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 TSC Volume Up and tap the left earbud (2L) twice for TSC Down.
Charging the Earbuds
There are three batteries to charge:
- Charging Case Battery
- Left Earbud Battery
- Right Earbud Battery
Place earbuds into the charging case. The earbuds’ LED Indicator Light (3)
should be solid red, indicating that the earbuds are charging (if the LED
Indicator Light (3)) doesn’t appear, refer to the troubleshooting section at

Important
Please read, understand, and follow all safety information. This product is
designed to protect against harmful noise.
Fitting
ISOtunes ® CALIBER comes with a pair of One-Size-Fits-All TRILOGY™ Triple
Flange eartips and 6 sets of foam eartips tall and short (S,M,L). Choose the
size that fits the most snug in your ear canal. Remember, the snugger the fit,
the better the noise reduction.
ISOtunes ® TRILOGY™ foam eartips have a threaded core, and the sound port of
the earbud is also threaded.
- Carefully compress the foam eartip on the stem/sound port.
- Insert the eartip 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.
Hint: To open your ear canal wider, lift the top of your ear up and away
from your head, as shown in FIG 4.
Please Note: should the included Triple Flange eartips not fit your ears,
all ISOtunes® TRILOGY™ eartips fit this product. Eartips other than the
ISOtunes® TRILOGY™ silicone eartips size are not NRR/SNR rated for ISOtunes
CALIBER, but should offer reasonable attenuation and performance.
Introduction
Thank you for purchasing ISOtunes® CALIBER 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.
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 MFB for 3 seconds.
Power OFF: In ON mode, press and hold 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 CALIBER”.
Pair and connect. You will hear “Bluetooth Connected” once connected.
Charging
There are three batteries to charge:
- Charging Case Battery
- Left Earbud 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)
