FiiO FT1 Pro Over-Ear Open-Back Planar Magnetic Headphones (Black)

Engineers have constantly strived to achieve a thinner and lighter diaphragm for planar drivers. After two years of independent R & D, FiiO has created an advanced one-micron, ultrathin diaphragm, using high-performance PET as the substrate.

The difference between even a single micron of thickness can produce noticeable changes in the diaphragms ability to vibrate at high speeds, affecting sound quality. The FT1 Pro's one-micron diaphragm is exceptionally lightweight, providing a lightning-fast response. It faithfully reproduces even the subtlest of sounds in the very high frequency range, as well as offering a fantastically wide dynamic range.

The FT1 Pro employs a new self-developed technology for its driver—a patented dual-coating system. By selectively applying a sapphire and aluminum coating in independent layers, audio resolution is improved across the frequency range for nuance.

The first coating layer is made of aluminum, a lightweight and conductive material that enhances the conductivity of traces and improves dynamics while helping to reduce impedance and power requirements. The second coating layer is sapphire, which offers exceptional hardness, improving rigidity for enhanced treble resolution and overall transparency.

The FT1 Pro is equipped with FiiO's new patented acoustic technology, the uniform magnetic field design, which optimizes the uneven magnetic field intensity caused by adjacent magnets and further expands the magnetic field range. The offers a more extensive, precise, and balanced magnetic field, allowing the driver diaphragm to more more evenly with reduced breakup and distortion. This ultimately delivers a more refined sound for capturing even the subtlest of nuances in music—a defining characteristic of planar drivers.

To ensure that the driver diaphragm is manufactured with sufficiently high quality, the FT1 Pro is manufactured using a 28-nanometer process, inspired by the computer semiconductor industry. This process completely isolates the conductive tracing material from the surrounding air.

The driver materia exists in a near vacuum environment at extremely low pressure levels and an extremely high temperature. The trace material is transformed into ionized particles and then accumulates on an ultrathin 1-micron film through charge attraction. This complex process is applied twice to each diaphragm, delivering exceptional sound and fantastic durability.

The lightweight FT1 Pro aims to bring great planar sound without requiring serious amplification. The low 20-ohm impedance, combined with the high sensitivity of 112 dB/Vrms at 1 kHz, means that you can easily get fantastic sound from humble audio sources like smart devices and computers.

Portable and lightweight, the FT1 Pro headband features high-quality ball-bearing steel slides for enhanced durability. This steel-slide adjustment is precise and offers 12 levels of adjustment via notches for various head sizes. The headband sports soft, breathable, and comfortable suede padding, for long listening sessions.

The FT1 Pro inherits the excellent ergonomics of the FT series headphones with its 3-axis adaptive design that flexes to provide multiple angles of action. The earcups offer 35° horizontal angle rotation and 45° pitch rotation, ensuring all head types are comfortable and experience minimal sound leakage.

Experience comfortably long listening sessions with the breathable fabric earpads on the FT1 Pro. This textile material efficiently dissipates heat buildup between the ear cushions and your ears. The side of the cushions is made of of protein leather, which looks and feels great.

The FiiO FT1 Pro comes with two headphone cables—one 3.5mm TRS and one balanced 4.4mm TRRRS. Both cables are made identically with an oxygen-free copper-plated silver wire base with 392 wires at 24 AWG thickness. This makes the FT1 Pro widely compatible with many audio devices. These cables produce a transparent yet robust sound, allowing you to fully enjoy high-quality, lossless audio.
