Youtube Video Summary
Aful Performer 5+2 lands as a hybrid of the beloved Performer 5 and the punchier Explorer. The unboxing is the familiar P5 affair—same case, same style of tips—nothing flashy, but solid. The shell mirrors the P5 in size with a comfy little stabilizing wing that locks in well. No metal nozzle or front filter here, yet tip retention is secure and hassle-free. The flat 2-pin socket is straightforward, and the stock cable feels thick and supple with a reliable chin slider and handy red/blue channel markers. Overall: understated build, great ergonomics, daily-driver ready.
Sonically, this one aims neutral with a very distinct top end—clean, dynamic, incisive. Think switching from black-and-white to color; cymbals and overtones pop with a slightly crunchy/pristine edge that energizes detail without turning harsh on good recordings. Bass isn’t about sheer quantity; it’s about slam and dynamics—quick on the draw, well-controlled, and satisfying when called upon. Vocals sit a notch forward, microdetail is strong, and the overall presentation is coherent, clear, and technical with convincing stage, resolution, and imaging. Not a treble-shy or bass-bombed tuning—more a refined all-rounder for those who want clarity and bite.
Versus the original P5, the 5+2 fixes the missing “air” and soft edges, trading them for crisper transients and better extension. Compared with Explorer (a value champ), the 5+2 brings superior upper-treble reach, detail, and vocal focus. Against Performer 8 and Cantor, it feels more visceral—the P8 is smoother and more relaxed, while Cantor pulls finer microdetail but with less bass slam. Sets like Dino Quattro or J’s Estrella bring bigger fun or treble theatrics, yet the 5+2’s balance and everyday versatility win more often. Net take: a neutral-leaning, highly technical upgrade that stands tall in its bracket—easy to recommend to anyone chasing clarity, speed, and controlled impact over pure warmth or excess bass.

Youtube Video Summary
EPZ K9 brings a flashy spec sheet and premium feel: a 9-driver hybrid (1DD+8BA) dressed in a world-class shell that fits securely, vents properly, and looks gorgeous with its blue-white case. The stock cable offers swappable 3.5↔4.4 termination and a steady chin slider, though the fabric sheathing and barely visible L/R markers are quirks. Originally teased near $300 and now closer to $400, the package screams polish more than compromise.
Sonically, this is a V-shaped tuning with rich bass, thick lower mids, and extra energy in the 3–6 kHz band that can make stick hits and sibilants feel a touch sharp. The midrange clarity is only decent and the upper-air/treble extension is just okay, but staging comes across pleasantly open. Graph comparisons paint the picture: versus EPZ’s own P50 (safer, flatter upper mids) and the more majestic, warm-lean V of the EPZ 530, K9 pushes that presence region a few dB higher. Sets like Afu Dawn X flatten that band while extending air; Softears Volume offers a very similar profile but even more 5–6 kHz energy; and options around this price—Magic Top Pro, Yu9 Chua—show alternate takes with either dipped presence or stronger bass/1 kHz support.
In practice, K9 aims for excitement: weighty bass, a forward upper-mid/low-treble bite, and a lively stage. Listeners craving a crisp, energetic V will find plenty to enjoy, while those sensitive to brightness or seeking mid clarity and airy refinement may prefer the P50, 530, or similarly priced competitors. Stunning build and respectable performance, but the tuning choices make it a taste-dependent recommendation rather than a universal pick.

