The OPPO PM-1 Planar Magnetic headphone offers a different way of thinking about planar magnetic technology. The PM-1 is characterized by a marriage of natural, dynamic, and engaging sound with an emphasis on comfort and reduced weight. It is a result of many years of R&D led by a team of passionate audio and acoustics engineers, chemical and material scientists, and audiophiles. The technology encompasses a wide range of innovative solutions that deliver exceptional performance.

The advantages of planar magnetic technology are based on the fact that in a planar driver, sound is generated by a very thin and light diaphragm that is driven evenly over the entire radiating area. Sound, entering our ear, has a planar wave front at the so called ear reference point (ERP), with all spectrum components in phase. A typical dynamic headphone driver, due to its phase irregularity, disrupts that coherence, resulting in less than perfect signal peak reconstruction, especially of very short impulses. A planar magnetic driver has another advantage that relates to its purely resistive impedance. It has a flat conductor pattern that does not have any inductive component, which eliminates inductance related IM distortion, common in dynamic headphones. A resistive load also ensures that any amplifier will drive the headphones without any changes in spectral balance.

OPPO uniquely integrates many innovations and proprietary methods developed over the years with the latest breakthroughs in materials and manufacturing techniques. Results of this research, focused on eliminating issues affecting many planar magnetic headphones, such as low sensitivity, weight, insufficient diaphragm stability, consistency and reliability, have been implemented in this new technology. The OPPO planar magnetic headphone uses an FEM optimized magnet system with very high energy Neodymium magnets. A large oval planar diaphragm is positioned in an evenly distributed symmetric magnetic field. The diaphragm has a spiraling pattern of flat conductors etched on both sides of a very thin polymer film. The magnetic system and conductor patterns are optimized for maximum driving force (sensitivity) and consistency of the applied force over the radiating area. The double-sided diaphragm has 7 layers of extremely thin materials, each doing a specific job for best performance, reliability and longevity.

These advantages of OPPO’s high resolution planar magnetic technology and advanced headphone design provide for a very open, transparent, and highly dynamic sound that exhibits well-balanced tonal qualities with vanishingly low distortion, resulting in a headphone that communicates every nuance of your favorite music and ensures a high level of emotional engagement. With its classy, industrial fit and finish, the PM-1 is equally at home in an audiophile hi-fi system or on the go with a high resolution portable device.

 

 

Note how much they mention R&D and breakthroughs. R.I.P. affordable price.

Come on, none of you were really expecting a budget/mid price were you? The headphone market is a lucrative one, and companies see it as an area to make margin. I'm still in at $699, but I would'nt be surprised to see the price be as high as $999.

Nah, I dont expect it to be priced low. But it sure would make others and myself very happy if it was  :D

I'm still of the mind that OPPO is going to put out an initial HP to compete in the entry audio price range $400, and then later a higher end (more expensive) version.

That would make me ecstatic, but looking at their info on it so far, and the amp releasing along side of it, its very doubtful.

The amp is getting released in 2014, the HP jack on the BDP-105 can handle HE400's not the harder to push planar magnetic HP's.

Yes, but they're marketing it with pictures side by side, etc.

This could be the LAST puzzle piece to my arsenal,

closed can, portable planar...if its around the price of a MD. :P 

 

Hope its open open .....

Arent planars generally on the heavier side in terms of weight? Personally I dont understand why people want a "portable" solution with planars, the things are freakin heavy.

Maybe it's "I can take it to work" portable. That'd be enough for me anyway.
post #493 of 2487

Because we want good sound in a smaller package? It doesn't necessarily have to be heavier. The original Fostex T10 is a good example of a lightweight portable planar.

It's a fully open design though (fully leaking / non-isolating), in case you don't know.
