FIIO FT5 Serial number Headphones Planar magnetic field driver Open type headphones FIO-FT5-B [Japan / included]

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.

[Product Introduction]

● A vast, finely detailed sound created by a large 90mm planar magnetic driver This product is an open-back headphone that uses the company’s first planar magnetic driver. Equipped with a large 90mm driver, it reproduces everything from delicate musical nuances to grand, expansive sound with rich detail. Taking advantage of the excellent transient response and low distortion unique to planar magnetic technology, it brings out the appeal of audio sources across all genres, including vocals, acoustic instruments, orchestral music, and rock.

● Featuring an ultra-thin 6μm diaphragm The planar magnetic driver uses a 6μm-thick PAR diaphragm. By making the diaphragm itself lightweight, the design enables quick sound attack and agile expression of subtle changes. In addition, the diaphragm uses printed coils made from aluminum material containing silver. This design, which takes into account not only material weight but also conductivity, helps maximize the potential of the planar magnetic driver.

● A powerful magnetic circuit drives the diaphragm across its entire surface The driver uses a total of 20 neodymium magnets. Unlike conventional dynamic drivers, the planar magnetic system drives the thin diaphragm across its full surface, suppressing distortion caused by split vibration and reproducing fine details naturally and accurately. It offers the appeal of abundant information, allowing you to rediscover familiar songs and think, “This sound was in there?”

● A spacious, open soundstage with the clarity unique to an open-back design By adopting an open-back structure, the air behind the driver is effectively controlled. This reduces the sensation of sound being trapped right around your ears, allowing you to enjoy an open sound with a wider sense of space not only left to right, but also front to back. It is especially well suited to content where spatial presentation matters, such as classical music, jazz, live recordings, films, and games.

● High sensitivity and low impedance for easy pairing with a wide range of devices With a low 36Ω impedance and high-sensitivity design of 110dB/Vrms, it is designed to be easy to drive. It works well in a variety of environments, whether with a dedicated desktop headphone amplifier or compatible portable audio devices.

● Lightweight, high-rigidity magnesium-aluminum alloy housing Even with the large 90mm driver, the housing is made from a magnesium-aluminum alloy. It achieves high rigidity while incorporating a design that makes the most of the material’s characteristics.

[Summary] This product is a headphone for those who want to seriously enjoy musical detail and spatial presentation. In addition to the grand scale created by its large driver, it pursues the delicate and fast response characteristic of planar magnetic technology. It is recommended for people who want to enjoy their usual music more deeply, hear the fine expression of vocals and instruments, or experience an open sound with a sense of spaciousness. From the subtle nuances embedded in recordings to a majestic soundstage, this is a carefully designed listening headphone for savoring every sound one by one.
