personal protective equipment
(PPE) standards: EN 352-2:2020, EN 352-9:2020,
and EN 352-10:2020.
The earplugs are provided with level-dependent
attenuation and safety-related audio input
Check correct operation before use. If
distortion or failure is detected, refer to the
troubleshooting advice.
B1: Frequency (Hz)
B2: Mean Attenuation (dB)
B3: Standard Deviation (dB)
B4: Assumed Protection Value (APV) (dB
H = Hearing protection estimation for
high frequency sounds (f ≥ 2000Hz)
M = Hearing protection estimation for
6
medium frequency sounds
(500 Hz < f < 2000Hz)
L = Hearing protection estimation for
low frequency sounds (f ≤ 500Hz)
Please note that the SNR is based on the
continuous wear of the product.
The output of the audio circuit of the hearing
protector may exceed the exposure limit level
Please note, ISOtunes FREE 2.0 provides
an entertainment audio facility.
The audibility of warning signals at a specific
workplace may be impaired while using the
entertainment facility.
Silicone eartips are NOT tested for SNR. Under
EN 352, they are not recommended for use
as hearing protection in noisy environments.
AS/NZS 1270
The reported attenuation will be obtained only
if the protector is in good condition and worn as
directed by AS/NZS 1269.3.

SafeMax™ Technology
ISOtunes® FREE 2.0 incorporates SafeMax™
Technology, therefore its volume output has
been limited to 85 decibels (IT-73 & IT-74),
or 82 decibels (IT-72) . ISOtunes® devices
with SafeMax™ Technology are OSHA and
ANSI compliant.
Cleaning and Maintenance
TRILOGY™ foam eartips should be regularly
inspected for deterioration, cracking, or other
damage. The eartips can be cleaned in between

eartips should be replaced.
• Clean your ISOtunes FREE 2.0 by gently wiping
them with a clean, damp cloth with mild soap.
• Do not immerse the earbuds in water.
• Do not use abrasive cleaning solvents to
clean the earbuds.
• If the earbuds get wet from sweat or rain,
please discontinue use and allow them to dry.
WARNINGS
ISOtunes® FREE 2.0 does an excellent job of
blocking outside noise. As such, ISOtunes®
FREE 2.0 should NOT be used in environments
where users need to be fully aware of their
surroundings for personal safety reasons. For
example, do NOT use them while driving a car or
riding a motorcycle. Similarly, do NOT use them
when riding a bicycle outside. The user is solely
responsible for ensuring that ISOtunes® FREE
2.0 is used ONLY in safe environments.
This product may be adversely affected by
certain chemical substances, such as bug spray
and sunscreen. Further information may be
sought from the manufacturer.
The output of the electrical audio circuit of this
hearing protector may exceed the daily limit
sound level.
These earmuffs are intended to protect your
ears against hazardous noise. The audibility
of warning signals at a specific workplace
may be impaired while using the
entertainment facility.
This product may be adversely affected by
certain chemical substances, such as sunscreen
and bug spray. Further information may be
sought from the manufacturer.
The fitting of hygiene covers to the cushions
may affect the acoustic performance of
the earmuffs.
Noise reduction will be adversely affected by
anything that impairs the seal of the earmuff
cushions against the head, such as thick
spectacle frames, balaclavas, etc. Cushions may
deteriorate with use and should be renewed
regularly.
Recommendations
The wearer should ensure the product is
properly cleaned and dry before and after
use. Storage should be in a clean and dry
location between -20 °C and 50 °C. The battery
