Avoid playing your stereophone at high volume levels. Some studies have concluded that
prolonged and extensive exposure to noise in excess of 95dB may impair hearing. Never wear
your stereophone while operating a motorized vehicle. It may create a traffic hazard and is
illegal in many areas. Exercise caution if you are wearing your stereophone while engaged in
activities such as walking, race-walking, jogging, cycling, etc. which may bring you in contact
with vehicular traffic.
