Read this Important Information before Using Your Earbuds

1.) Avoid extended play at very high volume as it may impair your hearing.
2.) If you experience ringing in your ears, reduce the volume or shut off the unit.
3.) Keep the volume at a reasonable level even if your headset is an open-air 
     type designed to allow you to hear outside sounds. Please note that 
     excessively high volume may still block outside sounds.
