Sendy Audio - Apollo Open-Back Planar Magnetic Headphone (IN STOCK)

QUAD-FORMER TechnologyThe planar magnetic driver is made of double magnets + double sides of coils on diaphragm + double coils on each sides of diaphragm. The coils are arranged with good balance on the diaphragm.Double sides of coils means there is coil on each side of diaphragm. Double coils means there are two coils on each side of diaphragm so there are totally 4 coils on the diaphragm which makes the diaphragm do the same vibration for the same frequency. Double sides magnet provides the same magnetic power in the field.It has excellent electroacoustic energy efficiency conversion extremely low distortion very good consistency and high ability for music reproduction.DriverAfter more than three years of experiments the construction of this planar magnetic driver is designed with the best magnetic circuit and the best magnetic distance to balance the resonance.The high internal damping base material in the composite diaphragm makes natural and soft vocal as well as solid bass.
