Fitting
ISOtunes® PLUS comes with a pair of One-Size-Fits-All TRILOGY™
Universal foam eartips and 3 sets of silicone eartips (S,M,L)� Choose
the size that ts the most snug in your ear canal. Remember, the
snugger the t, the better the noise reduction. The silicone eartips
are intended for use when NOT in noisy situations�
ISOtunes® TRILOGY™ foam eartips have a threaded core, and the
sound port of the earbud is also threaded�
1� Twist the foam eartip counterclockwise to 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 second eartip�
Hint: To open your ear canal wider, lift the top of your ear up and
away from your head, as shown in FIG 1�
Please Note: should the included Universal sized eartips not t your
ears, all ISOtunes® TRILOGY™ eartips t this product. Eartips
other than the TRILOGY™ Universal size are not NRR/SNR rated
for ISOtunes PLUS, but should oer reasonable attenuation and
performance�
Introduction
Thank you for purchasing ISOtunes® PLUS Professional Noise
Isolating headphones. These headphones have been specically
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 without interruptions� This product has been tested
and meets the European Safety Standard EN352-2:2002 and the
ANSI standards for a hearing protector, with a Single Number Rating
(SNR) of 36 dB and a Noise Reduction Rating (NRR) of 26 dB� Full
testing details are available in the Noise Attenuation section of this
booklet�

ANSI
S3.19-1974
The level of noise entering a person’s ear, when ISOtunes® PLUS
headphones are worn as directed, is closely approximated by the
dierence between the A-weighted environmental noise level and
the Noise Reduction Rating (NRR). Improper t of this device will
reduce its eectiveness in attenuating noise. Consult the enclosed
instructions for proper tting.
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® PLUS is 26 dB�
3� The noise level entering the ear is approximately equal to 74dB�
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 gunre.

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)
