Closed-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, Elegant styling and exquisite workmanship
The OPPO PM-3 Planar Magnetic headphones are a revolutionary new lightweight, closed back Planar Magnetic headphone designed with key acoustic and industrial design features. The PM-3 utilises a planar magnetic driver that is derived from the driver in our EISA award-winning PM-1 headphones. Technological breakthroughs achieved through the development on the PM-1s development such as the 7-layer double sided voice coil diaphragm design and FEM-optimised neodymium magnet system have enabled OPPO to reduce the weight of the planar magnetic drivers by 20% while maintaining excellent sound quality and high sensitivity. The PM-3 driver's small size and high sensitivity make it especially suitable for portable use. The enclosed ear cover design offers effective isolation from outside noise allowing you to immerse yourself in music anywhere and anytime.
|The OPPO PM-3 utilises a planar magnetic driver that sets it apart from the majority of headphones on the market. 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 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.
Unique to OPPO planar magnetic headphones 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-3’s purely resistive impedance means that sound quality is unaffected by a headphone amplifier’s output impedance.
The OPPO PM-3 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-3’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 favorite music.
