Hearing Comfort and Well-Being


To prevent possible hearing damage, do not listen at high volume levels for long periods.

  • Do not play your personal audio at a high volume. Hearing experts advise against continuous extended play.
  • If you experience a ringing in your ears, reduce volume or discontinue use.

Traffic Safety

  • 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.
  • Do not turn up the volume so high that you cannot hear sound around you.


To reduce the risk of electrical shocks, fire, etc.

  • Do not disassemble or modify the unit.
  • Do not allow flammable, water or metallic objects to enter the unit.

For your safety...

  • Stop using the headphones if they are causing great discomfort or irritation on the skin and the ears. They may damage your skin and cause rash or inflammation.
  • If ear piece or other parts of headphones become lodged in your ear, be careful not to push it deep into the ear canal and seek skilled medical assistance to remove the piece. Damage to the ear may be caused by non-professionals attempting to remove the piece.
  • Store the ear pieces in a safe place where children cannot reach them to avoid the risk of a possible accident or hazard such as swallowing them.
