PM-1 Planar Magnetic headphones

The Oppo PM-1 Planar Magnetic headphones offer a different way of thinking about planar magnetic technology. The PM-1 is characterised by 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 spiraling coils, and an FEM-optimised magnet system.

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.

Build Quality
The OPPO PM-1 is ruggedly constructed with an emphasis on long term use and maximum consistency from unit to unit. The headphones have been tested to very high standards to withstand mechanical and environmental stress in order to guarantee exceptional performance throughout its lifespan.

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 high end headphone amplifiers.

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.
