Hearing safety
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.
Be sure to observe the following guide-
lines when using your earpieces.
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 hazard-
ous situations.
Excessive sound pressure from
earphones and headphones can cause
hearing loss.
Using headphones with both ears
covered while driving is not recom-
mended and may be illegal in some
areas while driving.
For your safety, avoid distractions
from music or phone calls while in

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).
