Thieaudio Monarch Mk2 VS Hisenior Mega5-EST

Youtube Video Summary

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.

Hisenior Mega5-EST brings a tidy, understated shell with a semi-custom fit that sits secure and comfortable on medium-small ears. The box is loaded—foam and silicone tips, a microfiber cloth, and a chunky Pelican-style case—but the included cable is a mixed bag: it looks great and handles well, yet comes only in 4.4 mm balanced, which will annoy single-ended users. Build is clean, nozzle a touch long for a slightly deeper seal, and overall ergonomics feel sorted.

Sonically, this is top-tier tuning. The FR hugs a neutral target with a tasteful sub-bass lift under ~150 Hz, midrange sits right where it should, and treble is polite rather than hot. The result is a warm-neutral, low-contrast presentation that’s easy to listen to for hours with solid imaging and separation plus a nice sense of front-to-back depth. The trade-off: initial transients don’t bite—bass and string attacks are clean but not snappy—so the technical “zing” is more good than great.

Against peers around $550, Mega5-EST slots between flavors: DUNU SA6 is warmer and sparklier up top but softer through the mids; Yanyin Canon 2 delivers chunkier, more physical bass and standout vocal texture; and Moondrop × Crinacle Dusk (on its analog cable) sounds cleaner, more clinical, with sharper bass attack and a tick more resolution. As a daily-driver tonality, Mega5-EST is excellent—the kind of curve that just feels “right”—held back only by middling incisiveness. Verdict: a solid 4/5 for sublime tuning, ergonomic ease, and relaxed refinement, with the caveat of the 4.4-only cable and merely moderate macro-dynamics.

Youtube Video Summary

Mega5-EST (Bass Edition) shifts the original’s polite profile into a fuller, more satisfying listen. It keeps the smooth, relaxing, inoffensive tuning of the OG but adds extra oomph and slam down low, coming across warmer and bassier without mid-bass bleed or muddiness. Separation and microdetail take a small hit versus the cleaner, “vanilla” OG, yet the payoff is a more musical, comforting tonality that grows with time—great for R&B and jazzier sets. Upper-end extension is present and airy from the ESTs, but it’s subtle rather than sparkly; vocals and treble don’t jump out, they sit naturally in a well-balanced mix.

Where it flexes in tonality, it yields some ground in technicalities. The bass has proper quantity and impact, but texture and tactility are a touch smooth versus fresher peers that sound quicker and more resolving. If a laid-back, cohesive presentation is the goal, this tuning makes sense. If the wish list includes bigger dynamic contrast and crisper detail retrieval, options like recent hybrids and tribrids push ahead in separation, control, and bass definition.

Value is the sticking point. At around $600, compelling alternatives undercut or outclass it: budget-friendlier hybrids offer tighter low-end texture and more engagement, while mid-tier tribrids (e.g., Oracle MK3) bring cleaner balance, better bass control, and an overall resolution lift—even if they’re not as overtly bass-forward. For listeners craving a comforting, slightly warm, and easy signature, Mega5-EST (Bass) is genuinely enjoyable. For those chasing technical performance per euro, similarly tuned sets like K4-style isobaric DD hybrids or punchier tribrids present a stronger case.

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.

Youtube Video Summary

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

Hisenior Mega5-EST (Anniversary Edition) hits with a rare mix of slam and finesse: a single DD + 2BA + 2EST that pours out a chest-pressing low end yet keeps the mids and treble startlingly natural. The magic is in the space—not fake wide, but convincingly three-dimensional, with instruments stepping forward, drifting back, and snapping into place. Tracks that should sound “live” actually feel like a venue, with reverb and air rendered uncannily well. Call it “neutral” if the graph says so, but the tuning is exciting, never sleepy, and it scales from an affordable dongle/amp to tubes without losing its character.

Build and kit are delightfully weird in the best way: the cable is a stout two-wire with fixed 4-pin hardware, the case is hilariously oversized (and oddly practical), and the box stuffs in a mountain of tips—foam and multiple silicone sets—so fit is basically guaranteed. Cosmetic quirks (“Febos” branding on the shells, Anniversary shells looking plainer than the regular version) are the only eyebrow-raisers. None of it matters once the music starts: the imaging is knife-sharp, dynamics pop, and that sub-bass rolls in like weather.

At around $550—aka Moondrop Variations money—this thing doesn’t just trade punches; it outperforms for the same reasons Variations became a benchmark, then adds more body, more staging, more goosebumps. The verdict is not coy: this is a straight 10/10, the kind of IEM that makes changing tracks feel painful because the current one sounds too good to leave.

Youtube Video Summary

Hisenior Mega5-EST arrives with a polished package, a rugged Pelican-style case, and plenty of tips. Comfort is excellent for long sessions. Sonically it favors an even-keeled, natural presentation with a touch of warmth down low. Bass has punch without the heavy, resonant sub-bass of its Dunu counterpart, which helps detail come through. The midrange is smooth and clear, vocals sit naturally, and treble offers good extension without fatigue. The big talking point is stage and imaging: the Mega5-EST throws a wide soundstage with strong layering and separation, though it’s a little more relaxed in focus than sets that push elements forward.

For competitive play the tuning is a mixed bag. In Apex Legends, the stage can feel so wide that subtle cues get a bit distant, and occasional low-end punch can blur separation during chaotic fights—performance sits around a B to B-. In Call of Duty it scores about a B- as well: immersive and impactful, but long-range tracking and lighter taps demand more effort. Valorant fares better at roughly a B, where gunfire pierces the mix and footsteps carry decent depth on tighter maps. Overall, Mega5-EST is a non-fatiguing, musical IEM that shines for music and general entertainment, and rates a B- on the Wall-Hack Certified tier list for competitive gaming.
