Hearing Safety

Danger

 

To avoid hearing damage, limit the time you use 

headphones at high volume and set the volume to a 

safe level. The louder the volume, the shorter the safe 

listening time is.

Be sure to observe the following guidelines 

when using your headset.

Listen at reasonable volumes for

reasonable periods of time.

Be careful not to adjust the volume

continuously upwards 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.

Excessive sound pressure from earphones

and headphones can cause hearing loss.

Using headphones with both ears covered

while driving is not recommended and may

be illegal in some areas while driving.

For your safety, avoid distractions from

music or phone calls while in traffic or

other potentially dangerous environments.
