Tactical Sound Control™ Technology
This product includes TSC (Tactical Sound Control™) Technology. This is a microphone technology that allows the user to hear the world around them, but always at a safe listening level. When ambient noise breaches a safe listening level, the microphone technology immediately responds and attenuates to a safe level.
Adjusting the TSC Volume is easy. Simply tap the left earbud (2L) once for Aware Volume Up and tap the left earbud (2L) twice for Aware Volume Down.

Introduction
Thank you for purchasing ISOtunes® CALIBER True Wireless Noise-Isolating

Charging
There are three batteries to charge:
- Charging Case Battery

- Right Earbud Battery
Charging the Case
Insert USB type 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’ red indicator light should
be solid red, indicating that the earbuds are charging.
Only charge your ISOtunes CALIBER 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. Your ISOtunes CALIBER cannot be charged at voltage levels above 5 volts.
Battery Capacity
ISOtunes® CALIBER supports Bluetooth® battery level indicator. This means that
when connected to iOS devices, the battery power status can be seen in the
upper right corner of the screen. Please use this as guideline – there are
many factors to battery level accuracy that influence this measurement. (For
example – although the battery power status may show 30% battery power
remaining, this may actually only be 5-10% on your ISOtunes®.)
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 25
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® CALIBER headphones
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® CALIBER is 26 dB.
- 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 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)
