■Newly developed 13.8mm dynamic driver significantly improves expressiveness
・The FD15 is equipped with a newly developed 13.8mm dynamic driver with a larger diameter. Compared to the previous model FD5, the effective vibration area of ​​the diaphragm has increased by approximately 40%, improving the conversion efficiency from electrical signals to air vibrations. This has resulted in a significant improvement in the overall expressiveness of the sound, a rich sound field, and high clarity in the mid-range.

■High-quality sound design with magnalium diaphragm and powerful magnet
・The driver newly adopts a diaphragm made of magnalium (magnesium-aluminum alloy), which is lightweight yet rigid. The gasket uses hard DLC (diamond-like carbon) to expand the effective vibration area by 30%, providing a stronger and more faithful sound to the original sound. In addition, a powerful magnet with a magnetic flux density of 1.5 tesla and a large voice coil with a diameter of 8.6 mm enable powerful and delicate driving, achieving both strong bass and excellent high-frequency resolution.

■Ideal acoustic characteristics and enhanced bass range

- Inherits the "Acoustic Prism System" that adjusts the phase of the high range and improves overall diffusion. In addition, the newly developed patented technology "F.T.B.S" is adopted to achieve both deep bass and delicate expression. The precisely calculated housing shape significantly reduces unnecessary resonance and internal reflection of sound, enabling precise music reproduction that is faithful to the original sound.

■User-adjustable sound control

- Two sets of red and black interchangeable sound guides are included. Red emphasizes the bass range and vocals, while black emphasizes the treble range, with more delicate and clear characteristics. This allows you to personalize the sound according to your preferences and sound source.

■High-quality design and standard included cable

- The housing is made of highly durable surgical stainless steel 316L, which is also used in medical equipment, and is hand-polished and coated to achieve both luxury and beauty. Ergonomic attention to detail provides an optimal fit.

・The standard cable is a 480-core cable made of Furukawa Electric's mixed single crystal copper wire and silver-plated single crystal copper wire. It is compatible with 3.5mm/4.4mm interchangeable headphone plugs, and achieves extremely pure music signal transmission.
