A whole new level of sound, 6 Knowles BA driver custom setup

The 6 Knowles BA drivers per ear, together with the carefully-designed 4-way
crossover and low-frequency ultra-long sound tube, completely covers the
entire audible frequency range with a sound that will take your breath away.

More lifelike sound than ever, Custom Knowles EJ BA driver

The FA9 marks the first time FiiO has employed Knowles EJ balanced
armature drivers, commonly used among high-end IEMs. FiiO and Knowles
collaborated to come up with the custom EJ-33877 driver for use in the FA9
for excellent mid-frequency performance with hauntingly realistic vocals.

80.6mm ultra-long sound tube, Specially-designed acoustic filter

In order to achieve the purest sound performance and to ensure the multiple
drivers do not interfere with each other, the FA9 employs a specially-
designed, ultra-long sound tube 80.6mm in length. The sound tube acts as a
low-pass filter that effectively filters out unneeded extra mids and highs
from the drivers to ensure a seamless frequency response. The sound tube also
ensures the mid-bass is smooth and clean while enhances bass texture in
general.

Four-way crossover, Igniting a fire within your heart

The four-way crossover design has been applied so that each driver works
perfectly in harmony with each
