6 Knowles balanced armature drivers
A balanced armature uses a delicately balanced coil within a magnetic field to reproduce detailed sounds from across the frequency range. In the FA9, a HODVTEC-31618 dual-driver produces vigorous, authoritative bass with two subwoofers. An EJ-33877 dual-driver delivers natural, lush mids. And an SWFK-31736 dual-driver produces intricate, gentle treble. Combined, these drivers produce an ultra-clarified sonic experience.
3 sound adjustment switches
The FA9 features three sound adjustment switches on each IEM, allowing you to tailor the sound signature to your liking. It works by individually adjusting the impedance of the FA9’s drivers. Bassheads can dial up the low-end, neutral EQ lovers can keep things balanced, and experimental audiophiles can discover a sound unique to them.
Pro-grade 8-strand silver-plated copper wire
Copper and silver are locked in an eternal struggle for audiophile wire dominance. Silver is more conductive; copper is more resilient. With the FA9, FiiO has forged an alliance between these two metals, bringing you the conductivity of silver and the resilience of copper for a perfectly clarified sound that lasts.
