Listening Cautions
Do not play your headphones or earphones at a high volume.
Hearing experts advise against continuous extended play.
If you experience a ringing in your ears, reduce volume or discontinue use.
Do not use while operating a motorized vehicle. It may create a traffic hazard and is illegal in
many areas.
You should use extreme caution or temporarily discontinue use in potentially hazardous
situations.
Even if your headphones or earphones are the open-air type designed to let you hear outside
sounds, don’t turn up the volume so high that you can’t hear what’s around you.
Sound can be deceiving. Over time your hearing “comfort level” adapts to higher volumes of
sound. So what sounds “normal” can actually be loud and harmful to your hearing.
Guard against this by setting your equipment at a safe level BEFORE your hearing adapts.
To establish a safe level:
Start your volume control at a low setting.
Slowly increase the sound until you can hear it comfortably and clearly, and without distortion.
Once you have established a comfortable sound level:
Leave it there.
