Fiio FA19 VS Fiio FH19

Youtube Video Summary

Fiio FA19 brings a premium feel: a sturdy, slightly translucent shell with visible BA packs, comfy fit, and a plush eight-wire cable that terminates in 4.4mm. The MMCX sockets aren’t ideal, but the shell is vented, holds tips well, and the magnetic case feels upmarket. Sonically, this 10-BA set leans warm-neutral with a rich, cohesive presentation—male vocals sound full, some female vocals come off a bit husky, and bass has quantity more than tightness. There’s a touch of 5–6 kHz energy and slight hiss; treble is clean and pleasant rather than showy. The bass switch mostly bumps mid-bass; the lower setting keeps things tidier. Overall it’s Fiio’s most well-rounded tuning to date, just shy of “exceptional” because of that soft mid-bass and a mildly flabby midrange.

Versus peers, FD15 sounds more neutrally tuned (if less special), while all-BA options like Supernova feel more natural and controlled down low. In the wider field, sets like Letshuoer Mystic 8 (a bit of a sleeper), ThieAudio Monarch MK4 (cleaner upper-mids, dual bass settings), ZiiGaat Luna (tighter, crisper for far less money), or even budget-friendlier picks such as YU9 can offer a stronger value proposition. At around $1,000, FA19 earns a solid recommendation for those who enjoy a warmer, airy BA take—graded roughly A4 / S-—but it’s a demo-first purchase and shines much brighter if found used around $300–$400. Not a new benchmark, yet a very good Fiio with treble finesse and a smooth, easygoing signature that many will simply enjoy.

Build and accessories are a clear win: a sturdy, comfortable, slightly translucent shell with MMCX connectors, a plush 8-wire cable terminating in 4.4 mm, and a premium magnetic case. As a 10-BA set around $1,000, it wears a tasteful black-and-silver faceplate and seals well without pressure issues. There’s a bass switch that nudges mid-bass upward; useful for taste, but not essential.

Sonically it’s a warm-tilted, cohesive presentation: male vocals come through full and rich, female vocals can sound a touch husky, and the mids avoid shout. Treble is clean and pleasant with a bit of 5–6 kHz energy that stays in check; overall clarity is good, though there’s slight hiss and the mid-bass can feel a little loose/flabby rather than tight. Stage and detail are solid, making this arguably one of FiiO’s better efforts, but the value is mixed—graded a strong A4 / S-: recommended if it suits the tonality, yet tough at retail amid fierce competitors; far more compelling on the used market or after a thorough demo.

Youtube Video Summary

The FiiO FA19 enters the kilobuck arena as an all balanced armature set that feels every bit as premium as its asking price, with a smoky clear resin shell, clean geometric faceplate and a generous accessory package that includes a modular cable, quality case and a wide tip selection. Comfort and fit are secure despite the driver count, with a manageable shell size, small nozzle and a build that looks and feels high end in daily use.

With the switch in the off position the FA19 leans neutral warm with bass slightly north of neutral, adding mid bass and low mid weight that brings extra richness to classic rock and other rhythm driven genres while staying reasonably controlled. BA bass dynamics and impact are a highlight here, coming surprisingly close to good dynamic driver sets and maintaining texture without obvious bleed, though the on position pushes additional energy into the low mids and can audibly soften midrange clarity. The upper mids and treble provide enough energy to keep vocals front and center and add air, shimmer and micro detail, walking a fine line where the presentation can feel lively and edgy at times but remains generally refined rather than harsh for most material.

On the technical side the FA19 delivers very good resolution, separation and depth, with above average stage size, accurate positional cues and a pleasing sense of weight and density to instruments and vocals that suits both rock and more spacious recordings like jazz and acoustic ensembles. It feels worthy of its price class and offers a distinctive, almost boutique tuning that can diversify a kilobuck collection without sacrificing overall naturalness, but that same character means it will not be the safest recommendation for every listener. Compared with more conventional all rounders such as Monarch MK3, RSV or Helios, FA19 becomes a conditional recommendation for those who understand and want its warmer tilt and energetic treble, ideally after a demo to be sure it aligns with personal preferences.

Youtube Video Summary

FiiO FH19 presents a neutral warm signature with a very complete package, combining a robust titanium and 7000 series aluminum shell, a soft high purity silver modular cable and a generous selection of tips, case and filters that feel genuinely premium.

With the black balanced filter the FH19 offers a neutral warm tilt, mid bass punch and sub bass extension that stay clean and controlled, giving male vocals and instruments extra weight while keeping bleed in check, and the midrange remains natural and full bodied, even if female vocals can sit a touch behind and the overall upper mids feel slightly relaxed compared with more energetic sets. Treble is smooth and free of harshness or sibilance, fitting the overall balance well, but those who crave more air past 10 kHz may find the FH19 a little restrained even on the green treble filter.

Technical performance is very good for this price, with above average soundstage, solid depth and layering, focused imaging and satisfying dynamics from the dual dynamic drivers, though micro detail and treble extension lag behind favorites like the SA6 EST, Xuanwu Gate or IE600. Overall the FH19 stands out as a very solid neutral warm option in the 600 dollar bracket for listeners who prioritize natural tonality and engaging bass over maximum air and detail.
