Xenns Tea Pro VS ThieAudio Monarch MK4

Xenns Tea Pro lands with the familiar “Tea” swagger: a baby-blue, sparkled shell that looks subdued but premium, a modular 3.5/4.4 cable that clicks together more cleanly than most, and the infamous ultra-soft pouch (yes, the “chinchilla” one). Build is hefty yet comfortable, with a tiny ear “shelf” that doesn’t poke and giant L/R markers that actually help. Inside is an 8-driver stack—2 dynamic + 6 balanced armatures—priced around $360, right in the historic Tea lane. Wide-bore tips can make the upper range shouty, but switch to foams or X-Elastic and the tuning snaps into place: smooth, powerful, and deeply satisfying.

Sonically it’s the sports car that rides like a chaise lounge: speed and detail on tap, but with the warmth dialed up ~20% so long sessions feel luxurious. Bass reaches low with a tactile rumble that sneaks up in tracks, mids are rich and present, and treble is tastefully shaved to avoid glare—energy without edge. The stage isn’t stadium-wide; instead it’s an immersive “pressed-in” bubble that places the orchestra around the head with excellent instrument presence and macro-dynamics. It carries the Tea/T2 lineage forward by focusing less on sterile “detail points” and more on excitement and physicality—music shoved into the ear in the most pleasurable way. Verdict: an unabashed 10/10 crowd-pleaser in its bracket and a default recommendation—pop on the 4.4 plug, use the right tips, and let it cook.

Xenns Tea Pro lands as a confident mid-tier contender with a 2DD+6BA setup around $350–360, going head-to-head with sets like DaVinci, Estrella, and Dusk. Sub-bass has real grunt—808 drops, the 38 Hz hit on Big Boi’s “Kill Jill,” and early-2000s hip-hop cues slam with authority yet stay controlled. Electric-bass lines have clean pluck and release, avoiding mid-bass bloom, so the low end never muddies male or female vocals; the tuning plots close to a favored target without sounding sterile.

The midrange keeps vocals center and natural—no husky haze from mid-bass, no shout from upper-mids—and treble carries harmonics without tizzy edge, handling tricky voices (think Neil Young, Elton John, Jim Croce) with ease. Fans of the Moondrop Variations’ leaner, drier 3 kHz-pushed profile may find the Tea Pro richer and less “etched,” but that extra body reads as musical rather than bloated. Crucially, the BAs avoid that metallic tinge, giving cymbals and keys a clean, pleasing sheen.

On balance, this is the kind of tuning that competes directly with its peers—and depending on priorities, arguably beats them. With punchy sub-bass, stable mids, smooth but detailed top end, and zero fatiguing quirks, the Tea Pro sits between a firm “would buy” and a potential “shameless hype” slot—prime material for renewed top-five shortlists now that the market has cooled.

Build & presentation scream premium: a matte metal alloy shell with lush green-blue fade and gold script, plus a black-silver sparkle faceplate that looks like wearable art. Ergonomics are excellent despite a slightly wider nozzle and a bit of heft, allowing long sessions without discomfort. The package impresses with a gallery-style unboxing, matching carrying case, and a silver cable with interchangeable 3.5/4.4 terminations. Under the hood: 2 dynamic drivers + 6 BAs at ~$360.

Tonally it’s a balanced, warmer-leaning set with elevated sub-bass depth, clean attack/decay, and more treble extension and sparkle than comparable sets. The stage sits a touch more intimate, but separation and layering are immaculate, and imaging locks in with precision. Mids don’t pop as forward as some peers, yet overall resolution stays high with “oodles of detail,” giving music a rich, cohesive presentation that still feels highly detailed.

For competitive play the performance is A-tier: in Apex, Valorant, and especially Call of Duty, imaging and depth perception are master-class. Gunfire comes through cleaner with less reverb; airstrikes and mortar noise get pushed back so crucial cues like footsteps, slides, and shield pops cut through. The more intimate stage aids crosshair placement and micro-positioning, while separation stays clear even in chaotic fights. Verdict: a high A- on the Wall-Hack Certified list—an excellent pick for gamers wanting warmth, sub-bass authority, and elite imaging without sacrificing musical enjoyment.

