The
PM-2 Planar Magnetic headphones from
Oppo are characterised by natural, dynamic, and engaging sound quality with an emphasis on comfort and reduced weight. They use the same driver as the PM-1, and the same technological breakthroughs are present in the PM-2: 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-2’s manufacturing process, drivers are closely matched to ensure optimum stereo imaging and soundstage.
Build Quality The OPPO PM-2 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-2 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.
