Listening Safely
Do not wear earbuds while driving a vehicle or cycling. This can
create a trac hazard and could be illegal in some areas. To
protect your hearing:
• Do not listen at high volume. Extended high-volume
listening can lead to permanent hearing loss.
• Set the volume to the lowest setting, then adjust to a
comfortable level.
• Avoid increasing the volume. Your ears adapt to volume, so
a level that does not cause discomfort could still damage
your hearing.
