PXC 450 Headphones
The PXC 450 is a closed, dynamic, ear-enclosing stereo
headset with newest-generation active noise
compensation (NoiseGard 2.0) for use, for example,
with inflight entertainment systems. Passive and active
tone suppression together enable brilliant music
enjoyment even in noisy environments.

TalkThrough
TalkThrough allows direct communication with your
environment, even while wearing headphones. The
NoiseGard 2.0 and peak level protection remain
active, and your hearing remains protected.
NoiseGard 2.0
The active noise compensation, NoiseGard 2.0, is
based on the principle of deleting tones in the low
frequency range (to 1 kHz) with inverse tones (phase-
inverse tone). Tiny microphones record the ambient
noise. NoiseGard 2.0 electronics creates a sound wave
that is phase-inverted by 180° to the interfering tone
- resulting in the two sound waves almost canceling
each other out.
Additional features
yExcellent sound quality through patented adaptive
baffle damping and duofol diaphragm system
yIdeal for traveling: comfortable, sturdy and folding
design with one-sided cable connection
yPerfectly suited for use in inflight entertainment
systems as well as mobile music sources
yHeadphones can also be used without cable to
dampen noise

Adjusting headband
In order to achieve good sound transmission and noise
damping, as well as the most comfort, adapt the
headband to your head size. You can adjust the
headband using the snap-in locking mechanism.
왘Wear the headphones so that the headband runs
across the middle of your head.
왘Adjust the headphones so that
–theearcushioncompletely surrounds the ears,
– you feel slight pressure around your ears,
– the headband is flat on the head.
왘Check in a loud environment whether the ear
cushions are optimally placed to ensure maximum
noise damping.
Connecting the headphones
왘Connect the audio cable to the headphone
bushing of your sound source.
You will hear the sound from your sound source.
If the plug on the audio cable does not fit:
왘Use the adapter for 6.3-mm plug bushing (see
illustration to the left).
If you wish to use the headphones for the inflight
entertainment in an airplane:
왘Use the inflight adapter (see illustration to the
left).

Daily use
Adjusting the volume
왘Use the VOLUME + button or the VOLUME –
button , to adjust the volume.
Note:
The volume of the TalkThrough signal does not
change.
Listening loud? - No!
People like to listen more loudly with
headphones than with speakers. Loud
volumes for extended periods of time
can lead to permanent hearing loss.
Protect your hearing! Sennheiser head-
phones also sound very good at low
volumes.
CAUTION!
