IMPORTANT NOTES ON HEARING
Your hearing is very important to you and to us. We strongly recommend you to follow
the guideline below in order to prevent possible damage to or loss of hearing.
Hearing experts caution that listening to loud sounds can damage hearing over time. With
continuous listening to loud sounds, hearing adapts and will give the impression that
volume has reduced. What seems normal may, in fact, be harmful. To guard against this
before hearing adapts, set the volume at a low level and slowly increase the volume level
until sound can be heard comfortably and clearly without distortion. Damage to hearing is
accumulative and is irreversible. Ringing or discomfort in the ears indicates that the
volume is too loud. Once a comfortable listening level has been established, do not
increase the volume level further.
Cautions
If you experience a ringing sound in your ear, lower the volume or discontinue the use
of this product.
Do not use the headphones while driving or cycling. Because this product reduces
the external noises, you might not be able to hear the warning sounds, such as an
automobile horn, and might result in a traffic accident. Additionally, listening to
headphones while driving is illegal in many places
