Youtube Video Summary

Punch Audio Martilo steps in as a new-brand debut with a confident package: a hybrid array (planar + BAs + DDs), a metal nozzle, proper venting, and a recessed 2-pin socket set into a shell that sits securely thanks to an anti-tragus catch. The faceplate gives off AFUL Performer 7 vibes, the included cable is supple with clear R/L markings, and the textured carry case plus two tip sets round out a thoughtful accessory kit. Priced around $329—with occasional deep discounts during big Linsoul sales—build and accessories feel dialed in for the bracket.

Sonically, this is a bassy set that still behaves like an all-rounder. The bass shelf rises from roughly ~150 Hz, bringing weight and warmth without turning podcasts and vocals into mud; upper-mids are present yet controlled, minimizing shout, while mid-treble energy keeps things crisp. Female vocals avoid huskiness, note weight is satisfying, and the tuning strikes a balanced, fun profile that works across genres. On the graph it hugs a safe line, then sprinkles in extra low-end for flavor—bass-head friendly, but not a blunt instrument.

In A/Bs, it addresses the AFUL Explorer’s softness with more bass and mid presence, and compared to similarly priced Kiwi Ears Astral (the safer neutral pick), Martilo offers the spicier, more engaging option. Against “specialist” bass sets like Deuce or Quantum, Martilo feels cleaner in the mids, less abrupt in its slam, and more universally usable; versus warmer bass champs (e.g., Mega 5 Bass), it trades some warmth for clarity and refinement. This isn’t sterile “audiophile-neutral”—it’s audiophile-fun done with taste. Scoring reads like: bass (10/10), note weight (10/10), mids (9/10), with surprisingly solid highs, stage, and imaging for the money. Not flawless, but distinctive, well-tuned, and easy to recommend—especially for listeners who want real bass without sacrificing everyday versatility.

A little bit too much lower trebble, but it's still a good balanced set.
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.

Cheaper, and slightly more energetic HBB Punch with slightly less mid-bass and slam. Endgame "balanced" basshead. Imaging feels sharper than Punch, but treble is not as smooth, aside from that very similar tech and low-end.

All-rounder with slight v-shape tonality. EW300 upgrade. Natural and sweet vocals, nice mid-bass slam, treble is nicely extended, well-balanced with a mix of smoothness and contrast, and great packaging and design.
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 Punch Audio Martilo delivers a powerful bass experience that dominates its signature, featuring a substantial 14dB sub-bass boost. This emphasis creates visceral, physical rumble, especially in electronic or hip-hop tracks, yet avoids overwhelming the lower mids due to a precise 200Hz crossover. While the dual dynamic drivers generate impressive slam and texture, a slight bloom can occasionally creep into the low-mids on very busy tracks, though it generally maintains better control than many bass-focused rivals.

Surprisingly, the midrange retains clarity and naturalness despite the bass foundation, handled competently by the Knowles balanced armatures. Vocals, both male and female, sound full-bodied and avoid the huskiness or recession common in bass-heavy tunings, while instruments like guitars retain decent texture. The planar magnetic driver contributes a smooth, non-fatiguing treble with adequate air and detail retrieval, though it doesn't quite reach the sparkle or ultimate extension of dedicated electrostatic tweeters.

Technical performance is solid for its price and tuning goal, offering a wide soundstage with good depth and effective layering, particularly impressive given the bass quantity. Imaging is precise enough for accurate placement of instruments. While the bass is the star, the overall presentation manages to avoid being a one-note experience, offering a fun yet reasonably balanced listen that works across more genres than typical basshead sets.

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

Punch Audio Martilo hits the brief for bass-centric listeners. The tuning kicks up from ~200 Hz, driving a potent low end, then rides a flat porch through the mids with a gentle ear-gain that crests around 3 kHz before easing off. It mirrors the well-known Kiwi Ears collab curve but with a touch more upper-mids energy for cleaner, clearer vocals. At $279 with the card (and still competitive around $320), this set undercuts many rivals and, for libraries heavy on rock and hip-hop, feels purpose-built.

