Adjusting the bass attenuation
You can use the two supplied sealing tapes to seal the small holes
in the back of the headphone systems. The more holes you seal
with the sealing tapes, the greater is the bass attenuation. This
increases the intellegibility without increasing the volume - which
is an advantage for people with a more severe hearing impairment.
Replacing the ear-cushions
The ear-cushions can easily be removed from the headphones
and cleaned with warm soapy water. From time to time,
however, the ear-cushions should be replaced for reasons of
hygiene. Replacement ear-cushions are available with different
degrees of softness:
Ǡ Black ear-cushions, firmer version Cat. no. 37080
Ǡ Transparent ear-cushions, softer version Cat. no. 40949
Please order your ear-cushions from your Sennheiser dealer.
Volume up? – No!
When people use headphones, they tend to choose a higher
volume than with loudspeakers. Listening at high volume
levels for long periods can lead to permanent hearing defects.
Please protect your hearing, Sennheiser headphones have an
excellent sound quality even at low volumes.
