Care and maintenance
Cleaning the headset
Use a soft, slightly damp cloth to clean the headset from
time to time. If the headset is very dirty, use a cloth
dampened with mild, soapy water. Do not use any
solvents or cleansing agents.

For reasons of hygiene, the black earpads should be
replaced from time to time. Grasp the edge of the foam
earpad behind the earcup as shown and peel it up and
away from the earcup. Slide the new earpad onto the
earcup. Repeat for the other earcup.
Danger of short-circuit due to the ingress of
water!
Water entering the housing of the headset
can cause a short-circuit and damage the
electronics.
