The Oppo PM-3 combines true audiophile performance, elegant styling, noise isolation and portability into a pair of sleek lightweight Planar Magnetic headphones. With the PM-3, you can easily recreate the experience of listening to a pair of flagship headphones on a flagship amplifier or a high quality two-channel speaker system in an optimized listening room, but in a portable form factor that can be taken anywhere.
Nudging the scale at just slightly over 10 ounces, the PM-3 is the world's lightest closed-back planar magnetic headphones. This makes the PM-3 the ideal headphones for a person who is always on the go. Its elegant styling and exquisite workmanship make the headphones a pleasure to wear in public, and its light weight and exceptional comfort make it easy to listen for hours on end. The closed-back nature of the PM-3 provides isolation from the outside world, blocking out the surrounding noise while avoiding sound leakage from the headphones.
The PM-3 is available in three cable styles. You can get it with an Apple-compatible portable cable with inline mic and remote, Android-compatible portable cable with inline mic and remote, or audiophile portable cable without mic and remote.
"Sound quality, styling, comfort, build quality, isolation, and accessorization are all very well executed for this price," reports Tyll Hertsens in his May 15, 2015 review for InnerFidelity.com.

Oppo Planar Magnetic Technology
The Oppo PM-3 utilizes a planar magnetic driver that is developed from the driver in Oppo's EISA award-winning PM-1 headphones. Technological breakthroughs achieved during the PM-1's development, such as the seven-layer double-side voice coil diaphragm design and FEM-optimized neodymium magnet system, have enabled Oppo to reduce the weight of the planar magnetic drivers while maintaining excellent sound quality and high sensitivity. This driver would not have been possible without the breakthroughs achieved in the PM-1's driver design.
In the PM-3's planar magnetic driver, sound is generated by a very thin and light diaphragm, which 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.
The PM-3 driver's smaller size and high sensitivity overcome the shortcomings of traditional planar magnetic technology such as being difficult to drive and a heavy weight. This all-new 55 mm diameter round driver is especially suitable for a lightweight close-back design like the PM-3. The PM-3 maintains the very natural and smooth sound signature of the PM-1 and is tuned to have deep, tight bass and a touch of excitement.
Superior Phase Coherence
When sound enters our ear, 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 in concert without break-up and delayed resonance.
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.
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-3s manufacturing process, drivers are closely matched to ensure optimum stereo imaging and soundstage.
Oppo's planar magnetic driver diaphragm has seven layers of thin materials that provide excellent performance, reliability, and longevity. The construction of the diaphragm ensures that it is very stable under thermal stress and vibration.
Double-Sided Spiraling Coils
The diaphragm utilizes a spiraling pattern of flat aluminum conductors on either side of the driver. The double-sided design allows twice as many conductors to be placed within the magnetic field, which leads to higher sensitivity, better damping, and even drive force.
FEM-Optimized Magnet System
An 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.
Optimized for Mobile Use
Many planar magnetic headphones have a sensitivity far below 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 driven with mobile devices. Its low impedance works well with smartphones that ship with low impedance ear buds.
Lightweight and Truly Portable
With a weight of just 10 ounces, the Oppo PM-3 is the world's first truly portable closed-back planar magnetic headphone. It folds flat and comes with a selvedge denim carrying case. When folded and protected in the carrying case, the PM-3 takes very little space in a briefcase or backpack.
Many planar magnetic headphones weigh over 500 g and are often uncomfortable to wear for more than a short period of time. Thanks to its light weight, plush padding and carefully calibrated clamping force, the Oppo PM-3 is a joy to listen for hours on end.
In-line Mic and Remote
The PM-3 is shipped with a 3 meter main cable and a 1.2 meter portable cable. Users can choose the best suitable cable for their mobile devices. Available selections include a cable with mic and controls for Apple devices, one with mic and button for Android and Windows phones, and one without mic.
Hi-fi products do not need to look ugly, and stylish products do not need to sound mediocre. The PM-3 sounds excellent, looks beautiful, and is equally at home in the fast-paced urban jungle as in the warmth of a dedicated listening room.
Material and Build Quality
The Oppo PM-3 is ruggedly constructed with strong metal and plush padding materials. The headphones have been tested to very high standards to withstand mechanical and environmental stress in order to guarantee exceptional performance throughout its lifespan.
Selvedge Denim Carrying Case
The selvedge denim carrying case included with your Oppo headphones is manufactured using vintage shuttle looms by a supplier for a number of boutique clothing brands based in Europe and Japan. The material is a stylish, high-end fabric that is prized for its ability to weather the elements and develop a unique aesthetic character over time, and the slim design of the case is a perfect match with the PM-3’s ability to fold flat, allowing the headphones to fit easily within a backpack or briefcase.
The PM-3 includes a 3 meter cable with 3.5 mm mini-plug and screw-on 1/4" full-size plug adapter. Additionally, you may select one of the following bonus cable that meets your needs: Portable Cable for iPhone: 1.2 meter cable with mic and controls for Apple devices (Black), Portable Cable for Android: 1.2 meter cable with mic and button for Android devices (Black), or Portable Cable Without Mic: 1.2 meter cable without mic and control (Black). This bonus cable offer is in effect for as long as we have the bonus cables in stock.
