Fiio FA19 VS Thieaudio Origin

Youtube Video Summary

Fiio FA19 arrives as a true kilobuck treat, pairing monumental bass impact with high-end finesse. A 10-BA array (including custom bass drivers), a clever negative-feedback system, and an audio-grade crossover deliver deep, clean low end without clouding the mids—male vocals stay forward, natural, and ultra-clear. Up top, cymbal work has sparkle, air, and detail yet remains smooth and sibilance-free, while separation and layering feel studio-grade. At $1,000, this tuning reads as resolving, fast in attack/decay, and unmistakably fun.

For pure performance, the FA19 brings pinpoint imaging, beautiful depth perception, and a wide, well-ventilated stage that elevate both music and play. The bass toggle dip-switch can push sub-bass and mid-bass into downright addictive territory; switching it off reins things in for a more reference-leaning balance. Even against strong mid-tier contenders, micro-detail and retrieval step up a notch here—airy treble textures, subtle room cues, and layered backgrounds all come through with ease.

Competitive gamers get a standout edge: Valorant tracking feels “wall-hack” precise, Call of Duty benefits from immersive LFE without masking cues (especially with the switch off), and Rainbow Six Siege showcases clear vertical and positional info. The only caution is that the switch-on mode can be a touch sub-bass heavy in titles like Apex; otherwise this is an A-tier pick for the Wall-Hack Certified list—an analytical beast that blends clarity with grin-inducing punch.

Youtube Video Summary

Thieaudio Origin steps into the high end with a hybrid array—1DD + 4BA + 2EST + bone conduction—that pushes a richly textured, holographic presentation. The soundstage is wide and deep, imaging snaps into place, and the resolution clears the bar set by mid-tier sets. Most striking is the low-end: sub-bass digs deep with palpable rumble and impact yet avoids flooding the mix, leaving mids clean, detailed, and lifelike, and the treble airy with convincing cymbal sheen. At $850, the overall technical polish and bass quality feel appropriately premium—better than some kilobuck options.

For competitive gaming, the tuning translates across titles with ease. In Valorant, staging, separation, and distance cues deliver an A experience; occasional low-end bloom can introduce slight over/under flicks on sudden off-screen shots, but not often enough to dent performance. In Apex Legends, verticality and imaging impress (A-): during chaotic third/fourth-party fights, some lighter movement cues (slides, climbs) could cut through a bit more. In Warzone, depth and impact enhance immersion without masking key information, keeping imaging and separation strong. Tip rolling helps: foam trims bass and brightens; silicone restores slam.

Build and ergonomics match the sonic ambition: a galactic faceplate, sturdy 2-pin cable with swappable terminations, and a chassis that’s larger than average yet comfortable for long sessions (minor fatigue around the 6-hour mark). The nozzle is wide but short with a solid lip for secure tips. Overall, this is a fun yet precise set that excels in music and earns a high mark on a “wall-hack certified” style tier list for shooters—driven by standout bass, convincing staging, and top-tier separation.

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.

Youtube Video Summary

Thieaudio Origin brings a wild driver stack—1 DD + 4 BA + 2 EST + 1 bone conductor—inside a massive yet surprisingly comfortable shell. Build feels premium: striking faceplate, visible bone-conductor puck, proper nozzle lip, and a thicker cable than usual from the brand. The hockey-puck case is a nice touch, and for about $100 more there’s custom artwork available, making the unboxing and ownership experience feel a bit more special.

Sonically, this one swings for impact. Bass hits clean, strong, and fun, with upper mids that come across pristine. The trade-off: a hotter mid/treble band (around the 4–10 kHz region, with a notable 6 kHz glare) that can push cymbals and strings into an unnatural territory. Resolution and imaging don’t always keep pace for the price; stage is big and enveloping, but fine detail and separation can blur, making it a specialist that thrills on bass-centric tracks yet feels less convincing on metal or complex orchestral pieces.

Against its siblings, Origin sits like a more fun, bass-forward take compared with HYPE 4/10, but with a treble execution that’s less refined. Versus Oracle MK3, the latter’s ESTs sound crisper and cleaner; versus Monarch MKIII, that model’s tasteful 5–8 kHz dip lends better resolution. If pure detail is the target, sets like HiSenior Mega5 Bass or the Subtonic Annihilator may prove more satisfying. As a whole, Origin is a unique, bass-thrilled experience with excellent fit, huge space, and customization perks—great for those chasing visceral low-end and a cinematic stage, less ideal for listeners prioritizing treble finesse and microdetail at this tier.

Youtube Video Summary

Fiio’s FA19 brings a lavish unboxing at a $1,000 ticket: a premium case, a magnetic cable tie, cleaning and MMCX tools, and a mountain of ear tips (silicone sets, dual-flange, foams, full SpinFits, and HS18). The cable uses swappable terminations executed cleanly, though it’s a bit stiff, and the MMCX hardware rotates freely. The clear resin shells feel dense and well-finished, with a small nozzle and a medium fit that’s comfortable but not very secure—the MMCX rotation often requires a nudge to keep placement in the ear. Inside are 10 BAs per side and a tuning switch that Fiio markets as “monitor” vs “hi-fi.”

