Sound of nature american black walnut solid wood cups the fiio ft1 cups are made from carefully selected fas grade american black walnut. The woods smooth grain unique to each piece and delicate texture truly showcase its natural beauty. This highly dense solid wood also helps to reduce cavity resonance effectively and minimizes standing waves. 60mm large dynamic driver the fiio ft1 features a newly developed second generation 60mm large dynamic driver, meticulously designed specifically for fiios first closed back over ear headphones. Its larger than average driver size enhances energy conversion efficiency and provides a solid foundation for potent bass. Additionally, the increased driver size results in lower low frequency resonance points, allowing for deeper bass, dynamic sound, and an overall authoritative sound. Art of sound the fiio ft1, in alignment with its overall acoustic design and high level listening experience, employs a nanowood fibre composite diaphragm. This diaphragm is composed of carefully selected paper fibres combined with a lightweight pu polyurethane suspension gasket. It exhibits excellent high frequency extension and transient response, resulting in a clean, precise sound with clear imaging tone, and providing you with the unique sweet, rich, and high density mid frequency vocals of paper diaphragms. This driver works in harmony with the ft1s other acoustic design elements for a specially tuned frequency response for a pure and pleasant sonic experience. It is as if the elegant aesthetics of the ldquopaperrdquo driver translates perfectly into beautiful sound. Cutting edge technology and innovative applications the fiio ft1, as the first closed back over ear headphones from fiio, pioneers a new generation of in house acoustic technologymdashthe w shaped suspension gasket. The 25mm diameter voice coil is larger compared to similar models and has been specifically optimized and tuned. Compared to typical similarly sized diaphragms, the w shaped diaphragm achieves a 25.8% increase in effective vibrating area, allowing it to store more energy reserves. The ft1s diaphragm, with a hard dome and compliant suspension gasket, allows the 25mm large diameter voice coil 25mm large diameter voice coil to directly drive the stiffer dome region. This setup minimizes vibration losses between different materials and reduces distortion caused by driver breakup, allowing the ft1 to deliver refined sound. Ultra fine japanese ccaw voice coil to ensure robust and high quality sound, the fiio ft1 utilizes a specially imported japanese ultra fine ccaw copper clad aluminium wire voice coil with a diameter of up to 25mm. A longer voice coil copper wire can directly enhance transducer efficiency and drive capacity, improving transient response and resulting in purer, more comfortable sound. Each individual wire core in the ccaw coil has a diameter of approximately 0.035mm, as thin as a hair. Additionally, the ft1s voice coil frame employs lightweight ksv kapton, which also helps to significantly reduce the overall diaphragm mass. The result is enhanced response speed and minimized reverberation. Closed back design the ft1, as fiios first closed back over ear headphones, incorporates a variety of features that specifically enhance the closed back listening experience. A series of sound insulation components in the ft1 effectively reduce ambient noise, including external voices and environmental sounds, by up to 26db. Whether youre commuting, editing recordings, working in an office, or gaming, the ft1 allows you to immerse yourself in a high fidelity audio world. It is a truly great sounding, all rounder set of headphones. U shaped sound damping tube for enhanced noise attenuation the u shaped sound damping tube specifically developed for the fiio ft1 not only enhances passive noise attenuation but also allows sound energy to pass through a specific length and angle of the flute, increasing air viscosity and reducing cavity resonance frequency. This further enhances bass extension. Youll distinctly feel the air movement and the focused power of drums and strings. Conical baffle plate striving for excellent sound has always been the essence of hifi. The development team, based on the characteristics of the ft1 dynamic drivers, designed a conical baffle plate for it. This device allows the entire driver to be positioned parallel to the human ear, breaking up sound convergence and avoiding standing waves. As a result, there is minimal high frequency attenuation for truly hifi audio quality. 32omega high sensitivity design the fiio ft1 aims to provide users with a high quality hifi experience across various usage scenarios. To achieve this, the ft1 features a low impedance design of 32omega and boasts acoustic sensitivity metrics of 113db vrms1khz equivalent to 98db mw1khz. This significantly reduces the demand for driving ...
