Product Information

The product is the ISOtunes ULTRACOMM Aware, a pair of hearing protection earbuds. It complies with the European Safety Standard EN352-2:2020 and the ANSI S3.19-1974 standard. The earbuds come with different types of eartips, including short eartips, tall eartips, and triple flange eartips. The product includes a configurable boom microphone for enhanced voice clarity during phone calls. The earbuds have a Single Number Rating (SNR) of 32 dB and a Noise Reduction Rating (NRR) of 24 dB. The full user manual can be found at ISOtunes.com/manuals.

Product Usage Instructions

1. Fitting: Carefully roll the foam eartip on the stem/sound port and insert it into your ear as deeply as comfortable. Slightly rotate the earbud until it is secure in the bowl of your ear. Make sure the earbud rests tightly next to your inner ear edge. Gently wrap the comfort-fit ear hooks around the top and back of your ears.
2. Phone Calls: Each earbud contains a built-in microphone for making phone calls. To use the included configurable boom microphone for enhanced voice clarity, open the microphone port cover on either earbud and align the arrow on the earbud with the arrow on the boom microphone. Insert the audio jack into the earbud, pressing firmly to ensure it’s fully seated. Remove the boom microphone and store it in the lid of the charging case when not in use.
3. Charging: There are three batteries to charge: the charging case battery, the left earbud battery, and the right earbud battery. To charge the case, insert a USB-C charging cable. The charging case battery indicator light will start flashing to indicate the charge level. To charge the earbuds, place them into the charging case. The earbuds’ indicator light should be solid red, indicating that they are charging. Only use a maximum 5 Volt charger to charge the ISOtunes ULTRACOMM Aware. Using a higher voltage charger may be dangerous and could damage the product.
4. Noise Attenuation: The ISOtunes ULTRACOMM Aware has been tested to have a Single Number Rating (SNR) of 32 dB and a Noise Reduction Rating (NRR) of 24 dB. The NRR is based on the attenuation of continuous noise and may not accurately indicate protection against impulsive noise, such as gunfire. Proper fitting is important for optimal noise attenuation. Refer to the enclosed instructions for proper fitting.

Short Eartips

• SNR (dB) = 30 H84 (dB) = 31 dB M84 (dB) = 26 dB L84 (dB) = 25 dB

Tall Eartips

• SNR (dB) = 32 H84 (dB) = 31 dB M84 (dB) = 30 dB L84 (dB) = 28 dB

Triple Flange Eartips

• SNR (dB) = 30 H84 (dB) = 30 dB M84 (dB) = 28 dB L84 (dB) = 28 dB

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 ear hooks around the top and back of your ears. Power On/Off

Method 1

• Power ON: Open the charging case
• Power OFF: Place earbuds into the charging case and close the lid

Method 2

• Power ON : In OFF mode, press and hold the multi-function button (MFB) for 3 seconds
• Power OFF: In ON mode, press and hold the 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 the 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 “turbocharge” 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.

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.
