Bright-leaning with slight warmness - has an unique sparkly/lush, airy, and spacious sound. Great tech for the price, treble is not overly harsh or peaky (at mid volume), pretty smooth with the extra mid-bass balancing out the treble boost. Vocals are pushed back/not fully extended and not as prominent. Mid-volume set, doesn't scale well. Gets spicy with energetic genres past mid-volume. Great for instrumentals, acoustics, indie, classical, etc.
Youtube Video Summary

Kiwi Ears Septet lands as an airy, spacious, and distinctly sparkly listen with a clear bright-leaning tilt that avoids harshness. Despite a notable 5–8 kHz lift, the treble comes across refined rather than peaky, while a touch of mid-bass warmth keeps the tonality musical and natural. The result is punchy drums and momentum on rock and acoustic tracks, with technicals that punch above price—layering and separation sit around Dusk/Pilgrim territory. It’s like a more airy, sparklier Meta with less forward vocals and less artificial sheen than ultra-bright sets. The “open-back” faceplate doesn’t audibly change things, but staging still feels wide.

Fit and setup matter: a deep seal smooths treble; tips like Softears Alpha Clear or Tangzu Sancai can tame peaks. The Septet scales nicely on slower tracks up to ~80 dB, but on energetic K-pop/J-pop/hip-hop it can turn hot—hi-hats may sting if the volume creeps. Comfort is solid at mid volume for hours, though sensitive ears may feel fatigue over long sessions, especially in that 5–8 kHz zone. Vocals are set back: clean and inoffensive rather than shouty, but on busy rock they can feel a touch distant. This is a treble-forward, technical presentation; not a mid-centric vocal specialist and not a bass-head set—low end is adequate but softer in impact and pushed slightly to the back.

Versus peers: Astral is the safer all-rounder with more forward vocals and less brightness; Quintet is the vocal-oriented pick, while Septet is smoother, airier, and a bit more micro-detailed. Recent Orchestra Light (unit-dependent) sounds more V-shaped and shouty; Septet takes tuning and technicals. Odyssey wins on immersion, bass texture, and vocal pop at loud volumes, but Septet brings better air, separation, and detail at normal levels. Compared with Lush, Septet is brighter and more resolving; Lush is smoother and one of the best scalers under $300 if you like it loud. For vocals first, look to EPZ P50, Cadenza 4, or Tanjim Origin; for bassier fun under $300, consider DSKO, Estrella, Deuce, or Tros. If a sparkly, airy, technical flavor that stands apart from “Harman-by-default” is appealing, Septet is a worthwhile add to the collection.

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.

A unique open back iem.
Youtube Video Summary

The Kiwi Ears Septet is a multi-driver oddball in the best way: a single DD + 4BA + planar + PZT hybrid with an open-back shell at $259. Build is solid with a metal body, flat 2-pin sockets and a handsome modular cable; fit is stable and isolation would be strong if it weren’t vented. It’s clearly aimed at listeners who want something different in both design and presentation.

Sonically it’s a down-tilted, slightly L-shaped tuning: deep, thumpy bass, subdued upper-mids, and a sparkly 4–6 kHz region that adds air and detail. The open structure creates a speaker-like stage—wide, clean imaging with a sense of room—but it can show a hint of hiss and benefits from more power (dongle/DAP recommended) to wake up dynamics. It’s a unique, spacious listen that some will love and others won’t; while the treble and imaging impress and it earns a recommendation (even a spot in a price-tier top 10), those wanting stronger presence in vocals may prefer Kiwi Ears’ more conventional tunings or adjacent sets like Astral or Performer series.

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.

The Kiwi Ears Septet delivers a neutral-bright sound signature characterized by clear vocals and a notably forward treble that enhances detail retrieval, particularly in female vocals and acoustic instruments. Its bass response is neutral and controlled, lacking the weight of closed-back designs but offering tight, fast decay. While this tuning excels with well-recorded tracks, it can become fatiguing with bright or poorly mastered material due to its upper-midrange and treble emphasis. The open-back design contributes to an airy presentation, though it reduces isolation significantly.

Technically, the Septet showcases a wide soundstage with precise imaging and strong microdynamics, allowing subtle instrumental textures to shine. Its seven-driver quadbrid configuration (dynamic, balanced armature, planar, and piezoelectric) integrates cohesively through a sophisticated 5-way crossover. However, the low sensitivity (95dB) demands powerful sources to avoid dynamic compression, and the open-back design makes it less suitable for noisy environments despite its comfortable fit.

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.

A very unique tuning with very clean bass and mids and a subdued, understated vocal presentation. Low and mid treble is boosted quite a bit. Can be Fatiguing. A True open-backed IEM that leaks sound and isolates very poorly. Super nice shells and cable. Wish the treble wasn't so harsh and the vocals weren't so recessed

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.
