Larger than Life Sound
To Hear the Smallest Detail
The OPPO PM-1 Planar Magnetic headphone offers a different way of thinking about planar magnetic technology. The PM-1 is characterized by its natural, dynamic, and engaging sound quality with an emphasis on comfort and reduced weight. It is the result of many years of research led by a team comprised of passionate audio and acoustics engineers, chemical and materials scientists, and audiophiles. A number of technological breakthroughs have made their way into the PM-1, including the use of a unique 7-layer diaphragm, double-sided
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.
Purely Resistive Impedance €“ OPPO™'s planar magnetic driver has a flat conductor pattern that does not have any inductive components. This eliminates inductance related intermodulation distortion, which is especially common in dynamic drivers with high impedance and a high number of voice coil turns.
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-1™'s manufacturing process, drivers are closely matched to ensure optimum stereo imaging and soundstage.
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.
Double-Sided Spiraling Coils €“ The diaphragm utilizes a
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.
High Sensitivity - Many planar magnetic headphones have a sensitivity far below 100 dB and require very powerful amplifiers to drive. The OPPO PM-1 has a sensitivity of 102 dB, which allows it to pair well with both mobile devices and scale upwards when used with
OPPO PM-1 TestingBuild Quality €“ The OPPO PM-1 is ruggedly constructed with an emphasis on
Comfort - Many planar magnetic headphones weigh over 500 g and are often viewed as being uncomfortable. With a weight of 395 g, the OPPO PM-1 strikes a delicate balance between weight, comfort, and elegant industrial design.
Luxury Materials €“ The OPPO PM-1™'s ear cushions are made out of the highest quality natural latex, which is superior and longer lasting to any chemically formulated foam. It is naturally hypoallergenic, retains its mechanical spring-like properties for much longer periods, and resists moisture build up from sweating. The headband and earpads are made of
Easily Replaceable Components €“ The OPPO PM-1™'s earpads are mounted on rubber inserts and can be easily cleaned or replaced. This design also makes switching between the leather and velour earpads nearly effortless. The headphone cable is detachable and uses 2.5 mm mono mini jacks to connect to the earcups, making it easy to switch between the longer, 6.35 mm terminated cable for home
Premium Accessories €“ The 6.35 mm terminated headphone cable features Ohno Continuous Casting (OCC) construction wrapped in a black fabric sleeve. The selvedge denim carrying case transports and protects the headphones in style, and the alternative set of velour pads provides a slightly different sound signature.
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-1™'s ability to fold flat, allowing the headphones to fit easily within a backpack or briefcase.
