FiiO FA7s 6 Driver Balanced Armature

FiiO FA7S adopts a multi-BA driver configuration featuring six high-performance balanced armature drivers on each side. FiiO has partnered with Knowles to design high-quality BA drivers for the FA7S. 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.

Precise Performance With Professional Three-Way Crossover:-
FiiO has arranged the drivers in FA7S in a 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.

Top-Quality Cable For Top-Quality Performance:-
Cables play an important role in HiFi audio. FiiO has bundled the flagship FA7S with 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 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 has redesigned the ear cavity structure for the "FA" series. They now feature a 3rd gen industrial design similar to the "FD" series of single dynamic driver earphones by them. The pair 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.
