Important safety instructions

▷Read this instruction manual carefully and completely before

using the product.

▷Always include this instruction manual when passing the product

on to third parties.

▷Do not use the product if it is obviously defective or makes loud,

unusual (whistling or beeping) noise.

▷Only use the product in environments where Bluetooth® wireless

transmission is permitted.

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 levels for long periods of time. Sennheiser

headphones sound exceptionally good at low and medium volume

levels.

▷The product generates stronger permanent magnetic

fields that could cause interference with cardiac pace-

makers, implanted defibrillators (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.

▷Keep the product, accessories and packaging parts out of reach

of children and pets to prevent accidents. Swallowing and chok-

ing hazard.

▷Do not use the product in an environment that requires your spe-

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

Preventing damage to the product and malfunctions

▷Always keep the product dry and do not expose it to extreme tem-

peratures (hairdryer, heater, extended exposure to sunlight, etc.)

to avoid corrosion or deformation. The normal operating tempera-

ture is from 0 to 40 °C/32 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 ear cups.

▷Use only attachments/accessories/spare parts supplied or rec-

ommended by Sennheiser.

▷Clean the product only with a soft, dry cloth.

▷Use the product with care and store it in a clean, dust-free envi-

ronment.
