Introduction
Thank you for purchasing ISOtunes LINK Aware. This product has 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.
Fitting
- Pull the earcups apart.
- Place the product on your head, securely covering both ears.
- Adjust the earcup position by extending the headband to ensure a good fit around the head and ears.
- When testing the fit, have the product turned off. This will allow you to ensure the passive hearing protection of this product.
- Properly fitted and secured earmuffs will significantly and noticeably reduce outside noise.
Boom Mic
To enhance phone or radio audio quality, use the ISOtunes Boom Mic (sold separately). The Boom Mic accessory is available for purchase at ISOtunes.com.

Aware Technology
This product includes Aware Technology. This is a level-dependent technology that allows the user to hear the world around them. When noise breaches a safe listening level, the LINK Aware immediately responds and cuts out all environmental sound. This reverts the product to a passive hearing protection device. Your product will continue to play any entertainment or communication audio.
Levels __
LINK Aware has 10 levels of Aware:
- OFF
- Low: Levels 1-3
- Medium: Levels 4-6
- High: Levels 7-9
The levels are changed by pressing the UP (+) and DOWN (-) buttons on the right side of the control panel.
Signals __
A single beep means that the level has successfully been raised/lowered. A low-pitched double chime means that the lowest Aware level has been reached (OFF). A high-pitched double chime means that the highest Aware level has been reached.
Batteries and Charging
Charging __
- This product comes with a lithium battery pack. Begin by plugging the included charging cable into a wall outlet or computer port.
- Find the product’s charging port underneath the rubber cover on the bottom of the left earcup.
- Plug the USB-C end of the charging cable into the product’s charging port.
LED Indicators __
While the cable is plugged into the charging port, LED charging indicators will let you know when the battery is fully charged.
- Solid Red = Charging
- Solid Green = Fully Charged
Charging voltage should not exceed 5 V.
Checking or Reinstalling Battery __
- The batteries can be checked by removing the battery cover. Slide the latch to release the door.
- Lift the battery out. Unplug the battery pack cable.
- To reinstall, put the battery pack into the compartment. Then, plug the battery pack cable into the port.
- Ensure the battery pack cable is plugged in properly for proper product performance.
Replacement batteries are available via ISOtunes.com ****
Using AAAs __
- Alternatively, three AAA batteries can power the device. Slide the latch to release the door.

Factory Reset
If you have issues connecting to any device, we recommend a factory reset. Make sure you “forget” or unpair the headphones from your device prior to doing a reset.
- Ensure the headphones are powered on.
- Press and hold the volume up button (+) and the volume down button (-) at the same time for four seconds.

If the hearing protector gets wet from sweat or rain, please discontinue use and turn the earmuff outwards and allow to dry. The ear cushions and foam liners should be regularly inspected for deterioration, cracking, or other damage.
Replacing Ear Cushions __
- Firmly reach into one earcup and tug on the plastic plate behind the ear cushion.
- Pull with force until the ear cushion is removed from the earcup. Do not twist, shear, or cut off. The cushions are secured with a strong snap fit. You may have to pull harder than you think!

SafeMax™ Technology
ISOtunes LINK Aware incorporates SafeMax™ Technology; therefore, its volume output is limited to 85 decibels (IT-34B), or 82 decibels (IT-35B). ISOtunes devices with SafeMax™ Technology are ANSI tested and OSHA compliant and, when designated, meet the European Safety Standard EN352.
Noise Attenuation
ISOtunes® LINK Aware is tested and approved in accordance with ANSI S3.19-1974 Specifications and the European Safety Standard EN 352- 1:2020, EN 352-4:2020, EN 352-6:2020, and EN 352-8:2020.
This earmuff is provided with level dependent attenuation. The wearer should check correct operation before use. If distortion or failure is detected, the wearer should refer to the manufacturers advice for maintenance and replacement of the battery.
American National Standards Institute (ANSI) S3.19-1974
The level of noise entering a person’s ear, when ISOtunes LINK Aware earmuffs 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 LINK Aware is 25 dB. 3. The noise level entering the ear is approximately equal mto 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.
European Committee for Standardization (CEN) EN 352
This product has been tested and meets the European Safety Standard EN352-1:2020, RED directive 2014/53/EU, harmonized Standard EN 60065-2014+A11-2017, EN 62479:2020, ETSI EN 300 328 V2.1.1, ETSI EN 301 489-1 V2.1.1, ETSI EN 301 489-17 V3.1.1 and the ANSI standards for a hearing protector, with a Single Number Rating (SNR) of 30 dB with a Noise Reduction Rating (NRR) of 25 dB. Full testing details are available in the Noise Attenuation section of this booklet.
This product is certified according to the product standards EN 352-1:2020, EN 352-4:2020, EN 352- 6:2020, and EN 352-8:2020.
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)
Criterion level is the sound pressure level in dB(A) of the noise environment resulting in 85 dB(A) effective to the ear while wearing hearing protectors. Three different criterion levels are defined related to the frequency content of the noise.
C1: H = criterion level for high-frequency noise C2: M = criterion level for medium-frequency noise C3: L= criterion level for low-frequency noise
It is recommended that the user should ensure that:
- The earmuffs are fitted, adjusted, and maintained in accordance with the manufacturer’s instructions.
- The earmuffs are worn at all times in noisy surroundings.
- The earmuffs are regularly inspected for serviceability.
If these recommendations are not adhered to, the protection afforded by the earmuffs will be severely impaired.
Recommended Storage – please store in a dry location between use.
AS/NZS 1270
The reported attenuation will be obtained only if the protector is in good condition and worn as directed by AS/NZS 1269.3.

WARNINGS
ISOtunes LINK Aware does an excellent job of blocking outside noise. As such, ISOtunes LINK 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 LINK Aware is used ONLY in safe environments.
The output of the electrical audio circuit of this hearing protector may exceed the daily limit sound level.
These earmuffs are intended to protect your ears against hazardous noise. The audibility of warning signals at a specific workplace may be impaired while using the entertainment facility.
This product may be adversely affected by certain chemical substances, such as sunscreen and bug spray. Further information may be sought from the manufacturer.
The fitting of hygiene covers to the cushions may affect the acoustic performance of the earmuffs.
Noise reduction will be adversely affected by anything that impairs the seal of the earmuff cushions against the head, such as thick spectacle frames, balaclavas, etc. Cushions may deteriorate with use and should be renewed regularly.
