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, users can easily recreate the experience of listening to a pair of flagship headphones on a flagship amplifier or a high quality 2-channel speaker system in an optimized listening room, but in a portable form factor that could be taken anywhere. Tipping the scale at just slightly over 10 oz., the PM-3 is the world's lightest closed-back planar magnetic headphones.
An Engaging Planar Magnetic with the
Style and Portability You’ve Been Looking For...
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.
Planar Magnetic Technology
The OPPO PM-3 utilizes a planar magnetic driver that is developed from the driver in our EISA award-winning PM-1 headphones. Technological breakthroughs achieved during the PM-1's development, such as the 7-layer double-side voice coil diaphragm design and FEM-optimized neodymium magnet system, have enabled us 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 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.

"the PM-3 is peerlessly thoughtful and exquisitely finished. There is no planar magnetic headphone out there south of a grand that can contend with it. "
"They are a superb way for the enthusiastic listener who senses that there is more to hear to enter the upper ranges of audio and also one of the best ways to take exceptionally high fidelity "on the go". Very highly recommended."
"The PM-3 made me want to keep them on beyond the review process and just enjoy my music; outside! So on the first day of spring, with a spring in my step, I snagged my iPhone, actually left the house, and did just that."
"the company’s first pair of closed-back planar magnetic headphones. That basically means that it can crank out excellent sound, but because of the closed-back design, it hoards all of the audio for the listener—and all while isolating the sounds of the outside world."

"Previously my go-to recommendations for closed back headphones were the PSB M4U, NAD HP50, and Sennheiser Momentum. The OPPO PM-3 outshines them all and will be one of the most confident product recommendations I have ever offered."
Home Theatre Review
"With its deep bass, smooth midrange, and clear treble, the PM-3 delivers a very natural and balanced sound with plenty of emotion and impact."
"The PM-3 delivers both sound quality and style in spades, and challenges headphones costing twice as much."
