Important
Please read, understand, and follow all safety
information. This hearing protector provides
level-dependant functionality, safety-related
audio input, and an entertainment audio facility.
If these recommendations are not adhered to,
the protection afforded by the hearing protector
will be severely impaired.
Fitting
The ISOtunes PRO Aware 2.0 comes with 4 sets
of TRILOGY™ foam eartips (XS,S,M,L) and 1 set
of triple flange silicone eartips. The ISOtunes
PRO Aware 2.0 2.0 EN 352 comes with 4 sets
of TRILOGY™ foam eartips (XS,S,M,L). Silicone
eartips are not EN 352 certified, and therefore
not supplied in the IT-39B package contents.
Choose the size that fits best in your ear canal.
Remember, the snugger the fit, the better the
noise blocking.

remove and clockwise to place on a new
foam eartip.
2. Carefully compress the foam eartip on the
stem/sound port.
3. Insert the foam/eartip into your ear as
deeply as is comfortable and hold for 5
seconds while the foam expands.
4. Repeat with the second eartip.

effectiveness in attenuating noise.
Introduction
Thank you for purchasing ISOtunes PRO Aware
2.0 professional noise-isolating earbuds. These
earbuds have been specifically designed to
protect against harmful noise – allowing you
to block out much of the surrounding noise
so you can listen to your music or talk on the
phone with less interruption. This product has
been tested and meets the ANSI standards for a
hearing protector, with a Single Number Rating
(SNR) of 33 dB and a Noise Reduction Rating
(NRR) of 26 dB. Full testing details are available
in the Noise Attenuation section of this booklet.
Noise Attenuation
ISOtunes PRO Aware 2.0 is tested and approved
in accordance with ANSI S3.19-1974, EN 352-
2:2020, EN 352-7:2020, EN 352-9:2020, and EN
352-10:2020 Specifications.
ANSI
S3.19-1974
The level of noise entering a person's ear, when
these 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.
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 PRO Aware 2.0 is
26 dB.
3. The noise level entering the ear is
approximately equal to 74 dB.
Please note that the NRR is based on the
