Clean balanced tuning done right. A better tuned MEGA5EST & MOONDROP Meteor with fuller low-end, and more treble extension, same tech, but more dynamic - also half the price. A Mega5EST with better vocals and dynamics but less smooth and airy. Low-end will be weak to some people and on certain tracks. Not the most unique sound since it's clean/neutral/balanced.
Youtube Video Summary

The EPZ P50 comes in hot as a new tribrid and a potential $200 neutral benchmark, trading sterile restraint for a more vocal-centric presentation. Versus the MEGA5EST, vocals sit a touch more forward—adding emotional weight and clarity—while the MEGA5EST still edges it on sheer smoothness and EST “air.” Compared to Meteor, the P50 fills in the lower mids, dials back 1–3 kHz glare, and opens the top end a bit; Meteor stays a hair softer up top. The catch is bass: the P50’s DD is competent but not a sub-bass shaker—expect clean rather than authoritative slam.

Against peers, the P50 sounds fuller and more natural than Supermix 4 (which is brighter and more “hi-fi” energetic), and it trades blows with Odyssey: Odyssey brings better bass texture and treble micro-detail, while the P50 delivers superior vocal clarity and a touch more air. It excels at mid-volume listening—Volume S needs more gain to bloom—and outclasses lighter, air-tilted sets like “K4” style tunings when male vocals or body are the priority. Accessory game is strong too: a nicer cable and a genuinely sturdy hard-leather case sweeten the deal. Not the most “unique” flavor and not for bassheads, but as a balanced, clean, vocal-forward option around $200, P50 is an easy recommendation for those chasing neutrality without the vanilla.

A bassy all-rounder, and cleaner Doscinco for $100 less. Very versatile with the different nozzles - goes from bassy to clean all-rounder. Solid packaging and accesories. Competitive tech, but not as value like Supermix4/EM6L/EA500LM.

Affordable tribrid with a vocal-centric, general-appeal tuning and standout imaging for the price. Execution suggests where sub-$100 hybrids are heading in 2025. Cohesive mid-centric tuning with extended treble from micro-planars, spacious stage, sharp imaging, and excellent value under $100. Sub-bass is conservative and the clean, revealing treble can be unforgiving on hot tracks; the shell is on the larger side and the nozzle lacks a lip.
Youtube Video Summary

The EPZ P50 is a five-driver open-back hybrid (1DD + 2BA + 2 micro-planars) that arrives with a solid accessory kit and a sensible price. The tuning is the highlight: a vocal-centric balance that avoids the over-energetic tilt of some Harman-leaning sets, while keeping a clean background and strong clarity. Sub-bass is trimmed for control, mid-bass adds body, and the result is natural male vocals and a presentation that feels both transparent and organized.

Upper mids rise earlier for familiar presence, and treble is extended by the micro-planars yet kept in check for wider appeal than brighter peers. Resolution is high for the class and the set can be revealing, sometimes asking for a touch more volume and occasionally sounding a bit unforgiving on hot masters. Bass is snappy rather than booming, trading rumble for speed and definition to keep the midrange clean.

Stage and imaging are standouts: spacious, precise, and helped by bass control and the open shell design. Compared with typical u-shaped ~$200 hybrids, this tuning prioritizes mids and coherence, showcasing a clear, extended top without brittleness. As a sub-$100 tribrid, the P50 delivers impressive value and feels like a sign of what is to come in this segment.

Bass-tilted, fatigue-free hybrid with excellent build and accessories; closer to Delci than Clean and priced appropriately around $130. Not a detail monster but coherent and easy to enjoy. Excellent metal build and accessories with coherent, bass-friendly tuning that avoids fatigue. Strong sub-bass masks lower mids and the safe upper treble reduces air, detail and overall technical performance.
Youtube Video Summary

KEFINE Quatio delivers the brand hallmark: a rock-solid metal build, generous accessories and a value-first hybrid at roughly $130. The tuning is a modified Harman with elevated sub-bass and modest mid-bass, giving a warm, satisfying low end while keeping upper-mid energy trimmed for non-fatiguing listening. Coherence is strong because the dual dynamic drivers carry the spectrum up to about 5 kHz before the BAs join.