The Xenns Tea Pro stands as the most refined and well-rounded iteration of the Tea series to date, offering strong competition in the $300 IEM market. While it loses some of the unique "sauce" found in earlier models, it delivers significant improvements, particularly sounding like a "better Da Vinci" with its bass presentation. The Pro features a similar heaviness and thickness to the notes but adds more upper mids, treble extension, and overall better resolution. For roughly $60 more than the Da Vinci, the Pro offers upgraded drivers from Knowles, contributing to better timbre, a bump in technical performance, and equally good accessories.

Compared to the original Tea and Tea 2, the Pro emerges as the better all-rounder but lacks their distinct character. The original Tea remains superior for its highly addicting vocals, bite, and holographic staging, while the Pro offers more balanced, fuller, smoother, and more versatile vocals alongside superior bass in slam, texture, impact, resolution, and rumble due to its new dual dynamic drivers. Treble extension, overall resolution, and a more open stage also see noticeable improvements over both predecessors. Technical performance-wise, the Pro is highly competitive with other $200+ IEMs, offering better resolution, imaging, transience, attack, and separation than the Da Vinci, along with a more natural sound.

Positioned under $400, the Tea Pro fits as a balanced choice between neutral and exciting tunings. Against the clean, neutral Pilgrim or Dusk, the Pro provides a bassier, heavier, fuller sound with more forward vocals and better note weight. Compared to the exciting Estrella, the Pro is more balanced, thicker, and slams harder, while the Estrella offers more dynamic contrast and crispier treble. Versus the similarly priced Hype 4, the Pro delivers harder slam, deeper bass, and sharper vocals with more bite, though the Hype 4 is slightly quicker, smoother, and more balanced. Essentially, the Tea Pro excels as a versatile, resolving set with satisfying bass and well-tuned vocals, making it the best pick for most listeners despite losing some quirks of earlier models.

The Xenns Tea Pro impresses most with its exceptional build quality and aesthetics. The metallic shell feels substantial and premium in the ear, featuring a comfortable wing design and a nice metal nozzle. While slightly larger than its predecessors like the Tea and Tea2, the Pro's shell represents an upgrade in feel and technology, boasting a prettier faceplate. The included cable is thick, braided, and features a swappable termination (4.4mm or 3.5mm), contributing to an overall solid package that feels like a significant step up from previous models.

Sonically, the Tea Pro offers a bassy but clean signature with strong, impactful low end. However, it presents some key drawbacks: the bass can feel slightly boomy or distorted rather than pristine, and the overall presentation leans dark and rich. This comes at the expense of upper treble sparkle, air, and micro-details, resulting in a narrow soundstage and less impressive instrument separation than expected at its price point. While extremely pleasant and engaging for music listening, it feels slightly muffled and lacks the clarity and detail retrieval of many competitors.

When stacked against rivals like the Dunu Da Vinci, Kiwi Ears Quintet, EM10, DUNU DaVinci, Hype 4, or CCA CA4, the Tea Pro often falls short sonically. Competitors generally offer better air, treble extension, cleaner bass, or superior detail. Its own predecessor, the Tea2, is considered more neutral and relaxed. Consequently, while the Tea Pro is a contender with its fantastic build and fun tuning, it might be skippable for those prioritizing pure sound quality. It earns a recommendation for newcomers or those valuing premium construction, but audiophiles seeking the best sound may find better options elsewhere.

Xenns Tea Pro lands as an easy pick around $300 thanks to a natural, versatile tuning that blends tasteful fun with everyday usability. A gentle bass boost adds heft, slam, and definition without muddying the mids, while a touch of upper-mid lift keeps vocals clear—even on bass-heavy tracks—without tipping into thin or clinical territory. Treble stays smooth regardless of shallow or deep fit, supporting lifelike timbre and realistic decay that favors long, fatigue-free listening. Detail comes across as “natural detail” rather than etched; micro-nuances don’t jump out, but nothing feels missing or dulled either.

Against the Top Pro, bass through mids on the Top Pro can sound a bit tighter and more transparent, but its treble risks feeling overcooked and a touch “BA-like,” trading naturalness for extra sparkle and perceived detail. Tea Pro keeps the highs non-fatiguing and tonally convincing, making it the safer everyday choice. The “dream combo” would marry Top Pro’s bass-to-upper-mids with Tea Pro’s treble, but as it stands, Tea Pro remains a well-balanced, easy recommendation for its class—natural yet fun, clean vocals, and a bonus metal shell that seals the deal for all-day use.

