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 per-
son, even for exposure less than a minute.The higher
decibel ranges are offered for those that may have already expe-
rienced 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 poten-
tially hazardous situations.
