    Oppo has announced the release of the PM-1 Planar Magnetic headphones.

    The company describes the PM-1 as:

    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.

    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.
    The PM-1 product page lists the headphones as having a sensitivity of 102db, which means they can be driven by anything from a mobile device to a high-end headphone or tube amp. The frequency response is likely better than most floor standing speakers; 10-50,000 Hz.

    It also has easily swappable components. The earpads are mounted on rubber inserts and can be easily cleaned or replaced. This design also makes switching between the PM-1's 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 use, and a shorter, 3.5 mm terminated cable for portable use.

    While the price of admission is a bit too much for me to justify, $1099, I am sure these are truly lust-worthy headphones.

    Anyone heard a pair?

    I'd sure love to hear them, even though it would be overkill for my old ears. Wonder how they compare with the old Stax brand electrostatics? They were the bee's knees back in their day.

    I should have a pair of these next week for evaluation. Can't wait to hear them first hand.
