FiiO FD15 13.8mm Dynamic Driver In-Ear Monitors – Racing Silver
The FiiO FD15 is a high-fidelity single dynamic driver in-ear monitor built around one of the largest drivers in its class: a 13.8mm Magnalium (aluminum-magnesium) diaphragm with a diamond-like carbon (DLC) gasket. The result is powerful, authoritative bass, a natural and balanced midrange, and smooth, extended treble — all from a single, coherent driver.
Housed in hand-polished 316L stainless steel shells and paired with a premium hybrid silver and Furukawa monocrystalline copper cable with swappable 3.5mm and 4.4mm plugs, the FD15 delivers a complete audiophile package that is easy to drive from phones, dongles, and portable players.

- 13.8mm large dynamic driver with Magnalium diaphragm and DLC gasket
- W-shaped driver suspension increases effective vibration area by about 30%
- 8.6mm long voice coil and external 1.5T high-flux magnetic circuit
- Patented “Tesla Valve”-inspired bass enhancement acoustic design
- Frontal acoustic prism with adaptive phase adjustment for smoother highs
- 316L stainless steel shells with PVD finish

Big Driver, Big Dynamics
With nearly twice the effective area of a conventional 10mm driver, the FD15's 13.8mm driver works less hard at any given volume, delivering effortless dynamics, deep low-end extension, and low distortion.
