Oppo PM3 Headphones Steel Blue

Oppo

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.