On the ear, FA19 reads as a warm, dense V-shape even in the so-called monitor mode. The switch simply means “more bass” vs “a lot of bass,” lifting the entire low end for thickness but yielding drone and blur rather than punch or texture—described as farty, flat-backed bass. Up top there’s sparkle, but treble control is lacking, pushing sibilance on vocals and cymbals; stage is fairly narrow and imaging unremarkable, though mid/upper-treble lift can tease out some vocal grain and breath. Against a key rival, the 64 Audio U4s (with M12), the Fiio feels outclassed: U4s offers tighter, better-balanced bass, a more neutral midrange, and non-fatiguing treble with enough extension to stay lively. Verdict: despite stellar accessories and build, FA19’s tuning and technicals don’t justify its price; not recommended at $1,000—and there are stronger options even far cheaper.

Youtube Video Summary

At $850, Thieaudio Origin positions itself as an unapologetic bass icon with a complex driver stack (1DD/4BA/2EST plus bone conduction). Build and accessories are a mixed bag: the large, chunky shells will be too big for many ears, and the semi-transparent, pattern-heavy faceplates feel a bit generic. The thick stock cable suits the heft but the swappable plug mechanism is long, doesn’t lock, and often detaches at the adapter rather than the jack—an unnecessary annoyance. Fit is the major caveat; for smaller ears, contact is mostly at the tip, which compromises comfort and seal consistency.

Sonically, Origin is unmistakably bass-forward—well beyond Harman—with a warm, thick low end that initially reads as overbearing and soft on definition. With time, that bass takes on a distinctive, “ooey-gooey” atmospheric quality that sits under the mix rather than congesting it, enabling a surprisingly grand, spacious presentation. Above the lows, the tuning is “new-meta” adjacent: neutral-ish mids, balanced upper-treble, and a touch of mid-treble bite that sharpens transients and adds contrast. The trade-off is occasional edginess/sibilance on certain vocals, but guitars and percussion benefit from extra snap. Live recordings in particular gain scale and drama.

Against the Mega 5 EST Bass+ (cheaper, similarly boosted), Origin offers better separation and more engaging transients, while the Mega feels sludgier and less distinct—though also less edgy. Overall, Origin is a unique bass experience that prioritizes mood and scale over textbook bass tightness. The combination of fit challenges, polarizing low-end quality, and treble bite tempers enthusiasm, settling at a three-star (out of five) verdict—compelling for bass lovers seeking something different, but not a universal recommendation.

Youtube Video Summary

Thieaudio Origin goes full mad-science: 1DD + 4BA + 2EST + bone conductor (eight drivers per side), big shells, hefty stock cable, and a tuning built around a ~12 dB sub-bass shelf. Fit can be a touch chunky, but foam tips (think Render) lock in seal and turn the low end from “more bass somewhere” into deep, anchored slam; silicone leaves it a bit loose. Accessories are barebones—swap plugs, tips, case—and that’s it. No fancy gifts, just a box of sound.

Sonically it’s a deconstructed presentation: instead of one smooth ribbon like a single DD, the Origin spreads the band across space—drivers carving out their lanes so instruments pop up here… then there… then over there. It’s not “mushy blend,” it’s forcible separation that can feel museum-exhibit surreal: treble details flit around (hello ESTs) while bass feels omnipresent and room-filling. It doesn’t really scale with amps; neutral DAC/amps to pricier rigs all keep roughly the same character. What can change the tonality is cable impedance—at 9 Ω and high sensitivity, cheap/high-resistance wires can skew things, so stick with a stout low-impedance lead.

Gripes? The cable is thick, custom faceplates up the bill, and the package isn’t exactly a Santa sack. But for $850, the payoff is a unique, spacious, “pulled-apart” soundstage that turns playlists into set pieces. Not for purists chasing one-driver cohesion; absolutely for listeners who crave clarity, staging theatrics, and tactile bass. Final word: a solid 9/10 on sound and swagger—price keeps it off the throne, excitement keeps it in the cart.

Youtube Video Summary

Thieaudio Origin takes the “Meta” idea and dials it toward a fuller, bass-forward presentation without losing control. The bone conduction driver is not a gimmick—low notes carry palpable vibration and reverb while staying tight with clean layering and no mid bleed. Vocals sit naturally—neither shouty nor buried—though this isn’t a vocal-focused set (reach for RS5 if that’s the priority). Versus Oracle Mk II, the Origin trades some cleanliness for deeper tactility and weight, making bass textures feel more alive.

The top end is airy and extended on smooth Sonion ESTs, cutting through the warmth to balance the tuning. Most tracks are fine, but snare- and cymbal-heavy songs at higher volumes can push the treble into fatiguing territory (e.g., around 3:30 in Hikaru Utada’s “Time”). It’s generally controlled at moderate levels; just note that treble energy scales and can turn sharp when cranked.

In A/Bs, the Origin’s bass texture outclasses sets like Mega 5 EST, offering more detail, impact, and less boom. Against TITAN, Origin’s reverb and low-end “shake” edge it out while avoiding the Titan’s 5 kHz peak—though Titan still feels more exciting with livelier vocals. Versus all-rounders Monarch Mk II and Hype 10, those remain cleaner with better mids/layering but can’t match Origin’s sheer bass depth. The wildcard is BAJIE: stock, Origin wins; with EQ, BAJIE’s bigger 14.2 mm driver slams harder, while Origin stays the more balanced, tactile choice. Net: for a premium, fun, bass-centric daily driver under a grand, Origin sets a new reference—unless maximum slam with EQ is the goal.
