Open, Layered, Controlled.

K9 creates room inside the music. Vocals, instruments, and low-end energy stay separated and stable, so even complex recordings feel organized instead of congested.

It is a sound that gives every element space to breathe.

A Hybrid That Speaks as One.

With one dynamic driver and eight custom balanced armatures, K9 delivers impact, nuance, and extension in a single coherent presentation.

You get the scale of a flagship hybrid without the disconnected feel that multi-driver designs sometimes bring.

Detail Without Fatigue.

Thanks to its 3-way dual crossover architecture, K9 resolves subtle information with calm control.

Notes feel refined, transitions stay smooth, and long listening sessions remain exactly that—long.

Ready for Portable or Balanced.

K9 is easy to integrate into real listening habits.

Its 14Ω impedance, 108dB sensitivity, and modular 3.5mm / 4.4mm plugs make it simple to move from dongle DAC to DAP to desktop chain without changing the experience.

Flagship Presence, Natural Fit.

The dragon-scale faceplate gives K9 a distinctive visual identity, while the resin shell stays smooth and comfortable in the ear.

It looks like a statement piece, but it wears like something made to disappear.

FAQs.

Q Who is the EPZ K9 designed for?

K9 is for listeners who want a flagship hybrid with strong separation and a smooth, coherent presentation. It works well for focused music listening and everyday use across genres.

Q What is the driver configuration?

K9 uses 1DD (10mm LCP+PU) + 8 custom balanced armatures. The dynamic driver anchors bass weight, and the BA array supports vocal detail and treble layering.

Q Is it easy to drive?

Yes. K9 is rated at 14Ω impedance and 108dB sensitivity (±3dB), so it pairs well with portable sources. A clean dongle DAC can help keep the background quieter at higher volume.

The stock cable uses a modular plug system with 3.5mm single-ended and 4.4mm balanced options. You can switch outputs in seconds and keep one cable for different sources.