The hybrid stack—2DD + 2 BA (branded) with a planar on top—keeps the upper-mids sensible and lets the treble play from roughly 5 kHz+ without glare. Personal preference might lean to EST or a high-end BA super-tweeter, but here the planar’s implementation stays out of trouble by avoiding an overcooked 1–3/4 kHz shelf. Result: strong slam, stable mids, and treble that’s present yet subordinate to the preceding bands—focused on transparency rather than flash.

Beyond sound, the packaging and cable show real forethought—distinct from the usual cookie-cutter unboxings—and the overall execution reads like a brand finally dedicated to the low-end community. With more models in the pipeline (including a budget single DD and a planar+DD combo), Martilo arrives as a market shaker for bass lovers seeking muscle without muddying the mids. For the asking price, it’s an easy recommendation to audition—especially if the playlist is built on rhythm sections and big grooves.

Great basshead set with strong technical chops. Great value, fun, and engaging without sacrificing clarity. Boosted, clean, and textured bass. Mids are surprisingly clear for a bassy set. Treble’s smooth and non-fatiguing. The bass might be too much for some.
Youtube Video Summary

Boom — time for bass. Punch Audio’s Martilo is a tribrid (2×8 mm DD + 2 BA + 1 micro planar) coming in around $330. The package is stacked: sturdy square case, extra filters, multiple tip sets, and a genuinely excellent modular 3.5/4.4 cable that lays flat, has no microphonics, and a firm chin slider. The shells are ergonomic with venting, metal nozzles with a proper lip, and a small nozzle diameter (5.9/5.0 mm) that helps seal; comfort and passive isolation are both strong.

Sonically, this is unapologetically bass-focused without being bass-only. Expect massive sub-bass depth and a punchy mid-bass, yet the low end stays tight, controlled, textured and doesn’t bleed. Mids retain clarity with non-shouty presence, while treble is crisp, smooth, non-fatiguing with decent extension (not ultra-airy). For a bass-heavy set, technical performance is solid: detail is good, and imaging/separation keep busy tracks coherent and energetic.

Against Hisenior’s Mega5EST Bass Plus, Martilo hits harder, feels more engaging, and offers better vocal clarity — and it steamrolls on value at the lower price. Compared with Xenns Tea Pro, the Tea Pro is a bass-lover all-rounder that spotlights vocals/instruments more; Martilo goes full bass-head with bigger rumble and impact. Ideal for listeners who crave deep slam but still want clarity, comfort, and great accessories; not for neutral/reference chasers. Final verdict: 4/5 — it truly punches above its price.

Youtube Video Summary

The Punch Audio Martilo shows up screaming BASSHEAD on the box, but the tuning is smarter than that. A hybrid stack—2×8 mm DD + 2×BA + 1 planar—delivers bass that hits when the track calls for it, then gets out of the way. The surprise is the huge soundstage: airy, wide, borderline cinematic, so pianos, crowds, and live recordings feel expansive rather than claustrophobic. Low 9 Ω impedance and easy efficiency keep the power demands chill, though a low-impedance cable is recommended.

Tip rolling matters. With thin-wall silicone (e.g., Dunu S&S) the stage opens up and balance feels right; foams and some wide-bore options can push treble into a slightly sharp zone on certain tracks. Tonality reads clean and natural—warm-adjacent without a blanket—so everyday music stays unbloated, while proper sub-bass test tracks pressurize with that “firm hand on the chest,” not a sledgehammer.

Build is solid: thick, comfy modular cable with swappable plugs, flashy red shells, and a comically oversized box for a modest accessory set (silicone + foams). Street price around $330 lands in the sweet spot—easily justifying $375 by ear. Think “poor man’s Mega 5 EST Bass Plus”: similarly satisfying slam and stage, with the pricier set showing a touch more upper-mid/treble refinement. Not just for bassheads—more like a full-range thrill ride that lets music breathe and hit when it should.

EPZ K9 follows a confident W-shaped tuning that strikes a fine balance between energy and smoothness.

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.
