FAQs.

Q Who is the EPZ K5 for?

K5 is for listeners who want a clear, detailed presentation without losing musicality. It fits daily listening, long sessions, and anyone upgrading from basic earphones.

Q What is the driver configuration?

K5 uses a 1DD + 4BA hybrid design for better separation across bass, mids, and treble. The dynamic driver anchors the low end, and the BA drivers focus clarity and layering.

Q Is K5 easy to drive?

Yes. With 28Ω impedance and 114dB sensitivity, it plays well from phones and most portable sources.

Q What connectors does it use?

K5 uses a 0.78mm 2-pin detachable cable. It includes a 2-in-1 plug system with 3.5mm and 4.4mm options for different sources.

Q What is the shell made of, and how is the fit?

The shell uses a 3D-printed resin cavity designed for comfort and stable wear. It is shaped for long sessions and everyday portability.

The dynamic driver utilizes a Liquid Crystal Polymer and Polyurethane composite diaphragm to ensure lightning fast transient response. This advanced material creates impactful and textured bass that stays tight and controlled. It provides a solid foundation for your music without overwhelming the delicate mid frequencies.

Experience the best of both worlds with our hybrid acoustic architecture. A powerful dynamic driver handles deep low frequencies while four custom balanced armatures deliver crisp vocals and airy treble. This synergy creates a holographic soundstage that puts you right in the center of the performance.

Our high purity cable comes with interchangeable gold plated plugs to suit all your devices. You receive both standard single ended and balanced connectors in the box. This versatile design allows you to drive the earphones to their full potential using any professional player or amplifier.

Crafted using industrial high precision printing technology each shell is shaped for superior ergonomics and noise isolation. We use medical grade resin that is smooth against the skin and highly durable. The result is a custom like fit that remains comfortable even during marathon listening sessions.

The 5-driver matrix works as one. We eliminated the disjointed sound of traditional hybrids, delivering a smooth, unified transition from deep bass to airy treble.

I am satisfied with the headphones! They were well packaged, it's clear that the seller cares about the customer. The packaging is reliable and the headphones arrived in perfect condition.
I chose them in green and they look simply fantastic! Separate "wow" for the transparency of the case: you can see all the "filling" of the headphones, which adds them to uniqueness and technical attractiveness-you can sit and look at the insides.
The earphone body itself is small and convenient, they are lightweight, sit perfectly comfortably in the ear, and this is also thanks to the rich set of ear pads. For me, the "Christmas tree" ear pads were a perfect fit, providing maximum comfort and sound insulation.
I would like to mention a great case — it's compact, stylish, and well-made.
The sound "out of the box" is good! I switched from dynamic models to these and am still getting used to the new sound character. It's very interesting to see how they will unfold after warming up.
Overall, this is a great purchase that I am very satisfied with! I recommend!

Gorgeous headphones in terms of price-quality ratio. 👍

All is good and perfekt. Thanks only the box is small.

if you need light, air, spatial sound, then you are here. just wonderful headphones, especially for that price. It should be taken into account that the bass shelf has been reduced and there is a early drop on itself, but without this we would not have achieved such an open sound. Nevertheless, the headphones are musical and there is a mass on the bass, but the volume is reduced. There are headphones that are twice as expensive, but in my opinion they are at the same level as k5. The cable here is better than hybrid or good copper. Silver or graphene will be illuminated without that light sound. It seems that the new versions already come with a copper cable. The ear pads have to be tightly pulled on a long ear pad. Suitable with wide soles, like epz m100. If they were included in the kit, instead of garbage rubber bands, it would be much better.
