Hearing safety
Listen at a moderate volume.
Using headphones at a high volume can
impair your hearing. This product can
produce sounds in decibel ranges that
may cause hearing loss for a normal
person, even for exposure less than a
minute. The higher decibel ranges are
offered for those that may have already
experienced some hearing loss.
Sound can be deceiving. Over time your
hearing ‘comfort level’ adapts to higher
volumes of sound. So after prolonged
listening, what sounds ‘normal’ can
actually be loud and harmful to your
hearing. To guard against this, set your
volume to a safe level before your hearing
adapts and leave it there.
To establish a safe volume level:
Set your volume control at a low setting.
Slowly increase the sound until you can
hear it comfortably and clearly, without
distortion.
Listen for reasonable periods of time:
Prolonged exposure to sound, even
at normally ‘safe’ levels, can also cause
hearing loss.
Be sure to use your equipment
reasonably and take appropriate breaks.
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 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. Do not use headphones while
operating a motorized vehicle, cycling,