That bass tilt also pulls the mids inward; body and lower-mid resonance are a bit light, so vocals and instruments can sound less filled out. Treble has clear lower-treble presence but a safe upper treble, trading air and sparkle for smoothness, which limits perceived resolve, micro-detail and layering compared with more technical hybrids. It sits closer to Delci than Clean: musical, easygoing and preference-friendly rather than a detail or resolution showcase.

Quatio feels priced exactly where it should be: a bass-friendly, coherent daily driver that favors timbre and comfort over chasing technical fireworks. Listeners who dislike lean U-shapes or bright Harman takes will likely prefer this voicing; those seeking airy extension and class-leading detail should look elsewhere.

The EPZ P50 is a tribrid with a 10 mm dynamic driver, two balanced armatures, and two micro planar drivers, implemented in a semi-open back shell and a three-way crossover—an uncommon configuration at this price tier. Listings and spec sheets place impedance at 20 Ω and sensitivity around 106 dB, with interchangeable 3.5/4.4 mm plugs and 0.78 mm 2-pin connectors, positioning it as a flexible daily-carry IEM near the $200 mark.

Subjectively, multiple reviews converge on a neutral-with-bass-boost presentation: sub-bass is tight and weighty when called for, mids stay clear and slightly forward, and treble is extended with extra energy from the planar tweeters. This yields a clean center image and articulate vocals without obvious mid-bass bloom, though the upper-treble emphasis can read “sharper” on some recordings.

Technical performance is competitive for the class: reviewers note solid imaging, above-average separation, and a stage that feels wider than typical sealed IEMs—qualities plausibly aided by the semi-open design and multi-way damping. Trade-offs include reduced isolation versus closed shells and a treble tilt that may fatigue treble-sensitive listeners at high volumes, but overall resolution and micro-detail retrieval punch above its price.

The KEFINE Quatio impresses with its premium build quality and versatile tuning options. Its lightweight aluminum alloy shells offer both durability and comfort, while the included modular cable with 3.5mm/4.4mm terminations provides flexibility for various sources . The standout feature is the three interchangeable nozzles: gold for a bright, detailed signature, silver for balanced neutrality, and black for a warm, smooth presentation - allowing users to tailor the sound to their preferences .

Sonically, the hybrid 2DD+2BA configuration delivers punchy bass and textured mids across all tunings, with the gold nozzles particularly enhancing vocal clarity and treble energy . While bass enthusiasts might desire more impact, the overall coherence and natural timbre are exceptional for the price point. The technical performance shines through articulate imaging and a spacious soundstage, though some critical listeners may note slight treble roll-off on the black/silver nozzles .

At $129, the Quatio offers remarkable value with its triple-tuning system and comprehensive accessory package including multiple ear tips and a premium case . It stands as a compelling choice for those seeking adaptable sound signatures without compromising on build or technical prowess.

Wonderful vocal forward all-rounder. Balanced, clean, detailed, sound. Has Length mode issues. So the Treble might be harsh for some. Nice accessories. Custom designed versions available.
Youtube Video Summary

EPZ P50 comes as a tribrid at $185 with a surprisingly complete kit: a sturdy leatherette case, modular 3.5/4.4mm terminations, three silicone tip sets, and a cleaning cloth. The resin shells are semi-custom with aluminum faceplates; comfort is generally good but anatomy-dependent, and the stock cable—while well finished—runs on the stiff side. A standout twist is the factory customization option (~$225 total for the “Grindphones” style), which notably doesn’t alter the tuning in any meaningful way. The set is easy to drive, shows minimal change with impedance adapters (a touch warmer/more vocal-forward), and avoids pressure issues thanks to smart internal venting.

