Hybrid driver design

The KZ ZST pairs a 10mm dynamic driver with a balanced armature in each earpiece. This hybrid arrangement handles bass and treble through separate physical paths. The 18ohm impedance and 106dB sensitivity allow direct connection to portable sources without extra amplification. Multicolor resin housings distinguish the set visually.

Wired 3.5mm constraints

A fixed 3.5mm L‑shaped plug and 120cm cable tie the listener to the playback device. The 0.75mm pin diameter on the detachable cable end is proprietary, so third‑party replacements must match that exact specification. Passive noise isolation depends entirely on the fit of the included silicone tips; no active cancellation circuitry is present.

Resin build and daily fit

Acoustic resin shells keep weight low while the memory‑wire ear hooks curve over the ear for a locked‑in feel during movement. Three pairs of patented silicone tips in small, medium and large sizes ship in the box, letting the user swap for the best seal. The removable cable eases storage and allows replacement if the lead frays.

Questions about this item

Should I pick the version with a microphone or without one?

Both versions share the same 10 mm dynamic plus balanced-armature driver, 18 ohm impedance, 106 dB sensitivity and 120 cm cable; the only difference is the inline microphone.

How loud will these get with a typical phone output?

At 106 dB per milliwatt and 18 ohms they reach high volume easily from a smartphone 3.5 mm jack without needing an external amplifier.

What does the 3.5 mm L-shaped plug mean for daily use?

The right-angle 3.5 mm connector reduces strain on the socket and fits most phones, laptops and portable players that still offer a headphone jack.
