FiiO FT13 Closed-Back Headphones (Natural (Red))

The FT13, like the FT1, features a massive 60mm dynamic driver, a size almost unheard of in its category. This larger driver generates more power and is more efficient at converting electrical signals into sound. The result is sound with less distortion, quicker transients, and deeper, more powerful bass. The headphone features a W-shaped diaphragm design inspired by speaker cones. Compared to the driver diaphragms typically found in headphones, this design increases the effective vibration area of the diaphragm by 25.8%. The diaphragm is made from a hard dome and a flexible surround. This rigid dome covers a larger surface area than traditional diaphragms, and since the voice coil drives it directly, there is less energy lost during vibration transfer. Compared to a more flexible material, the hard dome features reduced internal loss, resulting in higher efficiency and reduced distortion caused by driver breakup. Beyond the natural isolation of its closed wooden earcups, the FT13 features an integrated system of passive noise-reduction components. This includes a standing wave dissipation chamber, specially designed rear cavity sound-absorbing cotton, and a noise-reducing U-shaped tube. Together, these components can reduce everyday ambient noise by up to 26dB. This closed design also prevents sound from leaking out, making the headphones perfect for quiet environments like offices, libraries, or dorms without disturbing others. The FT13's impedance, sensitivity, and frequency response make it an ideal choice for listeners dipping their toes into the world of personal audio gear. It's a perfect match for mainstream, non-audiophile devices like smartphones, tablets, and PCs. Experience high-fidelity, audiophile-grade sound without having to invest in expensive or complex gear. Included are two types of ear pads, both featuring a skin-friendly, breathable, and durable outer material. Inside the earpads are low-density, slow-rebound memory foam that conforms to the shape of the ear. Compared to the artificial leather ear pads typically found on headphones, these offer an upgrade in both comfort and durability. Also included with the FT13 is four detachable audio plugs, allowing one cable to work with various kinds of audio sources. The FT13 features a Japanese-imported CCAW voice coil with an ultra-thin 0.035mm wire and a lightweight KSV former. These components dramatically reduce the moving mass of the diaphragm, resulting in faster sound response and reduced unnecessary reverberations. The voice coil has a diameter of 25mm. In a fixed magnetic field and with a constant current, a larger coil diameter means a longer voice coil wire. Thus, a longer copper wire results in greater driving force and higher efficiency, leading to a richer midrange and quicker transients. After extensive ergonomic testing, FiiO implemented a three-axis adaptive swivel that continues the tradition of excellent ergonomics on the FT series. This design not only ensures the headphones comfortably adapt to various head sizes and shapes, but also allows you to adjust them to ensure a perfect fit without sound leakage. A premium Yaoli linen storage bag is included with the earphones to further enhance the ownership experience. With materials and craftsmanship on par with premium French brands, its exquisite quality and excellent texture provide dedicated protection for your cherished device.
