Larger than Life Sound
The OPPO PM-1 Planar Magnetic headphone offers a different way of thinking about planar magnetic technology. PM-1 is a work of art, combining advanced technology, unique musicality, premium luxury design, resulting in a listening experience that is capable of communicating every nuance of your favorite music.
Hear the Smallest Detail
The result of many years of research led by a team comprised of passionate audio and acoustics engineers, chemical and materials scientists, and audiophiles, the PM-1 holds a number of technological breakthroughs that make it possible to hear the smallest detail.
PM-1 is a luxurious experience in every detail, with hand-selected lambskin ear pads and headband, easily replaceable components, and its premium accessories.
Stability, Consistency, Reliability
During the OPPO PM-1’s manufacturing process, drivers are closely matched to ensure optimum stereo imaging and soundstage.
Unique Planar Magnetic Sound
Utilizing a planar magnetic driver , PM-1 features a transparent, highly dynamic sound that exhibits well-balanced tonal qualities. The diaphragm is evenly driven in a symmetric pull-push manner, and the magnetic system and conductor patterns have been optimized for maximum sensitivity and consistency.
Fem-Optimized Magnet System
Maximizes sensitivity and consistency of the applied force over the driver area.
Double-sided Spiraling Coils
Allows twice as many conductors to be placed within the magnetic field, which leads to higher sensitivity, better damping, and even drive force.
Ensures that it is very stable under thermal stress and vibration.
The artistic polished cherry wood case in luxury style makes the unboxing of the PM-1 an unforgettable experience. The alternative set of velour pads provides a slightly different sound signature.
