FiiO FH5 Quad Driver Hybrid In-Ear Monitors (IEMs)


Just like the exotic cars which inspired them, the FiiO FH5 IEMs offer a high-end, exclusive experience for a discriminating audience. 

1 10mm Dynamic Driver for Bass

Dynamic drivers are the most common type of driver in the world. They reproduce booming bass at a low price tag. However, they don’t produce mids and trebles as adeptly as other drivers, and when pushed too hard they’re known to create harmonic distortion. This is why the FH5 PRO delegates only bass frequencies to the dynamic driver. 

1 Balanced Armature for Mids 

A balanced armature uses a delicately balanced coil within a magnetic field to reproduce detailed mids and highs. The FH5 delegates mids to a Knowles ED30262 balanced armature to create a rich palette for vocals, guitars, and other instruments. 

2 Balanced Armatures for Highs and Ultra Highs

The FH5 uses two Knowles 31082 balanced armatures for the precise reproduction of intricate high and ultra-high treble frequencies. By allocating each frequency to different drivers and armatures, the FH5 achieves a sonic richness that has to be heard to be believed. 

3 Sound Tubes 

What’s the point of separating sound frequencies to four drivers if you’re just going to blast them all out of the same sound tube? That’s the question that led FiiO to employ three sound tubes--one for bass, one for mids, one for highs--in the FH5. This feature maintains frequency separation, bringing you an addictively unique sonic experience. 

Pro-Grade 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 FH5, FiiO has forged an alliance between these two metals, bringing you the conductivity of silver and the resilience of copper, all housed in an environmentally-friendly TPU sheath.
