Thieaudio Monarch Mk2 VS Symphonium Titan

Youtube Video Summary

Symphonium Titan delivers a bass-centric tuning that keeps its house in order. The mid-bass is tactile and textured with satisfying slam, while the sub-bass reaches deep, rumbly, and clean. Crucially, vocals remain clear and the treble is well-extended without harsh peaks; there’s a small 5–8 kHz rise that adds excitement and “snap,” yet overall control prevents bleed into the mids. The stage feels big and open, and the set avoids excessive warmth, making it a genuinely balanced bassy IEM.

There is a caveat: that 5–8 kHz lift can come off a bit sharp on forward-snare or energetic K/J-pop and hip-hop tracks, so the Titan shines best at mid volume rather than cranking it. Even so, it stays smoother than options like Maestro/Scarlet Minis, offering better extension and less fatigue while keeping the fun. Scaling is above average, and the overall presentation remains engaging and authoritative.

In comparisons, Titan reads as a direct upgrade to Monarch Minis (bigger stage, less fatiguing), more balanced than Scarlet Minis (which chase sheer slam), and a far better value play than Grand Maestro or EVOs for low-end lovers, thanks to cleaner bass and tamer upper mids. For warmer, smoother needs, DUNU’s take is fuller but not as rumble-clean or open. Under $1,000, Titan sets a new benchmark for bass-heads who still want clarity, air, and control.

Build & fit: Premium presentation with a handsome “lava” faceplate and a cloth-sheathed cable featuring swappable terminations—useful, but the connector is bulky enough to be unwieldy. The shell itself is very large and can be tricky for many ears, affecting seal and even bass response. Comfort and security are not strong suits. Tip rolling helps; AZLA AirFit Light tips improved seal and tamed occasional treble bite.

Sound: A neutral, mid-forward tuning with a tasteful sub-bass lift, clean lower treble, and excellent extension. Midrange detail pops with fine micro-contrast, while treble remains smooth—evoking that easy, HD600-like effortlessness. Stage is wide with standout imaging and layering. The trade-off is a lean lower-mid/mid-bass region (that “Harman dip”), which can make non-bass-heavy music feel a bit dry and clinical, reducing perceived depth and visceral impact.

Comparisons & verdict: Versus Moondrop’s stable, Blessing 2 still offers a fuller, more linear low end and remains the more all-round pick; S8 brings superb treble and mid detail with similarly lean bass; Campfire Aura dazzles with holographic imaging and surprisingly satisfying BA bass, though its tonality is quirkier. Monarch MKII earns a solid 4/5 for tonal balance, resolution, and imaging—but the size/fit caveat is serious, and the lean bass means it won’t dethrone Blessing 2 for those craving warmth or body. Demo first; if it fits and that crisp neutrality appeals, it’s a fantastic listen.

Build & accessories: Compact shell with a slightly old-school shape and flat 2-pin connectors, secure fit, and a nozzle some may find a bit much. The package includes Thieaudio’s large, sturdy case, multiple tips, a cleaning brush, and a fabric-sheathed stock cable with a solid chin slider and a durable Y-split. The cable’s modular plug system (2.5/3.5/4.4) locks in confidently and feels well made.

Sound: a neutral foundation with a dash of fun—clean upper mids, tasteful sparkle, and tight, articulate bass. Unit variance shows on graphs (his sample reads a bit bassier with slightly more treble vs other measurements), but the core tuning stays intact: rich mids, smooth presence, and airy extension that present music as natural, wide, and open. Versus Monarch MKIII, this MKII feels less bright and less fatiguing, with fuller mids. Compared to Annihilator 2023, MKII is flatter and more even (Annihilator hits harder and has a 10k zing some hear as “fake”). Against Lime Ears Tera, MKII is a touch warmer and easier; versus the pricier Europa, it tracks similarly on paper but wins on comfort and value; and it offers more body than budget darlings like Hexa, which can come off lean.

Verdict: a high-tier all-rounder prized for midrange timbre, air/detail, note weight, and imaging. It reads neutral-natural with just enough excitement to stay engaging over long sessions. Personal taste and fit still matter—always demo if possible—but within this preference space, Monarch MKII remains a special, well-balanced choice that continues to earn its spot among top IEMs.

Thieaudio Monarch Mk2 stays a top-tier pick by balancing excellent tonality with solid, price-appropriate technicalities. The tuning sits close to the current meta, with a slight dip in the lower mids and a noticeable 6 kHz emphasis that adds sparkle and energy. It’s the “spice” to the Mega5-EST’s plain water—still coherent and controlled, but with extra fizz that makes music feel lively. While resolution doesn’t chase the extremes of Elysian Annihilator or Softears RS10, within the $999 bracket the performance remains compelling, making it an easy recommendation among kilobuck IEMs.

Build and accessories are straightforward: a full-resin shell with metal nozzle, a cloth-sheathed cable featuring interchangeable 3.5 / 2.5 / 4.4 terminations, and a proper case with silicone and foam tips. The fiery orange faceplate is the sole colorway. The catch is fit—the shell is large, and for smaller ears that can be a deal-breaker; no sound quality matters if it won’t seal comfortably. For those wanting a near-perfect meta hit with less treble spice, Hisenior Mega5-EST is noted as the safer tonal bullseye.

Choose Monarch Mk2 if a slightly V-leaning, meta-aligned tuning with engaging upper-presence appeals, and if the ear geometry can handle the chunky shell. Skip it if chasing max detail retrieval above all else, craving a more pronounced V-shape (consider Monarch Mk3 instead), or if fit is uncertain. The overall verdict: impeccable tuning paired with good—if not summit—technical chops keeps Monarch Mk2 at the top of the ranking conversation without needing boutique pricing.

Youtube Video Summary

Symphonium Titan shows up with a big box, a blue theme, and a cable that feels too soft for a $1,000 set, plus a hefty metal case that could double as a tiny sarcophagus. The shell styling reads plain, almost like a stickered faceplate, and the accessory pile is fine-but-forgettable. The headline spec, though, is the eyebrow-raising 3Ω impedance—a choice that can stress amps, make cable impedance matter far more than it should, and generally feels needlessly risky when series/parallel options and crossover tweaks exist. Swapping cables doesn’t fundamentally rescue it; the blue stock wire is comfy but uninspiring in hand, and tip-rolling doesn’t unlock anything magical.

Sonically, Titan delivers a tidy, punchy kick drum and then coasts. It comes across as an all-BA tuning that’s overly polite: narrow soundstage, very neutral demeanor, vocals that sedate rather than seduce, and detail that never reaches “crystalline.” The sensation is like a go-kart with a limiter—foot down, waiting for excitement that never arrives—leaving the set short on engagement or a defining “thing” that justifies the price. Across amps—tube pre, solid-state, speaker-ish outputs—the character stays the same: controlled bass thump surrounded by music that refuses to wake up. In a world where a $21 budget set can spark a grin, Titan’s ultra-safe tuning and 3Ω quirk make it more “why?” than “wow.”
