Sennheiser headphones sound exceptionally good at low and medium volume levels. ▷ Keep the product, accessories and packaging parts out of reach of children and pets to prevent accidents and choking hazards. ▷ Do not use the product in an environment that requires your special 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. Notes on the use and disposal of storage media You can use the supplied USB flash drive for storing personal data. If the flash drive is sold/passed on or disposed of, the data once stored on it and then deleted using a standard delete method can be recovered with special software and be misused. We therefore recommend using special software for secure deletion of data to ensure that personal data is not misused. We recommend backing up the data saved on your flash drive regularly. Sennheiser does not accept liability for damage or loss of data. 4 | HDV 820
