FIIO FT5 Serial Number Headphones Planar Magnetic Field Driver Open Type Headphones FIO-FT5-B [Japan / Included]

---------------------------------------------------------------------- 【Cautions for using electrical products】 When using electrical appliances, please note that the voltage is different from that of Japan, which may cause malfunctions. Since the plug type is Japan type(A or B type), please check the voltage and use a transformer. Please note that a transformer is different from a conversion adapter. We are not responsible for malfunctions caused by use without a transformer.

【Voltage Compatibility】 When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction.

【Plug Type】 Our products use Japanese plug types (A or B type). Please use a conversion adapter if necessary.

【Important Note on Transformers and Adapters】 A transformer adjusts voltage to match your device’s requirements. A conversion adapter only changes the plug shape and does not adjust voltage. Using only a conversion adapter without a transformer may result in damage to the product.

【Liability】 We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer. ----------------------------------------------------------------------

Equipped with a large planar magnetic field driver with a diameter of 90mm, achieving extremely low distortion and a vast sound field feeling: The driver of the FT5 is equipped with a large planar magnetic field driver with a diameter of 90mm. Unlike conventional dynamic types, a planar magnetic field system that drives an extremely low-mass diaphragm sandwiched between magnets over the entire surface eliminates distortion caused by split vibrations and produces sound with excellent transient response over a wide range of 7Hz to 40,000Hz. produces. Printed coil method using a 6μm diaphragm and silver/aluminum mixed material: The diaphragm used in the FT5 uses a PAR material diaphragm with a thickness of 6μm. The planar magnetic field method uses a printed coil method in which a metal material is installed on the material in order to drive the diaphragm sandwiched between magnets. Since using heavy metals such as gold would increase the weight of the diaphragm, the FT5's diaphragm uses semiconductor technology to precisely print aluminum material containing silver. This provides excellent conductivity and reduces the weight of the diaphragm, providing natural and distortion-free sound quality. A total of 20 neodymium magnets create a strong planar magnetic field: FT5 uses 20 neodymium magnets per channel to ensure that the diaphragm can drive in a stress-free and well-balanced manner. Eleven N52 neodymium magnets with a magnetic flux density of approximately 1.5 Tesla are placed on the front and nine on the rear, and the printed coil is sandwiched between them. Efficient magnet placement maximizes the potential of the diaphragm. High-sensitivity, low-impedance design for ease of sound: The FT5 uses a 6μm thin diaphragm to solve the problem of low sensitivity and the need for a large-scale amplifier to sufficiently drive the conventional planar magnetic field method. The high sensitivity of 110dB/1Vrms@1kHz and the low impedance of 36Ω are achieved by the printed coil and strong magnetic field. Even portable players and low-output amplifiers can be sufficiently driven, allowing you to fully experience the product's appeal in any environment. Open structure to effectively control driver back pressure: FT5 uses an open structure to effectively release back pressure without sealing the back of the housing. It has a unique swirl design that precisely controls air flow to achieve high resolution and natural tone. FT5 is FIIO's first open headphone equipped with a planar magnetic field driver. The newly developed planar magnetic field driver is equipped with a 6μm diaphragm using a printed coil made of a silver/aluminum mixed material and a powerful magnetic circuit.By driving the diaphragm with extremely low mass over its entire surface, distortion is extremely low. Produces natural sound with excellent transient characteristics. The lightweight magnesium-aluminum alloy housing provides a comfortable fit, and the high-sensitivity, low-impedance design makes it easy to drive as a portable product, allowing you to listen in a variety of environments.
