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.
