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.