Priced between $1,150 and $1,300 depending on custom faceplate options like the butterfly design shown, the Thieaudio Monarch MK IV boasts exceptional build quality with a large but well-contoured titanium shell offering a secure and comfortable fit. Key features include the innovative rumble switch for adjustable bass levels on the fly, a durable two-pin connector, and a solid feel that inspires confidence in longevity. While the included accessories are considered fair but unexciting, the shell's customization potential and rugged construction are major highlights.

Sonically, the Monarch MK IV delivers a detailed, exciting, and clean sound signature that stands as the best in the Monarch lineage. The rumble switch provides two distinct profiles: the red switch (no rumble) offers a balanced, tactful bass presentation, while the gold switch (rumble) adds a satisfying sub-bass shelf ideal for genres like hip-hop. Treble performance is notably improved over the MK III, though a 10k peak requires careful ear tip selection for some listeners. It trades blows with flagships like the $3,000 Annihilator (better sub-bass focus) and the $1,800 Elysian Apostle (more vocal forward), often matching or exceeding their technicalities while offering its unique tuning flexibility.

Scoring a top-tier 9.8, the Monarch MK IV earns its place through a compelling combination of premium build, the highly functional rumble switch, and outstanding sound quality that feels both special and refined. While acknowledging the high price, it represents significant value against competitors like the $2,000 Thieaudio Valhalla or the fiddly Grand Maestro, offering a feature-rich, durable, and sonically excellent package that justifies its position as a current summit-fi favorite.

The ThieAudio Monarch MK4 is a premium IEM that earns a spot in the S-tier for competitive gaming, offering a significant upgrade over its predecessor and A-tier competitors. It features a unique rumble mode switch that adds a satisfying low-end punch and weight without muddying the detailed, reference-grade tuning of the standard mode. While the CNC aluminum build feels exceptional, the design is a bit bulky and heavy, which can lead to some comfort issues during very long, multi-hour sessions.

For gaming, the technical performance is nothing short of phenomenal. The imaging is holographic and the depth perception is absolutely exceptional, providing a critical advantage in tactical shooters like VALORANT where tracking footsteps through walls becomes incredibly precise. The wide and deep soundstage pushes sounds off the player, creating an immersive experience. While rumble mode is preferred for titles like Call of Duty, the standard mode's clean and detailed signature shines in battle royales like Apex Legends, though the 2-4k range can make gunfire a bit shouty at higher volumes.

This is also an absolutely amazing set for music, delivering an elevated level of technicality and resolution. The standard mode offers a fast, clean, and neutral listen with great detail retrieval, while the rumble mode provides a weightier, more engaging bass profile for tracks that benefit from the extra warmth and punch. Ultimately, it's a very high-end IEM that delivers a top-tier experience for both competitive gaming and critical music listening.

The Thieaudio Monarch MK IV presents two distinct tuning options, elevating its versatility. The balanced switch delivers a clean, smooth, and slightly airy presentation, offering a refined all-rounder sound that's very detailed, well-layered, and resolving – essentially a direct upgrade to predecessors like the Monarch MK3 and Top Pro, with slightly more treble detail and air. Conversely, the bass switch provides a significantly fuller, warmer low end with punchy, well-textured bass and a tamer upper midrange, addressing criticisms of thinness in earlier models and offering a specialized, engaging listen for bass-heavy genres.

Technically, the MK IV sits comfortably in the $1,000 tier, offering a slight bump in detail retrieval, refinement, and smoothness over the MK3 and MK2, comparable to the Dunu Glacier and Prestige LTD. While not a giant leap, the dual tuning options make it arguably a better all-rounder than single-tuning competitors; the balance switch excels with acoustic, classical, and cleaner genres, while the bass switch shines with rock, metal, R&B, and pop. Build quality is improved with an all-metal shell, though the flimsy cardboard case is a notable disappointment. Vocals are smooth, balanced, and enjoyable, though sets like the Monarch MK2, Mystic 8, RSV, or Arcanis offer more forwardness or unique character. Bass quality is excellent for most, though pure bass enthusiasts might prefer models like the Thieaudio Origin for its unique texture.

