A Tech

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.

The Technics AZ80 delivers a warm sound profile with a well-balanced bass boost and mostly flat mids, providing crisp vocal and instrument reproduction. Its 10mm free-edge dynamic driver supports LDAC for high-resolution audio, though the passive soundstage feels somewhat confined . The standout feature is three-device multipoint connectivity, enabling seamless switching between multiple sources, though LDAC streaming is restricted to two devices simultaneously . Battery life reaches 7 hours with ANC active, extending to 24 hours via the case, and Qi wireless charging adds convenience .

Active noise cancellation is effective for low-frequency rumble like plane engines but trails class leaders like Sony and Bose in mid-range attenuation . Transparency modes include a standard ambient option and a voice-focused "Attention" setting, though both sound less natural compared to AirPods Pro 2 . Call quality is inconsistent: the JustMyVoice technology with eight mics suppresses background noise effectively but can render voices thin or muffled in noisy environments .

Comfort is a strong suit thanks to the ergonomic concha-fit design and seven included ear tip sizes, ensuring stability during workouts or travel . However, the bulky earbud chassis may cause fit issues for smaller ears, and the circular nozzle design can compromise seal for some users . At $299, they face fierce competition from rivals with superior ANC or more compact designs, though their unique triple multipoint and expansive tuning remain compelling for multitaskers .

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

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.

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.
