Putting on the earphones
CAUTION! Danger of hearing damage!
Listening at high volume levels for long periods can lead to permanent hearing defects. Sennheiser earphones also sound exceptionally good at low volumes.
Set the volume of the audio device to the minimum before switching the earphones on.
Check the R (right) an L (left) marks on the earphones to identify them and put on the earphones as shown in the illustration above.
