Unique Planar Magnetic Sound
Employing planar magnetic drivers that first appeared in the critically lauded PM-1 headphones, the PM-3 comes with deep bass, smooth mids, and crisp highs. The sound signature is very natural and balanced.
Double Sided Spiraling Coils
The diaphragm uses a spiraling pattern of flat aluminum conductors on both sides of the driver. The double-sided design lets twice as many conductors to be placed within the magnetic field, which leads to higher sensitivity, better damping, and even drive force.
Seven Layer Diaphragm
Oppo's planar magnetic driver diaphragm has 7 layers of thin materials that provide excellent performance, reliability, and longevity. The diaphragm's build makes sure that it is very stable under thermal pressure and vibration.
Stability, Consistency & Reliability
Many planar magnetic headphones have large balance digressions between the left and right channels, and accurate sound reproduction is contingent on having a very close match between both. In the PM-3's manufacturing process, the drivers are closely matched to assure optimum stereo imaging and soundstage.
When sound enters your ears, it has a planar wave front with all spectrum components in phase. A typical dynamic headphone driver disrupts this coherence with its phase irregularity, resulting in less than perfect signal peak reconstructions. Oppo's planar magnetic driver has much better phase coherency since all parts of the diaphragm are vibrating together without break up and delayed resonance.
FEM-Optimized Magnet System
A FEM-optimized magnet system with very high energy Neodymium magnets is used to maximize sensitivity and consistency of the applied force over the driver area.
Purely Resistive Impedance
Oppo's planar magnetic driver has a flat conductor pattern that does not have any inductive components. This eliminates inductance related inter-modulation distortion, which is especially prevalent in dynamic drivers with high impedance and a high number of voice coil turns.
Lightweight & Truly Portable
With a weight of just 320 g, the Oppo PM-3 is the world's first absolutely portable closed-back planar magnetic headphone. It folds flat and comes with a selvedge denim storage case. When folded in the case, the PM-3 takes very little space in a briefcase or backpack.
Material & Build Quality
The Oppo PM-3 is robustly constructed with durable metal and plush padding. They have been tested to very high standards to withstand mechanical and environmental pressure so as to guarantee excellent performance throughout their lifespan.
Optimized for Mobile Use
Many planar magnetic headphones have a sensitivity much less than 100 dB and require very powerful amplifiers to drive. The Oppo PM-3 has a sensitivity of 102 dB, which allows it to be easily used with mobile devices. Its low impedance works very well with smartphones.
In-Line Mic & Remote
The PM-3 comes with a 3 meter main cable and a 1.2 meter portable cable. You can choose the best cable for their mobile devices. Available options include a cable with mic and remotes for Apple devices, one with mic and button for Android and Windows phones, and one without mic.

" The Oppo PM-3 is an impressive headphone -- both in terms of build and sound quality -- but just how impressive you think it is will depend on what music you feed it and from what source."
" The Oppo PM-3 are some of the best portable headphones ever made. It has class leading"
" Don't even bother reading this review - just go out and buy these headphones. They're the best available at this price point, offering a stunning balance of closed-back design and planar magnetic sound quality."
"Like a Vitra Eames lounge chair these will pamper you, but rivals have more bite"
" Unlike a lot of the price-sensitive planar magnetic competition, the PM-3 is more than just a great-sounding device. Like the HA-2, it is awesomely outfitted for its price, and awesomely finished at any price. Unlike the HA-2, it is exquisite for use both out and in. Like the HA-2, it is destined to turn the planar magnetic world on its ear. There is literally no planar even double the PM-3’s market value that even interests me anymore."
" don't think I've ever had a headphone come through the lab ticking so many boxes so confidently. Sound quality, styling, comfort, build quality, isolation, and accessorization are all very well executed for this price. The Oppo PM-3 may be the most well rounded headphone offering I've seen to date."
