FiiO FA19 10 Knowles BA Driver IEMs, a groundbreaking masterpiece in the realm of in-ear monitors (IEMs). Engineered with precision and passion, the FA19 redefines the standards of multi-BA driver IEMs, delivering an unparalleled auditory experience that will elevate your listening sessions to new heights.

At the heart of the FiiO FA19 lies a symphony of sound, meticulously crafted through a collaboration with Knowles, a pioneer in acoustic technology. With a total of 10 custom Knowles balanced armature (BA) drivers per ear monitor, including 4 dedicated to enhanced bass, 2 for rich mid-range, and 4 for sparkling treble, the FA19 ensures every note is reproduced with breathtaking clarity and accuracy.

The FA19's bass performance is truly exceptional, thanks to the innovative negative feedback bass enhancement system. Developed by FiiO in conjunction with Knowles, this system harnesses the power of four custom-enhanced bass BA drivers per channel to deliver deep, thunderous bass that resonates with visceral impact. Utilizing precise DLP 3D printing technology, the FA19's shell is designed to optimize bass delivery, resulting in a bass response that reaches unprecedented depths.

But the FA19 is not just about bass—it's about achieving a harmonious balance across the entire frequency spectrum. With a smooth mid-frequency curve facilitated by a specially designed notch filter, the FA19 ensures that even the most demanding listeners will be captivated by its clarity and resolution. And with audiophile-grade crossover capacitors from Rubycon, every musical nuance is faithfully reproduced, offering enhanced high-frequency resolution without sacrificing tonal finesse.

Designed for audiophiles and professionals alike, the FA19 features FiiO's patented S.Turbo acoustic design, which optimizes the transition between low and mid frequencies for a cleaner, purer sound. And with the ability to switch between Monitor and HiFi modes on the fly, the FA19 offers versatility and flexibility for any listening environment.

Completing the package is a high-purity pure silver cable, meticulously crafted for stunning sound quality. With 224 individually insulated wires twisted in a Litz structure and encased in transparent eco-friendly TPU, the cable not only enhances the FA19's appearance but also ensures durability and longevity.

In summary, the FiiO FA19 is more than just an IEM—it's a testament to the pursuit of sonic excellence. Whether you're a discerning audiophile or a professional musician, the FA19 will transport you to a world of pure, immersive sound unlike anything you've experienced before.
