Rich and Powerful Lower-End Response:-

With four dedicated lower-end customized Knowles BA drivers, FiiO has aimed for a strong and powerful bass response with the FA19. Engineers have creatively made the use of 3D-printed ear shell technology to craft the shell that helps to guide the strong lower-end energy into the rear cavity. This is known as negative feedback bass enhancement technology. This technology greatly improves the lower-end of the pair promising a strong rumble in the sub-bass region and a fast, snappy mid-bass section.

Scientifically Designed Mid-Frequency Notch Filter:-

FiiO FA19 features a scientifically designed mid-frequency notch filter. This results in a smooth mid-frequency response promising a refined sound reproduction in both midrange and treble regions. This enhances the mid-range with better clarity and resolution for both vocals as well as instruments. This notch filter helps enhance the midrange performance by eliminating sibilance and a refined transition into the high frequencies.

Professionally Designed Electronic Crossover:-

In order to get the best performance out of each driver unit, the FiiO KA19 features professionally developed electronic as well as physical crossover. The electronic crossover here features high-quality Rubycon audiophile-grade capacitors. They boast exceptional precision, with an impressively low error tolerance of 0.1%.

Two-Mode Tuning Switch:-

FiiO FA19 allows you to choose between two carefully adjusted tuning modes with the pair. It has a two-way switch that provides two tuning options, HiFi tuning and Monitor Tuning. The Monitor tuning has a clean, detailed sound for people into music production and editing, the HiFi mode is designed for audiophiles with richer bass and midrange performance.
