The Jays Audio x ZiiGaat Estrella delivers a thrilling V-shaped signature that prioritizes fun and engagement. Its standout feature is the commanding sub-bass, powered by dual dynamic drivers, which delivers seismic rumble and physical impact without bleeding into the mids—perfect for bass enthusiasts seeking both power and control. Mids remain clear and forward enough for vocals to cut through, though they occasionally take a backseat to the low-end spectacle, leaning toward a warm, lush presentation.
Treble shines with energetic sparkle and strong extension, enhancing micro-details and air, though its peakiness can induce fatigue in longer sessions or with bright tracks. Technically, the Estrella impresses at its price with expansive soundstage width, precise imaging, and detail retrieval rivaling costlier models, though timbre can occasionally skew artificial in complex passages. The lightweight resin shells ensure comfort, but the accessory package disappoints—the flimsy stock cable and mediocre tips demand aftermarket upgrades.

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 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.
