on to third parties.

Preventing damage to health and accidents

Protect your hearing from high volume levels. Permanent hearing
damage may occur when headphones are used at high volume

exceptionally good at low and medium volume levels.

insert them without ear adapters. Always remove the earphones
slowly and carefully from your ears.
▷
The product generates stronger permanent magnetic fields that
could cause interference with cardiac pacemakers, implanted
defibrillators (ICDs) and other implants. Always maintain a dis-
tance of at least 3.94"/10 cm between the product component
containing the magnet (earbuds and charging case) and the car-
diac pacemaker, implanted defibrillator, or other implant.
▷

of children and pets to prevent accidents and choking hazards.

cial attention (e.g. in traffic or when performing skilled jobs).
