Putting the headphones on and adjusting
the headband
For good sound quality and best possible wearing comfort, the head-
band can be adjusted to properly fit your head.
▷ Wear the headphones so that the headband runs over the top of
your head. The markings R
for the right side and L for the left side
can be found on the inside of the headband.
▷ Move the ear cups up or down the headband slider until:
– your ears are comfortably covered by the ear pads,
– you feel even, gentle pressure around your ears,
– a snug fit of the headband on the head is ensured.
For optimal sound quality, the ear pads must completely surround
your ears.