Youtube Video Summary
Performer 7 lands with a neutral-balanced, laid-back tuning and good treble reach. The presentation is clean and generally safe, though there’s a touch of sizzly “planar-ish” timbre up top. Technicals are solid for ~$200—slightly behind sets like Quintet and Super Mix 4, about on par with Nova. Bass from the dual 6 mm DDs is tight, controlled, and free of bleed, but lacks the slam and rumble of competitors using larger drivers; mids are well separated with decent layering.
The weak spot is vocal extension: a push around 1.5 kHz tries to bring them forward, but a dip through 3–6 kHz keeps them from opening up. Tamer upper-mids help avoid fatigue for rock/metal, yet the modest low-end impact leaves drums and basslines feeling uneventful. It’s a mid-volume set that doesn’t scale well—turning it up accentuates the 1.5 kHz emphasis and treble sizzle. Treble isn’t peaky, just a bit glassy at times; for K-pop the smoother mids can work if less extended vocals are acceptable.
As a value play, there are stronger options: Nova, Chopan, and Super Mix 4 offer better bang-for-buck; for a similar clean/neutral target, Tanchjim Origin sounds more natural with better bass texture and vocal reach, and DynaQuattro adds sub-bass and fuller vocals—none with the planar-ish timbre. Even AFUL’s own P5 is cheaper and more fun, while the Explorer undercuts the price and scales impressively. In today’s crowded market, P7 is a competent all-rounder but not distinctive enough to stand out.

Youtube Video Summary
EPZ K9 lands as a sweet, balanced all-rounder with a tasteful, slightly V-shaped tilt. Bass is snappy and well-controlled, with a mid-bass fill that adds natural note weight to vocals and drums without muddying the mids. Treble extends cleanly with a hint of air, steering clear of both dullness and sharpness, while imaging is a touch sharper than entry peers. Think EM6L’s vibe but less shouty up top, a bit more resolving, and a clear upgrade path from sets like the Clean/EW300.
Against rivals, K9 takes a more vocal-centric approach: fuller mid-bass, smoother presence, and better slam/body on drums. Astral counters with stronger sub-bass texture, extra air, and a tamer upper-mid for high-energy genres; both trade blows on detail with K9 edging imaging. Versus Odyssey, K9 offers cleaner treble extension and forward vocals, while Odyssey is bassier, with deeper sub-bass texture and louder-volume scaling. Overall technicals sit around Pilgrim/Dusk level, which is solid for the price, especially with the nicer cable, case, and a black color option.
Usability is largely easygoing—tip-rolling is flexible and the stock clears keep things smooth—though the shell edge can feel uncomfortable over long sessions. Best at mid-volume listening (around 60–65 dB); push higher and upper mids/treble can get lively on K-pop/EDM, while R&B/indie scales sweetly up to ~75 dB. Compared with bass-tilted sets (Tea Pro/Hype 4/Estrella/Punch/Martello), K9 is cleaner, tighter, and more mid-range focused; versus neutral leaners (Pilgrim/Dusk/Canon Pro/“5+2”), it has a more complete upper-mid for vocals. Not a market-breaker in pure price/perf, but as a refined, musical package with balanced tonality and comfort-adjacent caveats, K9 is a very solid all-rounder.

The AFUL Performer 5+2 (also listed as “Performer 7”) uses a 2DD+4BA+1 micro planar driver array and AFUL’s LC-network crossover plus a 3D-printed acoustic tube system, aiming for clean band splits without smearing. The shell also integrates a high-damping air-pressure balance system, a design AFUL has used across its line. Official listings put MSRP around $229 and outline the same core tech features.
Tonally it trends neutral with a sub-bass lift: bass has solid depth and texture, mids stay relatively linear, and the presence/treble region adds energy without veering into sharpness on most chains. Multiple reviews characterize it as warm-neutral with bass boost or slightly V-shaped depending on perspective, which matches listening notes about a lively but controlled upper end. Sensitivity and load are portable-friendly (≈109 dB, 15 Ω), so it reaches performance without demanding amplification.
Technicalities are competitive for the class: imaging is tidy with good instrument separation, micro-detail retrieval is above average, and soundstage is moderate (more width than depth). Build and comfort are typical resin-shell fare; some users note occasional lower-treble bite depending on tips and recordings, so treble-sensitive listeners may wish to pair accordingly. Overall value is strong at its price, especially if a clean, bass-supported neutral curve is the priority.

