  • 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 optimized listening room, but in a portable form factor that could be taken anywhere.
  • Tipping the scale at just slightly over 10 oz., 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.

Planar Magnetic Technology 

  • The OPPO PM-3 utilizes a planar magnetic driver that is developed from the driver in our EISA award-winning PM-1 headphones.
  • Technological breakthroughs achieved during the PM-1's development, such as the 7-layer double-side voice coil diaphragm design
  •  FEM-optimized neodymium magnet system, have enabled us to reduce the weight of the planar magnetic drivers while maintaining excellent sound quality and high sensitivity.
  • This driver would not have been possible without the breakthroughs achieved in the PM-1's driver design.
  • In the PM-3's planar magnetic driver, sound is generated by a very thin and light diaphragm which is driven in a symmetric pull-push manner, and the magnetic system and conductor patterns have been optimized 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.
  • The PM-3 driver's smaller size and high sensitivity overcome the shortcomings of traditional planar magnetic technology such as being difficult to drive and heavy weight.
  • This all-new 55 mm diameter round driver is especially suitable for a lightweight close-back design like the PM-3.
  • The PM-3 maintains the very natural and smooth sound signature of the PM-1, and is tuned to have deep, tight bass and a touch of excitement.
