Headset safety

To use a headset safely, please keep the following in mind:
• Do not play your headset at a high volume. Hearing experts advise against continuous extended play.
• If you experience ringing in your ears, turn down the volume or stop using the headset.
• Do not use a headset while driving a motorized vehicle or riding a bike. It may cause a traffic hazard and
is illegal in many areas.
• Even if your headset is an open-air type designed to let you hear outside sounds, don't turn up the
volume so high that can't hear sounds around you.
