The Itunes FREE Aware comes with 3 sets of TRILOGY™ foam ear tips (S, M,L), 3
sets of TRILOGY™ Short foam ear tips (S, M, L), and 1 set
of triple flange silicone ear tips. Choose the size that fits best in your ear
canal. Remember, the snugger the fit, the better the noise blocking. The
silicone ear tips are not tested for noise attenuation and should not be used
in noisy environments.
Fitting
- Carefully compress the foam ear tip on the stem/sound port.
- Insert the ear tip into your ear as deeply as comfortable
- Slightly rotate earbud until it is secure in the bowl of your ear.
- Make the earbud rest tightly next to your inner ear edge.
Introduction
Thank you for purchasing ISOtunes® FREE Aware True Wireless Noise-Isolating Earbuds. These earbuds 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.
Controls
[See the Quick Start Guide] Only charge your ISOtunes FREE 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 “turbocharge” chargers, which often supply 9, 12, or 15 Volts. Your ISOtunes LINK 2.0 cannot be charged at voltage levels above 5 volts.
Noise Attenuation APPROVAL
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 25 dB.
ANSI
S3.19-1974
The level of noise entering a person’s ear, when ISOtunes® FREE 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:
- The surrounding noise level measured at the ear is 100 dB.
- The NRR of ISOtunes® FREE Aware is 25 dB.
- 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
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)
