PM-3 Closed-Back Planar Magnetic Headphones



UNIQUE SOUND SIGNATURE
  • Unique Planar Magnetic Sound
    Utilizing 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 impact.
  • 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.
  • FEM-Optimized Magnet System
    An FEM-optimized magnet system with very high energy Neodymium magnets is used to maximize sensitivity and consistency of the applied force over the driver area.
  • 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 resonance.
  • Double-Sided Spiraling Coils
    The diaphragm utilizes a spiraling pattern of flat aluminum 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.
  • 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.
  • 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.
 
PREMIUM MOBILITY
  • Optimized 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.
  • 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.

    Hi-fi Sound Meets Style and Comfort
  • 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.
  • Made for iPod, iPhone and iPad
    In-line Mic and Remote
    The PM-3 is shipped with a 3 meter main cable and a 1.2 meter portable cable. Users can choose the best suitable cable for their mobile devices. Available selections include a cable with mic and controls for Apple devices, one with mic and button for Android and Windows phones, and one without mic.
  • 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 end.
  • 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.


  • Selvedge Denim Carrying CaseSelvedge 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-3’s ability to fold flat, allowing the headphones to fit easily within a backpack or briefcase.
