KZ EDZ: the evolution of the EDX range
The KZ EDZ are in-ear earphones with one dynamic driver per side, the most advanced version of the EDX range according to KZ. They introduce an ultra-wideband, long-excursion driver developed by the brand and a dual damping system. They come in black or white, without microphone, with microphone and 3.5 mm jack, or with microphone and USB-C plug.

- 24 Ωimpedance
- 107 dBsensitivity

Sound
Long-excursion driver and dual damping
The driver uses high-performance neodymium magnets to move the diaphragm with more force and control, giving tight, punchy bass.
The dual damping system combines a nozzle damper and a metal filter to control sibilance and smooth the treble without losing detail.
Sound
Response from 7 Hz to 45 kHz
The stated frequency response goes from 7 Hz to 45 kHz, with 24 Ω impedance and 107 dB/mW sensitivity, so they get loud enough from a phone.
KZ tunes them to a reference curve designed to compete with much more expensive earphones.
Connection
Dual microphone and USB-C version
The microphone versions use a cable with two high-definition silicon microphones, one at the top and one at the bottom, to pick up the voice well even when the cable hangs freely.
The USB-C version includes a sound card with sound modes: standard, standard gaming, immersive gaming and Hi-Fi. The 3.5 mm version does not have it.
Connection
Detachable cable and wireless mode
The cable is silver-plated copper, 120 cm long (±5 cm), and connects with a 0.75 mm 2-pin connector. With a KZ Bluetooth adapter they can be used without a cable.
The shell is resin with a metal inlay and is worn with the cable over the ear.

KZ EDZ frequently asked questions
How does it differ from the KZ EDX Pro X?
The KZ EDX Pro X uses a super-linear driver and single damping. The EDZ introduces an ultra-wideband, long-excursion driver, dual damping and a silver-plated cable.
Which version should I choose?
Without microphone for listening to music; with 3.5 mm microphone for phones and controllers with a headphone jack; with USB-C microphone to plug them in with no adapter and use the sound modes of its sound card.
What is the advantage of the USB-C version?
It plugs straight into the USB-C port of phones, tablets and computers, with no adapter. The 3.5 mm jack versions need an adapter on phones without a headphone jack.
Do they have noise cancellation?
They do not have active noise cancellation. By sealing the ear canal with the ear tips they block outside noise passively.
