Instructions for use
The PXC 350 headphones
The PXC 350 are closed, dynamic, circumaural stereo
headphones with NoiseGard Advance active noise
compensation technology, designed for use with e.g.
in-flight entertainment systems. Passive and active
noise reduction enable you to enjoy music even in
noisy environments.

NoiseGard Advance
The NoiseGard Advance active noise compensation
system is based on the principle of cancelling out
sound using “anti-sound” (phase-inverted sound).
Tiny microphones pick up low-frequency ambient
noise (up to 1 kHz) near the ear. The NoiseGard
Advance electronics use this noise to generate a
sound wave which is the exact opposite (IE: at the
same level but polarity reversed – 180° out-of-
phase), the effect being that the polarity reversed
signal cancels most of the outside noise.
Additional features
yOutstanding sound quality due to patented
adaptive baffle damping and Duofol diaphragms
yOptimum protection against ambient noise due to
NoiseGard Advance active noise compensation
yGreat for travel: comfortable, rugged and foldable
headphone construction with single-sided cable
yDesigned for use with in-flight entertainment
systems and audio, video and game consoles
yWithout the detachable audio cable, the head-
phones can be used as passive hearing protectors

Adjusting the headband
For optimum transmission quality, good noise
attenuation and best possible comfort, the headband
has to be adjusted to properly fit your head:
왘Wear the headphones so that the headband
runs over the top of your head.
왘Adjust the length of the headband so that
– your ears are completely inside the earpads ,
– you feel even, gentle pressure around your ears,
– a snug fit is ensured.
왘Final adjustment is best made in a noisy environ-
ment!
Connecting the headphones
왘Connect the audio cable to the headphone
socket of your sound source.
You hear the sound from your sound source.
If the plug on the audio cable does not fit:
왘Slip on the audio adapter for ¼" (6.3 mm) jack
socket (see diagram on the left).
If you want to use the headphones with an in-flight
entertainment system:
왘Slip on the in-flight adapter (see diagram on the
left).

Using the PXC 350
Adjusting the volume
왘Turn the volume control VOLUME to adjust the
volume.
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 head-
phones also sound exceptionally good
at low volumes.
CAUTION!
