Preventing damage to health and accidents

▷Do not insert the earphones too deep into 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 defibrillators (ICDs) and other implants. Always maintain a distance of at least 3.94"/10 cm between the product component containing the magnet (earbuds and charging case) and the cardiac pacemaker, implanted defibrillator, or other implant.EN_Magnet.png

▷Keep the product, accessories and packaging parts out of reach of children and pets to prevent accidents. Swallowing and chok­ing hazard.

▷Do not use the product in an environment that requires your spe­cial attention (e.g. in traffic). Especially the product’s active noise cancellation can make ambient noise inaudible or drastically change the perception of acoustic warning signals.

Preventing damage to the product and malfunctions

▷Always keep the product dry and do not expose it to extreme tem­peratures (hairdryer, heater, extended exposure to sunlight, etc.) to avoid corrosion or deformation. The normal operating tempera­ture is from 0 °C to 40 °C/32 °F to 104 °F.

▷To avoid loud, unusual (whistling or beeping) noise and to ensure proper noise cancellation, do not cover the microphone openings of the active noise cancellation circuitry located on the outside of the earbuds.

▷Use only attachments/accessories/spare parts supplied or rec­ommended by Sennheiser.
