FiiO FH19 2 Dynamic 6BA Hybrid In-Ear Monitors
Overview
The FiiO FH19 is a hybrid in-ear monitor with eight drivers per ear: a push-pull dual dynamic driver set for bass and six Knowles balanced armatures for the mids and treble. It's FiiO's flagship hybrid, built for listeners who want deep, controlled bass and fine detail from the same pair of earphones, with three swappable filters to fine-tune the sound.
The push-pull bass unit, co-developed with Tokyo Onkyo in Japan, pairs two 13.7mm dynamic drivers with PU+DLC composite diaphragms facing each other. Because the two drivers work together, each needs only half the movement to reach the same volume, which keeps distortion low and bass clean. Four custom Knowles mid-range balanced armatures and two Knowles SWFK treble armatures handle the rest, in a four-way acoustic design with Rubycon audiophile-grade film capacitors in the crossover. FiiO's mid-frequency notch filter removes an 8kHz peak from the mid drivers to cut sibilance.
The shell combines 7000-series aerospace aluminum with a pure titanium midframe, keeping each earpiece to about 12g. The semi-open design relieves pressure for a relaxed, wide-sounding presentation. It ships with a pure silver Litz cable (8 strands, 224 wires) with expanded MMCX connectors and swappable 3.5mm and 4.4mm plugs, an HB7 carrying case, and a wide range of ear tips including SpinFit, HS18, and HS20.
Simcoe Audio Video Insight
The FH19 is a strong choice if you want hybrid bass weight without giving up treble detail. At 16 ohms and 109dB/mW, it's easy to drive from a phone dongle, portable player, or desktop DAC/amp. The green filter comes installed; the other two live in the carrying case, so try each with music you know well before settling on one. Use the 4.4mm plug with a balanced source for the cleanest results.

Buyer's Guide
Who It's For
- The Detail-and-Bass Listener: Wants full, controlled bass without losing treble clarity.
- The Tuning Experimenter: Wants to adjust the sound with swappable filters.
- The Balanced-Source Owner: Has a 4.4mm player or DAC and wants a premium cable included.
How It Compares
The FH19 builds on FiiO's FH9, keeping its semi-open design and coaxial treble layout but replacing the bass and mids with a push-pull dual dynamic unit and custom Knowles mid-range armatures. If you prefer an all-balanced-armature sound, compare it with the FA19.
