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, skateboarding, etc.; it
may create a traffic hazard and is illegal in many
areas.