Ultimately, the Monarch MK IV is a highly compelling endgame option for the vast majority. It combines strong technical performance with exceptional versatility through its two excellent tunings, covering a wide genre spectrum effectively. While value-focused options like the Top Pro, Volare, or Mega5EST offer similar technicalities at lower prices, the MK IV's refinement, tuning flexibility, and slightly superior performance make it easy to recommend. It allows listeners to leave the hobby satisfied, provided they resonate with its sound – though chasing marginally better flagships involves steep diminishing returns. The king might be debatable, but the MK IV is undoubtedly a very solid $1,000 contender.

Monarch MK IV lands as a top-three set, sitting just behind the PMG APXSE and CP622B, and it earns that spot with an evolutionary design: a single, tactile rumble switch that can be flipped while the IEM is in-ear—no fiddly pins, no tools. In stock (red) mode it’s a vocal-friendly tuning with restrained mid-bass; engage the switch and the low end lifts, adding note weight without smearing the mids. The shell is metal, build is tight, and all the BAs are Sonion, signaling premium parts and execution.

Low-end performance nails both 808 drops and classic rock kick drums (“When the Levee Breaks”) with satisfying slam—better with the switch on—while bass guitar texture (pulls, plucks, string ring) stays articulate into the lower treble. Vocals are clean in stock mode and gain a pleasing husk and density with rumble engaged, making artists like Neil Young and Mark Knopfler pop. Upper mids/treble avoid glare and long-term fatigue, turning this into a true “sofa set” for hours-long sessions.

At $1,400 it competes shockingly well against far pricier summit-fi gear—no veil, no masking, just balanced resolution and a flip-to-taste bass shelf. Compared to Valhalla, the MK IV’s instant two-flavor flexibility pushes it ahead on value; bone-conduction curios like Origin feel more niche by contrast. Net: the best ThieAudio to date, an easy recommendation, and likely the new #3 overall—thanks to that simple, game-changing rumble switch that future proofs the tuning.

The ThieAudio Monarch MK4 presents a well-extended, refined treble that measures cleanly and feels more polished than earlier iterations, though the overall tonality can read a touch thin. Against its sibling Valaha, the MK4 trades warmth for a clearer top end, keeping the presentation crisp without obvious harshness.

Between the pair, the MK4 takes the edge on technical performance—notably resolution—thanks to a bit more upper-treble energy and a more controlled bass shelf, while the Valaha offers extra mid-bass thump and a slightly warmer tilt. Net result: the Monarch MK4 remains a standout around $1,000, balancing precision and extension better than its stablemate.

Precogvision original ranking

ThieAudio Monarch MK4 comes in at $1,150 with a tribrid array—2 DD + 6 BA + 2 EST—a chunky stock cable with friction-fit swappable terminations, and a genuinely excellent, in-ear-operable “Rumble” bass switch. The new metal shells look tidy, but the fit is very large; on average ears it tends to sit a bit out of the concha and feel unstable (seal is doable, comfort is mediocre). Build details like the firm chin slider are nice, yet the cable bulk and loose termination retention detract from daily use.

Tonally, stock MK4 aims for a clean-neutral presentation with a meaty, sub-bass-focused lift, lively upper registers, and excellent extension. The flip side is a slightly dry / clinical character with a hint of treble hardness that can leave notes feeling a bit bodyless. Engaging Rumble mode thickens the curve from ~300 Hz down—more warmth and weight, bordering on “gigabass” territory—making the set fuller and more fun, though arguably too bassy for purists. Staging and imaging are solid, and resolution is high, but macro-dynamics land behind peers; compared side-by-side, sets like Dunu Glacier and 64 Audio U4S feel punchier, while Valhalla sounds warmer, smoother, and more effortlessly resolving.

Overall, MK4 is a technically capable tribrid with two distinct tunings on tap—clinical-clean stock and warmed-up Rumble—but it’s held back by fit size, cable quirks, and that slightly wooden bass texture. For listeners chasing a bright-leaning neutral with legit sub-bass reach (and who can accommodate a big shell), it’s a compelling try; in this lineup, though, it settles at a three-star recommendation next to more engaging or comfortable alternatives.
