Product Information

The ISOtunes ULTRACOMM Aware earbuds are designed to provide hearing protection while also allowing for communication and phone calls. These earbuds come with three types of eartips – Short Eartips, Tall Eartips, and Triple Flange Eartips – each with different noise attenuation levels. The earbuds have been tested to comply with the European Safety Standard EN352-2:2020 and the ANSI S3.19-1974 standard, providing a Single Number Rating (SNR) of 32 dB and a Noise Reduction Rating (NRR) of 24 dB. The product has a built-in microphone for making phone calls and comes with a configurable boom microphone for enhanced voice clarity. The earbuds can be charged using a USB-C charging cable.

Product Usage Instructions

1. Read and understand all safety information before using the ISOtunes ULTRACOMM Aware earbuds.
2. Select the appropriate eartip based on the desired noise attenuation level.
3. Carefully roll the foam eartip on the stem/sound port and insert it into your ear as deeply as comfortable.
4. Slightly rotate the earbud until it is secure in the bowl of your ear.
5. Make the earbud rest tightly next to your inner ear edge and gently wrap the comfort-fit earhooks around the top and back of your ears.
6. For phone calls, open the microphone port cover on either earbud, align the arrow on the earbud with the arrow on the boom microphone, and insert the audio jack into the earbud. Remove the boom microphone and store it in the lid of the charging case when not in use.
7. Charge the earbuds and the charging case using a maximum 5 Volt charger. The charging case battery indicator light will start flashing to indicate charge level.

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 earhooks around the top and back of your ears.

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