The OPPO PM-3 is a high sensitivity, light weight, closed-back design for privacy, noise isolation and comfortable fit. As the manufacturer states in the announcement, “with the PM-3, users can easily recreate the experience of listening to live music or a high quality 2-channel speaker system in an optimized listening room, but in a portable form factor that can be taken anywhere. Tipping the scale at just slightly over 10 oz., the PM-3 is the world’s lightest closed-back planar magnetic headphone design. This makes the PM-3 the ideal headphones for a person who is always on the go.”
OPPO also promises that “its elegant styling and exquisite workmanship make the headphones a pleasure to wear, and it is easy to listen for hours on end thanks to its light weight and exceptional comfort. 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 OPPO PM-3 utilizes a planar magnetic driver that is derived from the 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 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.
As OPPO also explains, “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.”
“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.” Available to order right now on OPPO Digital’s web site, the PM-3 has a retail price of $399 and comes with two cables, one long cable for home use and one portable cable for use with mobile devices.