The EPZ K9 is a 9-driver hybrid (1DD+8BA) with a 3-way acoustic/electronic crossover, rated at 14 Ω and 108 dB sensitivity; it also ships with interchangeable 3.5 mm/4.4 mm plugs, making it easy to pair with portable sources. Retail pricing varies by region—seen around $299 at some retailers and into the low-$400s elsewhere—so value will depend on where it’s purchased.
Tonally, K9 presents a warm W-shaped balance with substantive mid-bass and a restrained but present upper-mid/treble rise, aiming for smoothness over bite. Frequency-response sets published by community sources also show insertion-depth sensitivity (deep vs shallow), which helps explain reports of “calmer” treble and broader perceived width with deeper seals.
Technical performance is competent for the segment: macro-dynamics and bass slam are a noted strength, while resolution and imaging sit a touch below the class leaders; stage is more wide than deep, but cohesive for a multi-BA hybrid. Multiple long-form impressions describe it as clean and open yet non-fatiguing, which aligns with a safe-tilt treble and fuller lower mids.

Youtube Video Summary
Naming drama aside (P5+2? just call it Performer 7), this Aful packs a quirky driver party: 2DD for low end, 4 BA split across mids/treble, plus a tiny micro-planar for the highest sparkle, all marshaled by Aful’s neat miniature crossover. The shells are lightweight, comfy and prettier than they need to be; the cable feels “don’t bother swapping” nice, with 3.5 or 4.4 options. The box is loaded with silicone tips but no foam—a miss, because the right seal changes everything. Price target sits around $250, which sets expectations high but not ridiculous.
Stock silicone yields a surgical, respectful tuning with bass that skews neutral and controlled. Swap to well-sealing foam or hybrids and feed a juicy source (warm Class A or tubes) and the set wakes up—stage snaps into a cohesive scene right in front, imaging gets laser-etched, and that micro-planar adds a pinch-of-salt treble spice without turning harsh. It’s an up-close presentation—sometimes almost claustrophobically detailed—in the best way: think “men with trumpets in the head,” precise placement, and excellent extension up top. Not as rowdy as the Explorers; more like a surgeon in a Hawaiian shirt—technical, but with a wink.
Practical upside: the clarity and positioning make this great for gaming and even viable for mixing/mastering checks; just don’t crank it into pain territory. Bass stays tight and responsive, treble sails high, and coherence holds. Tip and source matter a lot: with foam + warm power, it sings; with plain silicone, it’s merely polite. Final tally: a confident 8.5/10—doing a lot right at its price, dinged half a point for making everyone do math on the name.

Youtube Video Summary
The AFUL Performer 5+2 (Performer 7 / P7) takes the P5 recipe and adds a second 6 mm dynamic for the lows and a micro-planar for the highs, nudging MSRP to $240. Unboxing mirrors the P5: nine pairs of tips and a decent case, but the accessories feel bare-bones at this price—no foam tips and a non-modular cable, even though the included 8-wire is supple and well-behaved. Build is classic AFUL: 3D-printed resin, blended nozzle (no mesh or lip—watch tip retention), single rear vent, and striking blue-green mosaic shells inspired by Suzhou gardens—cool-wall approved with four compliments to one “meh.” Fit is semi-custom and a touch chunkier than P5; comfortable for most, a conditional pass for small ears. Note a sporadic batch quirk: some units have over-tight 2-pin sockets; exchanges fixed it for affected buyers.
Tuning sits in warm-leaning neutral territory. The dual dynamics deliver punchy, textured bass that rumbles without bloating; guitars and drums carry convincing weight. Mids are the star—rich, full-bodied, vocal-forward without shout, with clean separation and natural tone. Treble from the micro-planar is smooth yet energetic: cymbals and vocal harmonics sparkle, special effects have bite and body, and only treble-sensitives may find hot mixes a bit lively. Technicalities impress for the money—detail retrieval and nuance feel a class up—while stage and imaging are solid rather than showy.
Against peers: the Tangzu x HBB budget pick mirrors the overall tonality but P7 offers higher resolution and more treble finesse; the planar “Heyday” alternative is brighter/faster with leaner bass; versus Performer 5, P7 brings tighter low-end, smoother treble, and better extremes detail; the Fresh-collab competitor pushes vocals further forward with bigger stage but leaner lower mids. Verdict: a versatile all-rounder that suits broad libraries and even content creation thanks to its balanced tonality and detail. Not for bassheads, trebleheads, or strict Harman-lean seekers, and the accessory pack/cable quirk holds it back from a slam-dunk. For roughly $240, though, it’s a brilliant, resolving upgrade in the AFUL line.

