safety
instructions
Be sure to observe the following
guidelines when using your headphones.
Listen at reasonable volumes for
reasonable periods of time.
Be careful not to adjust the volume
continuously upwards as your
hearing adapts.
Do not turn up the volume so high
that you can't hear what's around
you.
You should use caution or
temporarily discontinue use in
potentially hazardous situations.
Excessive sound pressure from
earpieces and headphones can
cause hearing loss.
Using headphones with both ears
covered while driving is not
recommended and may be illegal in
some areas.
For your safety, avoid distractions
from music or phone calls while in

environments.
Danger
To avoid hearing damage, limit the time you
use headphones at high volume and set the
volume to a safe level. The louder the volume,
the shorter the safe listening time is.
Hearing safety
General information
To avoid damage or malfunction:
Operating and storage temperatures and
humidity
Store in a place where the
temperature is between -20°C (-4°F)
and 50°C (122 °F) with up to 90%
relative humidity.
Operate in a place where the
temperature is between 0°C (32°F)
and 45°C (113 °F) with up to 90%
relative humidity.
Battery life may be shorter in high or
low temperature conditions.
Replacement of a battery with an
incorrect type risks severely damaging
the headphones and the battery (for
example, in the case of some lithium
battery types).
Caution
Do not expose headphones to excessive heat.
Do not drop your headphones.
Headphones shall not be exposed to dripping or
