Epz K9 VS Final A5000

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.

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.

Much improved over the A4000, which actually gave me a headache. Bass is fun and decently textured. Good punch and slam with good tactility. Mids are decent - the delayed pinna gain or recessed mids (however you want to call it) detracts from timbre a bit but there is a good amount of clarity. Treble is decent - while it can sometimes teeter on being a bit shouty, it's never too much - could use a bit more extension. I don't hear the "immense stage and amazing imaging" that some folks say they hear in the Final A series of IEMs but stage and imaging are slightly above average for IEMs. I think these would actually be pretty competitive if they were priced better - it's not a bad IEM. Unfortunately, at $280 these are a hard sell given the state of the market these days. If you can find a set for closer to $200, they become much more compelling. Great alternative to the Harman/neutral with bass boost bandwagons.
