Listening Safely

To protect your hearing, follow these guidelines when you use an earphone.

Set the volume to the lowest setting before you begin listening. After you begin listening, adjust the volume to a comfortable listening level.

Do not listen at extremely high volume levels. Extended high-volume listening can lead to permanent hearing loss.

Once you set the volume, do not increase it. Over time, your ears adapt to the volume level, so a volume level that does not cause discomfort might still damage your hearing.

Traffic Safety

Do not wear an earphone while operating a motor vehicle or riding a bicycle. This can create a traffic hazard and could be illegal in some areas.

Even though some earphones let you hear outside sounds when listening at normal volume levels, they still can present a traf- fic hazard.
