Important Safety and Usage Information
Before using your headphones, make sure to lower the volume
level on your headphone amplifier or portable device. You can
then raise the volume to your preferred listening level. Please be
aware that prolonged exposure to high volumes may result in
temporary or even permanent hearing loss.
Be aware of your surroundings. Using headphones may diminish
your ability to hear important ambient sounds. Exercise caution
particularly at railway tracks, crossroads, pavements, or any
environment where motor vehicles or bicycles are present.
Turning your audio system on and off, changing inputs, and
connecting or disconnecting the headphones from an audio device
may result in audible high-frequency clicks or pops that may affect
your hearing at high volume levels. It is always recommended to
lower the volume level prior to connecting or disconnecting your
headphones.
Do not leave your headphones or cables in an area where people
or pets might trip over them.
Do not attempt to disassemble or repair the headphones. Service
should only be completed by a qualified OPPO technician.
Always supervise children who are using these headphones.

Congratulations! You are now the proud owner of a pair of
headphones resulting from many years of R&D led by a team of
passionate audio and acoustics engineers, material scientists,
chemical technologists and audiophiles.
The OPPO PM-1 utilises a planar magnetic driver that sets it apart
from the majority of headphones on the market. In our planar
magnetic headphones, sound is generated by a very thin and light
diaphragm whose entire surface area is evenly driven. The
diaphragm is driven in a symmetric pull-push manner, and the
magnetic system and conductor patterns have been optimised for
maximum sensitivity and consistency. This allows the diaphragm
to generate very stable and linear piston-like vibrations, ensuring
phase coherence and high resolution performance with minimal
distortion.

Unique to the OPPO PM-1 is the use of a double-sided diaphragm,
which allows us to place twice as many conductors within the
magnetic field and eliminate any passive return zones where the
conductors do not work. This results in the use of 100% of our
conductor length, which in turn results in greater efficiency. In
addition, our flat conductor pattern eliminates inductance-related
intermodulation distortion, common with dynamic headphones,
and the OPPO PM-1's purely resistive impedance means that
sound quality is unaffected by a headphone amplifier's output
impedance.
The OPPO PM-1 combines high sensitivity with low weight,
allowing it to be used freely with portable devices without
requiring additional amplification. Its circumaural, open back
design provides the best in sound quality and comfort, and the
overall rugged construction ensures that the headphones can
withstand mechanical and environmental stress.
These aspects of the OPPO PM-1's design combine to provide a
transparent, highly dynamic sound that exhibits well-balanced
tonal qualities with very little distortion, resulting in a listening
experience that is both free of fatigue and capable of
communicating every nuance of your favourite music.
We are proud of the work we have done with these headphones,
and we hope they bring you years of enjoyment.

Using Your Headphones
To a Headphone Amplifier,
AV Receiver or Other Mobile Device
To Left Ear cup
To Right Ear cup
Two headphone cables have been included with your OPPO PM-1.
The first cable terminates with a 6.35 mm connector and is
suitable for connecting the headphones to a headphone amplifier,
AV receiver, or integrated amplifier.
The second cable terminates with a 3.5 mm stereo plug and can be
used to connect the headphones to a portable media player,
mobile phone, tablet, or other mobile device.

Storing Your Headphones
Caring For Your Headphones
Removing and Reinstalling the Ear pads
The ear pads can easily be removed by pulling
outwards from the ear cup.
Installing replacement ear pads is as simple
as lining up the pegs on the ear pad with the
respective holes on the ear cup and pushing
the ear pad into the ear cup to secure it in place.
After each use, it is recommended that you place the headphones
on a headphone stand. If you do not anticipate using the
headphones for an extended period of time, it is recommended
that you remove the cable from the headphones and store them
within their box.
In order to clean the headphones, we recommend using a clean,
lint-free cloth. Do not use harsh chemical cleaners or solvents. If
necessary, you may lightly dampen the cloth with clean water.
The ear pads are made of genuine leather and velour fabric, and
they may show wear over time. Replacement ear pads are
available directly from OPPO BD UK Ltd. Note: the ear pads also
contain latex.
