PM-1 Planar Magnetic Headphones

Los auriculares Planar Magnetic OPPO PM-1 ofrecen una manera diferente de pensar en la tecnología Planar Magnetic. PM-1 se caracteriza por su natural, dinámica y atractiva calidad de sonido con un énfasis en el confort y la reducción de peso.

PM-1 es el resultado de muchos años de investigación de un equipo compuesto por ingenieros y científicos amantes de la música.

Los auriculares de OPPO PM-1 se han hecho un hueco gracias a una serie de avances tecnológicos como el uso de un único diafragma de 7 capas, bobinas de doble cara en espiral, y un sistema magnético optimizado-FEM.


The OPPO PM-1 Planar Magnetic headphone offers a different way of thinking about planar magnetic technology.

The PM-1 is characterised by a marriage of natural, dynamic, and engaging sound with an emphasis on comfort and reduced weight. It is a result of many years of R&D led by a team of passionate audio and acoustics engineers, chemical and material scientists, and audiophiles. The technology encompasses a wide range of innovative solutions that deliver exceptional performance.

The advantages of planar magnetic technology are based on the fact that in a planar driver, sound is generated by a very thin and light diaphragm that is driven evenly over the entire radiating area. Sound, entering our ear, has a planar wave front at the so called ear reference point (ERP), with all spectrum components in phase. A typical dynamic headphone driver, due to its phase irregularity, disrupts that coherence, resulting in less than perfect signal peak reconstruction, especially of very short impulses. A planar magnetic driver has another advantage that relates to its purely resistive impedance. It has a flat conductor pattern that does not have any inductive component, which eliminates inductance related IM distortion, common in dynamic headphones. A resistive load also ensures that any amplifier will drive the headphones without any changes in spectral balance.

OPPO uniquely integrates many innovations and proprietary methods developed over the years with the latest breakthroughs in materials and manufacturing techniques. Results of this research, focused on eliminating issues affecting many planar magnetic headphones, such as low sensitivity, weight, insufficient diaphragm stability, consistency and reliability, have been implemented in this new technology. The OPPO planar magnetic headphone uses an FEM optimized magnet system with very high energy Neodymium magnets. A large oval planar diaphragm is positioned in an evenly distributed symmetric magnetic field. The diaphragm has a spiraling pattern of flat conductors etched on both sides of a very thin polymer film. The magnetic system and conductor patterns are optimized for maximum driving force (sensitivity) and consistency of the applied force over the radiating area. The double-sided diaphragm has 7 layers of extremely thin materials, each doing a specific job for best performance, reliability and longevity.

These advantages of OPPO’s high resolution planar magnetic technology and advanced headphone design provide for a very open, transparent, and highly dynamic sound that exhibits well-balanced tonal qualities with vanishingly low distortion, resulting in a headphone that communicates every nuance of your favorite music and ensures a high level of emotional engagement. With its classy, industrial fit and finish, the PM-1 is equally at home in an audiophile hi-fi system or on the go with a high resolution portable device.