Youtube Video Summary
Aful’s Performer 5+2 upgrades the original hybrid with 2DD + 4BA + 1 micro-planar tweeter and lands around $240–$250. The unboxing is practical: three sets of silicone tips, a pocketable puck case, and a soft, nicely draping cable (available in 4.4 or 3.5), though the braid can look a bit loose and the pre-formed hooks run large. The resin shells shift between blue and green under different light; fit is medium-large, very stable, and comfortable once the right tips are found. Note the narrow nozzle without a retaining lip and partially exposed bores/filters—tip grip is key and a little care prevents ear-gunk ingress.
Tonally this leans mild V-shaped: a clean midrange with a confident bass boost, a touch of lower-treble presence for bite, and well-extended air up top. The result is more incisive and punchy than the original P5, with clearer on/off transients that aid separation and layering. Trade-offs show as a hint of gritty/plasticky treble texture on cymbals and brushes—not harsh, but less natural than ideal—while the bass stays tight and exciting.
Against Aful’s Explorer, this sounds brighter, more spacious, and more technical; Explorer plays warmer/denser with smoother treble but less openness. Versus the pricier Thieaudio Oracle MK3, tuning is broadly similar: Oracle is smoother and deeper with a softer attack, while the Performer 5+2 brings more snap and engagement for less money. As a modern mid-tier hybrid, it absolutely still has a place—energetic, spacious, and well-executed—earning a solid four stars.

Youtube Video Summary
The AFUL Performer 5+2 takes the familiar hybrid recipe of dual 6 mm dynamics, four balanced armatures and a micro planar and spins it into a distinctly vocal focused presentation. Vocals are pushed very close, giving an intimate, close talker character that will immediately stand out from more typical U shaped hybrids. This forwardness comes at a cost, as the overall soundstage feels flatter and smaller than many competitors, with the midrange taking center stage at the expense of a more spacious image.
The dual 6 mm drivers deliver a sub bass tilted low end that has respectable rumble and enough level to support genres that appreciate extra weight, while avoiding obvious boom or bloat. Impact and tactility are on the softer side, and combined with the elevated midrange and treble, bass presence tends to sit very close to the vocals rather than carving out its own layer. This crowding effect, together with the warm, smoothed textures, means layering and separation never really open up, giving the Performer 5+2 a more compact, blended presentation than many modern tribrids.
The treble region is where the tuning feels least controlled, with peaks across the upper mids, presence and air bands that can bring out snare hits and sibilants and push the micro planar into an overdriven, slightly unnatural timbre. The intended advantage of the micro planar is largely lost in this boost, keeping overall technicalities such as detail retrieval, imaging precision and stage depth firmly in the moderate camp rather than a clear step up from AFULs other models. As a result, Performer 5+2 emerges as a niche choice for listeners who strongly prioritize upfront vocals and do not mind a smaller, more intense stage, while those looking for a more balanced, spacious and natural presentation will likely find better options elsewhere.

Sub-bass reaches good depth—elastic and bouncy rather than thunderous—giving just enough physicality without overloading the mix. The bass isn’t heavy-handed; quantity is moderate, punch on the softer side, yet always clearly outlined with clean texture and tight control.
Mids tilt slightly toward female vocals, made airier by a 500Hz dip that trims warmth and opens the space. Vocals sit forward, sweet, and expressive, aided by a mild lift between 600Hz and 1 kHz. A 6kHz rise sharpens edges and adds clarity to cymbals and hi-hats, but a smooth roll-off past 5–8kHz keeps sibilance comfortably restrained.
Treble is bright but polished, extending easily with a gentle 13kHz rise that introduces a touch of air without excess sparkle. The stage impresses with width and layering, offering a lively yet well-controlled image.
Verdict: EPZ K9 isn’t about brute force—it’s about coherence. Smooth highs, open mids, articulate bass, and a wide stage make it an elegant, finely balanced hybrid that performs far beyond expectation.
