The PM-3 is the lightest closed-type planar magnetic headphone that does not let sounds from the headphones into the environment. The OPPO PM-3 uses the EISA award-winning planar magnetic technology. The development of the PM-3 made a technological breakthrough: a seven-layer diaphragm design with double-sided sonic winding and a magnetic system optimized by the finite element method. The planar magnetic driver of the PM-3 headphones generates sound through a very thin and light diaphragm that oscillates symmetrically in push-pull mode. Rated impedance - 26 Ohm, Driver size (circumference) - 55 mm, Frequency response from 10 to 50,000 Hz.
