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.

Set your volume control at a low setting.

Slowly increase the sound until you can hear it comfortably

and clearly, without distortion.

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.

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.
