Fiio FA7s 6BA In Ear Monitor IEMs:


6 Knowles Balanced Armature Driver Units

FiiO FA7S adopts a multi-BA driver configuration featuring six high-performance balanced armature drivers on each side. It features HODVTEC-31618 set for an impactful lower end, RAD-33518*2 for a smooth, non-fatiguing treble response, and a custom-developed Knowles BA set for rich midrange response.

Professional Three-Way Crossover

FA7S is with three-way frequency crossover. Each frequency segment is handled by a set of two Balanced Armature drivers ensuring peak performance with lower interference with each driver. The pair maintains a 1:1:1 ratio between the drivers with 2 drivers for each low, mid, and high-frequency range.

High-Purity Cable

FiiO FA7S has a high-purity silver-plated monocrystalline copper cable. It consists of 152 wires made with 19 wires in 8 strands. Each wire is individually isolated and braided together with each other in a Litz pattern. It has angled MMCX connectors that help in a comfortable fit with the pair. Another attraction with this cable is the swappable termination plug design with FiiO's newly developed Twist-Lock technology.

3rd Generation Industrial Design

FiiO FA7S is made using high-quality stainless steel material with a powder metallurgy process. Each ear cavity undergoes PVD electroplating for improved rigidity. The face covers are crafted using a five-axis CNC machining process.
