FiiO FD15 13.8mm Magnalium DLC In-Ear Earphone

The FD15 from FiiO showcases a remarkable advancement in audio technology, featuring an array of cutting-edge innovations that redefine the standards of sound reproduction. At the heart of this headphone lies a 13.8mm large dynamic driver with a magnalium diaphragm and a DLC (Diamond-Like Carbon) gasket, creating a W-shaped independent suspension design that increases the effective vibrating area by 30% compared to conventional diaphragm designs of the same size.

Underpinning the FD15's exceptional performance is FiiO's patented F.T.B.S (Frontal Acoustic Prism "Tesla Valve") bass enhancement technology. Leveraging advanced powder metallurgy, this innovative acoustic design precisely calculates the branch length, angle, and quantity within the earcup cavity, resulting in a fluidic structure that matches the acoustic properties of the Tesla Valve. This engineering feat significantly enhances the headphone's ability to reproduce deep, resonant low frequencies, delivering a profound and immersive bass response that captivates the listener.

Complementing the FD15's cutting-edge acoustic prowess is its premium manufacturing quality and exquisite craftsmanship. The headphone features a 316L stainless steel shell, ensuring both durability and a sleek, premium aesthetic. The headphone cable, sourced from Furukawa's authentic imports from Japan, is crafted from Furukawa single crystal copper and Furukawa single crystal copper plated with silver, boasting a cross-sectional area as large as 22AWG, rivaling the quality of high-end HiFi headphone cables typically found in the thousand-dollar range.

The FD15's innovative approach to sound reproduction is further enhanced by its magnetic flux of 1.5T, which, combined with the magnalium diaphragm and DLC gasket, enables the headphone to faithfully reproduce the spacious and soft essence of "circle taste," while also achieving significant advancements in high-frequency extension and resolution. The result is a sound characterized by its bright transparency and refined delicacy, setting a new standard for sound reproduction.

Certified by Hi-Res Audio, the FD15 is the ideal choice for audiophiles who pursue unparalleled audio performance. Its groundbreaking features and exceptional craftsmanship promise to provide an immersive listening experience that exceeds expectations, redefining the boundaries of what is possible in the world of high-end audio.
