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. Headphones of the Sennheiser
brand sound exceptionally good even at low and medium volume
levels.
▷
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. when performing skilled jobs).
Preventing damage to the product and malfunctions
▷
Allow the product to stand for at least 2 hours before putting it
into operation. Condensation can form inside the product if it is
moved from a cold environment to a warm environment.

We recommend using the latest DAC (digital-to-analog converter)
firmware for your headphone amplifier and the latest driver for your
operating system (MacOS, Windows).
