good at low and medium volume levels.

your ears and never 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 defibril-
lators (ICDs) and other implants. Always
maintain a distance of at least 3.94"/10 cm
between the product component containing
the magnet and the cardiac pacemaker,
implanted defibrillator, or other implant.

packaging parts out of reach of children and
pets to prevent accidents. Swallowing and
