What it is

The EVESKY KZ ZST is a colourful hybrid in-ear headset that combines a balanced armature driver with a 10 mm dynamic driver. It targets listeners who want detailed highs and energetic bass in a lightweight wired form factor.

Build and connection

The earpieces use a black carbon housing made from acoustic resin and are fitted with patented silicone tips in three sizes for a secure, noise-isolating fit. A 120 cm cable terminates in a 3.5 mm L-shaped plug with 0.75 mm pins, and an inline HD microphone is included for calls.

Deciding specification

The hybrid 1BA plus 1DD driver array delivers a frequency response of 20 Hz to 20000 Hz at 18 ohm impedance and 106 dB sensitivity, making it efficient enough for direct connection to most portable sources without extra amplification.

Questions about this item

What does the 2.4 GHz ISM wireless interface mean for audio quality?

The 2.4 GHz ISM band carries the audio signal wirelessly; practical quality is limited by the 106 dB/mW sensitivity and 20 Hz–20000 Hz response of the 10 mm dynamic plus balanced-armature drivers.

What physical dimensions and connector must my device accommodate?

The cable is 120 cm long with a 3.5 mm L-shaped plug and 0.75 mm pin diameter; three pairs of silicone tips (S/M/L) are included for ear fit.

How do I install the earphones correctly, and what step is often missed?

Choose the correct tip size, seat the memory wire over the top of each ear for a locked-in fit, then insert the 3.5 mm plug fully into the jack; the HD call microphone activates automatically.
