Following up on the company's well-received PM-1 headphones, OPPO Digital has released a closed-back version of the planar magnetic headphones: the $399 PM-3. The closed-back design allows for better noise isolation, and the PM-3 boasts a higher sensitivity and lighter weight than the open-back PM-1. The PM-3 is available now through OPPO's website.
On the heels of rolling out its HA-2 portable headphone amplifier, OPPO Digital has released the PM-3 Closed-Back Planar Magnetic Headphones, adding another perfect companion for music on the go.
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 re-create the experience of listening to live music or a high quality two-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. 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.
Key features of the PM-3 include:
• Excellent sound quality from planar magnetic drivers
• Closed-back design for privacy and noise isolation
• High sensitivity, light weight and comfortable fit
• Elegant styling and exquisite workmanship
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 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 of heavy weight. This all-new 55mm-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 website, 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.