Sonically, tuning sits as a controlled, mild V: bass is just north of neutral with pleasing texture and impact, mids stay clean with an engaging female-vocal emphasis, and treble adds airy sparkle without turning tizzy—though insertion depth can trigger length-mode variability for some ears. Technical chops impress at the price: detail retrieval punches up, imaging is precise with good separation, and stage reads average but coherent. Against peers, P50 feels more resolving than Kiwi Ears K4 (trades bigger bass/sparkle for better mid clarity), brighter and more vocal-present than the neutral-leaning Ziigaat Lush, and echoes a Dunu Da Vinci vibe with less bass. Verdict: tremendous value and a terrific pick for vocal-centric libraries—highly recommended to audition first if treble sensitivity or fit quirks are a concern.

Bass can be a little bit on the distracting side if you are looking for a neutral sound signature. Contrasty meta-tuning.
Youtube Video Summary

EPZ’s P50 feels like a breakout for the brand: a compact, medium-small shell with a vented faceplate that’s marketed as “open-back,” yet isolates like a typical IEM. The unboxing is tidy at this price—carry puck, a real microfiber cloth, and two sets of generic tips—while the modular cable (screw-lock swappable termination) is handy if a bit thin, stiff, and kink-prone; the 2-pin plug sits slightly proud of the socket and the “R” marking is visible on the outside. The long nozzle (~5.5 mm diameter) can push fit depth, so shorter tips (e.g., NF Audio-style) help; once set, stability and comfort are excellent. Overall build looks clean and modern, if a touch editorial compared with EPZ’s other shells.

Sonically, P50 embraces the current tilted diffuse-field “new meta” with a mostly neutral, natural presentation and a later-rising, sub-bass-centric lift that gives bounce rather than mid-bass thump. There’s a hint of extra presence around the 4–5 kHz region that adds macro-contrast—vocals pop with definition and separation is crisp—while upper treble stays safe: cymbals are clean but a bit light in weight. Bass is tight and incisive rather than slammy; micro-texture on vocals is good, though the set favors that big, “stagey” contrast over ultra-fine grain. It’s easily EPZ’s best tuning so far: clear, organized, and engaging without drifting from neutral-ish aims.

Against peers, Kiwi Ears K4 tracks a similar target but sounds lower-contrast and can blur on dense mixes; P50 hits harder on transients, images more cleanly, and keeps busy tracks sorted, while K4 offers a richer midrange with “frothier” treble. Versus the Binary Chopin, Chopin is warmer, fuller, and more mid-bass driven—more “analog” and atmospheric—with deeper perceived space but a bulkier fit; P50 is leaner, clearer, and the least bass-forward of the three. Verdict: a confident 4/5 for delivering a small, comfy fit and a clean, contrasty neutral that competes squarely around $200–$250. If the brief is “neutral with a bit of drama,” this is a strong pick—and a promising sign of where EPZ can go next.

Youtube Video Summary

The EPZ P50 arrives as a ~$200 tribrid with a slick presentation: FR graph on the box, a puck-style case, plenty of tips (oddly two identical sets), and a nice microfiber cloth. Build leans premium with a semi-open back and a faceplate that gives “arc reactor” vibes. The custom shell offers a secure fit for most, though very small ears—or anyone sensitive to an inner wing—may need caution. The modular cable (3.5/4.4 mm) is practical yet slightly stiff and retains some memory; isolation is typical of sealed IEMs despite the semi-open styling.

Sonically, the P50 goes for a warm-balanced tuning. Bass quality impresses: bouncy with deep sub-bass reach, prioritizing texture and control over sheer quantity (more thump is possible via an impedance adapter). Mids read natural with a touch of warmth—male vocals shine—while female vocals can feel a bit lean due to a more relaxed upper-mid energy. Treble is smooth, inoffensive, and “planar-clean” without planar timbre, with only a slight wish for more top-end extension.

Technical performance is the star. The micro planars pull out micro-detail unusually well for the price; imaging, separation, and overall resolution feel confidently executed, making guitars pop and busy mixes easy to parse. That clarity translates to gaming, where positional cues and crowded soundscapes (think battle royale chaos) remain intelligible—worthy of a two-controller gaming nod. Overall, the EPZ P50 is a solid contender at this price: balanced tuning with standout detail retrieval and imaging, tempered only by mids that play it a little safe. For listeners unbothered by a gentler upper-mid lift, it’s well worth the money—a two-star recommendation.
