FiiO FA19 Wired Earphone

For the ten balanced armature drivers FA19, we collaborated deeply with Knowles. Together, we built a custom enhanced bass balanced armature driver specifically for the FA19 to provide the listener with a deep low-frequency experience uncommon in multi-BA driver IEMs. Additionally, FIIO also worked closely with Knowles to optimize the mid and high-frequency drivers so that they not only sound highly detailed, but also pleasantly smooth. With the FA19 we carefully tuned all parts of the frequency response curve for a truly coherent and resolving sound.
