Casti Audiophile Planare, disponibile in culoare alb sau negru, aparitie 2015Closed-Back Planar Magnetic Headphones
Excellent sound quality from planar magnetic drivers
Closed-back design for privacy and noise isolation
High sensitivity, light weight and comfortable fit
Available in Black or WhiteThe OPPO PM-3 combines true audiophile
performance, elegant styling, noise isolation and portability into a
pair of sleek lightweight Planar Magnetic headphones. With the PM-3,
users can easily recreate the experience of listening to a pair of
flagship headphones on a flagship amplifier or a high quality 2-channel
speaker system in an optimised listening room, but in a portable form
factor that could be taken anywhere. Tipping the scale at just
320grams. , the PM-3 is the world's lightest closed-back planar magnetic
headphones. This makes the PM-3 the ideal headphones for a person who is
always on the go. Its elegant styling and exquisite workmanship make
the headphones a pleasure to wear in public, and its light weight and
exceptional comfort make it easy to listen for hours on end. The
closed-back nature of the PM-3 provides isolation from the outside
world, blocking out the surrounding noise while avoiding sound leakage
from the headphones.
Unique Planar Magnetic Sound - Utilising planar magnetic drivers
derived from the award-winning PM-1 headphones, the PM-3 features deep
bass, smooth midrange, and clear treble. The sound signature can be
described as very natural and balanced, with plenty of emotion and
Phase Coherence - When sound enters our ear, it has a planar
wave front with all spectrum components in phase. A typical dynamic
headphone driver disrupts this coherence with its phase irregularity,
resulting in less than perfect signal peak reconstructions. OPPO's
planar magnetic driver has much better phase coherency since all parts
of the diaphragm are vibrating in concert without break up and delayed
Purely Resistive Impedance - OPPO's planar magnetic driver has a
flat conductor pattern that does not have any inductive components.
This eliminates inductance related inter-modulation distortion, which is
especially common in dynamic drivers with high impedance and a high
number of voice coil turns.
7-Layer Diaphragm - OPPO's planar magnetic driver diaphragm has 7
layers of thin materials that provide excellent performance,
reliability, and longevity. The construction of the diaphragm ensures
that it is very stable under thermal stress and vibration.
Double-Sided Spiraling Coils - The diaphragm utilises a
spiraling pattern of flat aluminium conductors on either side of the
driver. The double-sided design allows twice as many conductors to be
placed within the magnetic field, which leads to higher sensitivity,
better damping, and even drive force.
FEM-Optimised Magnet System - An FEM-optimised magnet system
with very high energy Neodymium magnets is used to maximise sensitivity
and consistency of the applied force over the driver area.
Optimised for Mobile Use - Many planar magnetic headphones have a
sensitivity far below 100 dB and require very powerful amplifiers to
drive. The OPPO PM-3 has a sensitivity of 102 dB, which allows it to be
easily driven with mobile devices. Its low impedance works well with
smartphones that ship with low impedance ear buds.
Lightweight and Truly Portable - With a weight of just 320 g,
the OPPO PM-3 is the world's first truly portable closed-back planar
magnetic headphone. It folds flat and comes with a selvedge denim
carrying case. When folded and protected in the carrying case, the PM-3
takes very little space in a briefcase or backpack.
Unparalleled Comfort - Many planar magnetic headphones weigh
over 500 g and are often uncomfortable to wear for more than a short
period of time. Thanks to its light weight, plush padding and carefully
calibrated clamping force, the OPPO PM-3 is a joy to listen for hours on
In-line Mic and Remote - The PM-3 is shipped with a 3 metre main
cable and a 1.2 metre portable cable. Users can choose the best
suitable cable for their mobile devices. This also includes a cable with
mic and controls for Apple devices, one with mic and button for Android
and Windows phones, and one without mic.
Elegant Style - Hi-fi products do not need to look ugly, and
stylish products do not need to sound mediocre. The PM-3 sounds
excellent, looks beautiful, and is equally at home in the fast-paced
urban jungle as in the warmth of a dedicated listening room.
Material and Build Quality - The OPPO PM-3 is ruggedly
constructed with strong metal and plush padding materials. The
headphones have been tested to very high standards to withstand
mechanical and environmental stress in order to guarantee exceptional
performance throughout its lifespan.
Stability, Consistency, Reliability - Many planar magnetic
headphones have large balance deviations between the left and right
channels, and accurate stereo reproduction is contingent on having a
very close match between the left and right channels. During the OPPO
PM-3's manufacturing process, drivers are closely matched to ensure
optimum stereo imaging and soundstage.
Selvedge Denim Carrying Case - The selvedge denim carrying case
included with your OPPO headphones is manufactured using vintage shuttle
looms by a supplier for a number of boutique clothing brands based in
Europe and Japan. The material is a stylish, high-end fabric that is
prized for its ability to weather the elements and develop a unique
aesthetic character over time, and the slim design of the case is a
perfect match with the PM-3prime;s ability to fold flat, allowing the
headphones to fit easily within a backpack or briefcase. Model Name
