Introduction
Thank you for purchasing ISOtunes® ULTRACOMM
Aware True Wireless Noise-Isolating Earbuds.
These earbuds are specifically designed for use
in noisy environments – 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.
Fitting
1. Carefully roll the foam eartip
on the stem/sound port (Fig. 1).
2. Insert the eartip into your ear
as deeply as comfortable (Fig. 2).
3. Slightly rotate earbud until it is
secure in the bowl of your ear (Fig. 3).
4. Make the earbud rest tightly next
to your inner ear edge.
5. Gently wrap the comfort-fit earhooks around
the top and back of your ears.
Power On/Off
Method 1
• Power ON: Open charging case
• Power OFF: Place earbuds into charging case
and close the lid
Method 2
• Power ON: In OFF mode, press and hold
multi-function button (MFB) for 3 seconds
• Power OFF: In ON mode, press and hold
multi-function button (MFB) for 3 seconds
Bluetooth® Pairing
After powering on, the earbuds will automatically
enter Bluetooth Pairing Mode. Look for quick
red and blue flashes from the earbud as a
confirmation. Open the Bluetooth® settings on
your device. Search for "ISOtunes ULTRACOMM
Aware." Pair and connect. You will hear "Bluetooth
Connected" once connected.

Phone Calls
Each earbud contains a built-in microphone
for making phone calls. For enhanced voice
clarity, consider using the included configurable
boom microphone.
Open the microphone port cover on either
earbud by pulling up the exposed tab. Then,
align the arrow on the earbud with the arrow
on the boom microphone. Insert the audio jack
into the earbud, pressing firmly to ensure that
it's fully seated.
Remove the boom microphone and store in the lid
of the charging case when not in use.
Charging
There are three batteries to charge:
1. Charging Case Battery
2. Left Earbud Battery
3. Right Earbud Battery
Charging the Case
Insert USB-C charging cable to charge the case.
The charging case battery indicator light will start
flashing to indicate charge level.
Charging the Earbuds
Place earbuds into the charging case. The earbuds'
indicator light should be solid red, indicating that
the earbuds are charging.
Only charge your ISOtunes ULTRACOMM Aware
with a maximum 5 Volt charger. Using a charger
higher than 5 Volts could be dangerous and may
damage your ISOtunes product. Be especially
careful with "quick charge" or "turbo charge"
chargers, which often supply 9, 12, or 15 Volts.
Noise Attenuation
This product has been tested to the European
Safety Standard EN352-2:2020 and the ANSI
S3.19-1974 standard for a hearing protector
with a Single Number Rating (SNR) of 32 dB
and a Noise Reduction Rating (NRR) of 24 dB.
Full testing details are available on page 2
of this booklet.
ANSI S3.19-1974
The level of noise entering a person's ear, when
ISOtunes® ULTRACOMM Aware 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® ULTRACOMM Aware
is 24 dB.
3. The noise level entering the ear is
approximately equal to 76 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
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
medium frequency sounds
(500Hz < f < 2000Hz)
L = Hearing protection estimation for low
frequency sounds (f ≤ 500Hz)
SafeMax™ Technology
ISOtunes® ULTRACOMM Aware incorporates
SafeMax™ Technology; therefore, its volume
output is limited to 85 decibels (IT-75), or 79
decibels (IT-76). ISOtunes® devices with SafeMax™
Technology are ANSI tested and OSHA compliant.
Aware™ Technology
When utilizing the boom mic and listening to
music, Aware Technology will remain useable
and active, based on the user's adjustment.
Once a call is taken or the earbuds are
connected to a communication device, Aware
Technology will turn off. As this device is focused
on use in loud environments, this feature is
meant to allow the user to hear the digital
communication via earbud more clearly.
EN
ULTRACOMM Aware has 4 levels of Aware:
• High
• Medium
• Low
• Off
The levels are changed by tapping the left
earbud on the top of the center panel. Increase
the volume by tapping once, or decrease the
volume by tapping twice. A single beep means
that the level has successfully been raised/
lowered. A double beep means that the highest
or lowest Aware level has been reached.
Cleaning and Maintenance
• Clean your ISOtunes ULTRACOMM Aware 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® ULTRACOMM Aware does an excellent
job of blocking outside noise. As such, ISOtunes®
ULTRACOMM Aware 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® ULTRACOMM Aware is used ONLY in
safe environments.
