your head. The markings
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.
