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 hear-

ing adapts.

Do not turn up the volume so high that you can’t

hear what’s around you.

You should use caution or temporarily discon-

tinue use in potentially hazardous situations.

Do not use headphones while operating a mo-

torized vehicle, cycling, skateboarding, etc.; it may

create a traffic hazard and is illegal in many areas.
