WARNINGS
Read, understand, and follow these instructions to ensure safe
operation. Keep these instructions for future reference.
These hearing protectors help reduce exposure to hazardous noise and
other loud sounds. Misuse or failure to wear hearing protection at all times
that you are exposed to noise may result in hearing loss or injury.
• Silicone tips on earbuds DO NOT provide hearing protection.
ONLY memory foam tips on earbuds provide hearing protection.
• Use only appropriately sized Klein Tools memory foam tips for hearing
protection in loud-noise environments. Improper fit of this device will
reduce its effectiveness in attenuating noise. Consult the OPERATING
INSTRUCTIONS section for proper fit.
• Prolonged exposure to high volumes can cause hearing damage.
It is the responsibility of the user to set the audio input level to the
recommended volume. See table on next page for noise exposure levels.
• DO NOT use this product in situations that require special attention:
using noise reduction equipment and listening to audio can reduce
awareness of the surrounding environment.
Failure to observe these warnings can result in risk of re or electric shock.
• DO NOT use the product if it is damaged or modified. Damaged or
modified batteries may exhibit unpredictable behavior resulting in fire,
explosion, or injury.
• Risk of fire and burns. DO NOT open, crush, heat above specified
maximum temperature or incinerate. Prolonged exposure to direct
sunlight can result in elevated temperatures.

WARNINGS
• DO NOT immerse in water or other liquids.
• Properly seal the charging port cover to achieve specified water & foreign
object ingress protection. Keep seal free of dirt, oil, sand, or other material
that interferes with proper sealing. Failure to do so can result in risk of fire
or electric shock.
• DO NOT open the charging port cover if wet or in a wet environment.
Thoroughly dry the unit and the seal around water-resistant cover
completely before opening water resistant cover
• DO NOT subject to impacts or drops greater than 6.6ft (2m). Drops larger
than this may not show signs of damage, but internal components may
have been compromised. It is advisable to replace the unit if any such
severe events occur.
• DO NOT attempt to repair the product or charging cable. There are no
user-serviceable parts.

NOISE REDUCTION RATING (NRR)
The NRR for the AESEB1S SMART SENSE Situational Awareness
Bluetooth®Earbuds is 26dB. It is tested and in accordance with ANSI
S3.19-1974. To ensure adequate hearing protection, the provided memory
foam tips must be used with the Bluetooth®Jobsite Earbuds.

The level of noise entering a person’s ear when the hearing protector is
worn as directed, is closely approximated by the difference between the
A-Weighted environmental noise level and the Noise Reduction Rating
(NRR).
EXAMPLE:
• The environmental noise level as measured at the ear is 93dB(A).
• The NRR is 26dB.
• The level of noise entering the ear is approximately equal to 67dB(A).
ENGLISH

NOISE REDUCTION RATING (NRR)
CAUTION: For noise environments dominated by frequencies below 500
Hz, the C-weighted environmental noise level should be used.
NOTE: Although hearing protectors can be recommended for protection
against the harmful effects of impulsive noise, the Noise Reduction Rating
(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. The Environmental Protection Agency uses the Noise
Reduction Rating (NRR) as a rating of a hearing protector’s noise-reducing
performance. Klein Tools cannot guarantee the suitability of the NRR as a
method of rating protection as protection relies on the level and exposure
of sound and how well a product fits.
AUDIO INPUT LEVEL
The audio level in the hearing protector is dependent on the audio input
level. To prevent harmful noise levels, the AESEB1S SMART SENSE
Situational Awareness Bluetooth®Earbuds automatically default to
85dB when connected to music device. If the hearing protector is
connected to a music device with a high audio output level, it is the
user’s responsibility to set the audio input level to safe level. See table in
WARNINGS section for noise exposure levels.

OPERATING INSTRUCTIONS
CHARGING THE CASE
Open the USB-C Port Cover
7
and insert the USB-C end of the included
charging cable
10
into the USB-C Port
8
of the charging case. Connect
the USB-A end of the cable into an appropriate charging source (not
included, see GENERAL SPECIFICATIONS section).
While the case is charging (0% to 99%), the Charging Case LED

will
breathe red (dim to bright). Once the case is fully charged (100%), the
Charging Case LED
6
will turn green.
CHARGING THE EARBUDS
Provided the charging case has been charged, open the Charging Case
cover
5
and place the earbuds in their respective slots. The Charging
Case LED

USING MEMORY FOAM TIPS
11
FOR HEARING PROTECTION
WARNING: Inspect before each use. Damage to the memory foam tip
can reduce noise reduction performance.
INSERTING EARBUDS INTO EARS
The AESEB1S comes with three silicone
12
and three memory-foam
11
eartip sets:
The silicone eartips
12
are best suited for casual or leisure use.
The memory foam
11
eartips must be worn for hearing protection (NRR):
1. Choose the eartip size (S/M/L) that best fits your ear canal and install onto
the earbuds (FIG. A). Inspect each tip for dirt and damage before use.
2. With clean hands, roll and compress the memory foam tips along the
stem of the earbud (FIG. B).
3. Reach over your head with free hand to pull your ear up and back and
insert the memory foam tip portion of the earbud as deep as possible
(FIG. C).
4. Hold the earbud and wait 30 seconds, until the memory foam tips are
fully expanded (FIG. D).
5. Rotate the earbud if necessary to make sure the earbuds rest firmly and
securely inside the inner ear (FIG. E).
6. Repeat process for other earbud.
