IMPORTANT SAFETY INSTRUCTIONS
WARNING!
READ AND UNDERSTAND ALL INSTRUCTIONS. Failure
to follow all instructions listed below, may result in electric
shock, fire and/or serious personal injury.
Read operator’s manual carefully. Learn the applica-
tions and limitations, as well as the specific potential
hazards, related to this device. Following this rule will
reduce the risk of electric shock, fire, or serious injury.
Do not operate battery devices in explosive atmo-
spheres, such as in the presence of flammable liquids,
gases or dust. Battery devices create sparks which may
ignite the dust or fumes.
Do not disassemble the device. Contact with internal
parts may increase the risk of electric shock or cause
damage to the device.
Do not use on a ladder or unstable support. Stable
footing on a solid surface enables better control of the
device in unexpected situations.
Do not store the device in an area of high heat or
humidity. Do not expose the device to extended high
heat from the sun (such as on a vehicle dashboard.)
To reduce the risk of serious personal injury, do not
store outside or in vehicles. Damage to the device or
the battery can result.
Do not expose device to rain or wet conditions. Water
entering a device will increase the risk of electric shock.
Use the device in accordance with these instructions
and in the manner intended for the device, taking into
account the environmental conditions and the work to
be performed. Use of the device for operations different
from those intended could result in a hazardous situation.
Do not insert earphones into ears before connecting
to smartphone.
If you need assistance
The noise reduction capability of these headphones is
30NRR. They will not provide ultimate protection of your
hearing, only reduce the ambient noise; therefore they
may not be suitable for every situation. If at any time you
are uncomfortable using this product, discontinue use
immediately.
The headphones are capable of playing music from
an auxiliary source. This music should not be played if
the music distracts you from your work. The music should
not be played while operating machinery of any kind.
The earphones are capable of producing sound levels
that can be dangerous to long-term hearing. Listening
to music at high volume for any period of time may cause
noise-induced hearing loss. The higher the volume, the
less time required before your hearing may be affected.
Keep out of reach of children. This product contains
small parts that can be a choking hazard to small children.
This product is not intended for use by children.
Always operate the product in compliance with
all local laws and ordinances. This product is not
recommended for use while operating a vehicle.
When servicing the product, use only identical
replacement parts. Follow instructions in the
Maintenance section of this manual. Use of unauthorized
parts or failure to follow Maintenance instructions may
create a risk of shock or injury.
Save these instructions. Refer to them frequently and
use them to instruct others who may use this product.
If you loan someone this product, loan them these
instructions also.

The NRR calculated from these laboratory-based attenuation data is 30. Improper fit of this device will reduce its
effectiveness in attenuating noise. Consult instructions for
use for proper fit.
The level of noise entering a person’s ears when a hearing
protector is worn as directed is closely approximated by
the difference between the A-weighted environmental noise
level and the NRR.
EXAMPLE:
1. The environmental noise level as measured at the ear is
92 dBA.
2. The NRR is 30 decibels. (dB)
3. The level of noise entering the ear is approximately
equal to 62 dBA.
CAUTION: For noise environments dominated by frequencies below 500 Hz, the C-weighted environmental noise
level should be used.

tection 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. (Wording
required by EPA)
The EPA has selected the NRR as the measure of a hearing
protector’s noise reducing capabilities. Aearo Technologies
makes no warranties as to the suitability of the NRR as a
measure of actual workplace protection since such protection is highly dependent on user training, motivation, and
utilization. A better estimate of workplace protection can be
obtained by derating the labeled NRR of this, or any other
hearing protector, by 50%.
