Oppo Digital PM-1 Planar Magnetic Headphones

For sale are the Oppo PM-1 Planar Magnetic headphones in like new condition. They were a special order for a customer who decided to purchase more expensive headphones before these were delivered. They were removed form the box for inspection and a quick audition then repacked just like it came from Oppo. They are indistinguishable from brand new. If you have been considering purchasing these amazing headphones, do it now and save yourself some money. 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 spiraling coils, and an FEM-optimized magnet system. OPPO Planar Magnetic Technology The OPPO PM-1 utilizes a planar magnetic driver that sets it apart from the majority of headphones on the market. Sound is generated by a very thin and light diaphragm whose entire surface area is evenly driven. The diaphragm is driven in a symmetric pull-push manner, and the magnetic system and conductor patterns have been optimized for maximum sensitivity and consistency. This allows the diaphragm to generate very stable and linear piston-like vibrations, ensuring phase coherence and high resolution performance with minimal distortion. Unique to the OPPO PM-1 is the use of a double-sided diaphragm, which allows us to place twice as many conductors within the magnetic field and eliminate any passive return zones where the conductors do not work. This results in the use of 100% of our conductor length, which in turn results in greater efficiency. In addition, our flat conductor pattern eliminates inductance-related intermodulation distortion, common with dynamic headphones, and the OPPO PM-1’s purely resistive impedance means that sound quality is unaffected by a headphone amplifier’s output impedance. The OPPO PM-1 combines high sensitivity with low weight, allowing it to be used freely with portable devices without requiring additional amplification. Its circumaural, open back design provides the best in sound quality and comfort, and the overall rugged construction ensures that the headphones can withstand mechanical and environmental stress. These aspects of the OPPO PM-1’s design combine to provide a transparent, highly dynamic sound that exhibits well-balanced tonal qualities with very little distortion, resulting in a listening experience that is both free of fatigue and capable of communicating every nuance of your favorite music. Also available is optional BHC-5 (5m Balanced Headphone Cable) which was part of the same order. Please contact me if you have any questions. Thank you!
