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.
