Using the Headphones
To protect your ears from damage, always
rotate the volume dial of the headphones or
your music device to its lowest position before
wearing the headphones.
1 Attach one end of the furnished
connection cord to the headphones, and
the other end to your music playback
device.
2 Adjust the length of the headband as
you place the headphones over your head.
Place the (R) housing over your right ear, and
the (L) housing over your left ear.
3 Use the VOLUME control dial to adjust
the sound volume.
The sound volume can be adjusted even when
the power switch is set to OFF.
Note
• When disconnecting the cord, pull on the
plug, not the cord.
• When connecting the headphones to an
airline onboard audio system, use the
supplied plug adapter (the adapter may not
comply with the systems used on some
airlines).
• Do not use with airline onboard sound
systems under the following conditions:
– Whenever the cabin crew announces
that electronic devices are prohibited.
– When the use of privately owned
headphones is prohibited inside the
plane.
• When not using the headphones, set the
power switch to OFF.
Normal headphones use
1 Set the headphones’ power switch to
OFF.
Music can be heard even when the power
switch is set to OFF. Sound will be produced in
conventional 2-channel stereo playback, but
the noise-canceller and SRS surround effects
will not function.
Noise canceller
1 Set the headphones’ power switch to
ON1.
The green power indicator will light, and sound
will be heard in 2-channel stereo playback. The
noise canceller function will operate, reducing
the effect of environmental noise and allowing
you to listen at a sound volume lower than that
used when the power switch is set to OFF.

Noise canceller + SRS surround*1
function
1 Set the headphones’ power switch to
ON2.
The green power indicator will light, and both
the noise canceller and SRS surround
functions will operate.
*1 The SRS surround function utilizes SRS HEADPHONE
technology developed by SRS Labs, Inc., (USA) to
reproduce headphone sound with a greater sense of
three-dimensional realism. When using headphones
equipped with SRS HEADPHONE technology, music is
not focused on the center of the head, but is
reproduced with a greater sense of natural expanse.
Note
• The noise-canceller function is designed to
reduce noise primarily in the low-frequency
range, and is not effective at reducing high-
frequency noise.
• If the headphones’ microphone is covered
with your hand or other object, feedback
may be caused, resulting in a “howling”
sound. In this case, remove your hand or
other obstruction from the microphone.
• The effectiveness of the noise canceller
function may vary depending on the way in
which the headphones are worn.
After use
1 Set the power switch to OFF.
Sound can still be heard from the headphones
when the power switch is set to OFF, but the
noise-canceller function will not operate to
lower environmental noise.
Storing the headphones
When not in use, store the headphones as
shown below.
1 Reverse the direction of the ear pads.
2 Fold the headband as shown.
3 Fold the headband as shown to align
with the ear pads.

Troubleshooting
If you suspect a malfunction, perform the following checks, since a simple operating error may be
the cause of the problem. The problem may also be caused by factors other than the headphones
themselves, so be sure to check the sound components with which the headphones are used.
If the problem persists after making the following checks, consult your dealer or nearest Pioneer
Service Station.
Precautions
• Do not subject headphones to dropping,
striking, or other severe impacts, since
damage may result.
• To ensure high quality sound reproduction,
keep the plug clean by wiping occasionally
with a soft clean cloth. A dirty plug may
cause degradation of sound quality or
interruption of sound production.
Environmental conditions
• Avoid leaving the headphones in the
following places:
– Automobiles with closed windows, other
locations exposed to direct sunlight, or
nearby heating appliances or places
exposed to high heat.
– Places exposed to high concentrations
of dust.
– Places exposed to high humidity.
Problem Remedy
No sound. • Check connection between headphones and AV system component.
• Confirm that power is turned on to the AV component.
• Adjust the output sound volume on the AV component.
• Adjust the sound volume on the headphones.
Sound is distorted. • Lower the sound volume on the connected AV component.
• Replace the headphone batteries.
Power won’t turn on. • Replace the headphone batteries.
• Check that batteries are installed correctly (are  and  polarities
correct?).
Feedback sound (howling). • If you are covering the microphone part of the headphone with your
hand, remove your hand.
Noise canceller produces
no effect.
• Set the power switch to position ON1 or ON2 (power indicator lights
green).

About use of headphones
When the sound volume is raised excessively,
sound may leak and bother persons nearby;
avoid excessive sound volumes. In locations
exposed to high levels of noise, it is common to
raise the sound volume to compensate for
surrounding noise, but to ensure safety, the
volume should not be raised so high that you
cannot hear sounds of danger or warning.
Ear pads
The headphones’ ear pad material may
degrade or decompose after extended use or
storage.
Cleaning and care
Keep the headphones clean by wiping
occasionally with a soft cloth. In the event of
severe soiling, dip a clean cloth in a weak
solution of neutral detergent, wring the cloth,
and wipe gently. Never use thinner, benzene,
alcohol or other chemical cleaners since they
will deform the surface material.
In event of malfunction
• In the event of a malfunction, or if a foreign
object becomes lodged in the headphones,
immediately turn off the power and consult
your dealer or Pioneer Service Station.
• When taking your headphones to your
dealer or Pioneer Service Station for
service, be sure to bring both the
headphones and connection cord.
