Hybrid Driver Configuration

The KZ ZST Colorful combines one balanced armature and one 10 millimetre dynamic driver in each earpiece. This hybrid arrangement separates frequency duties so the armature handles higher detail while the dynamic unit covers lower tones. The result is a single in-ear monitor suited to listeners who want distinct instrument separation without adding a second pair of headphones.

18 Ohm Impedance and 106 dB Sensitivity

With an 18 ohm load and 106 dB sensitivity the earphones reach usable volume from a standard 3.5 millimetre jack on phones, laptops or handheld consoles. No external amplifier is required for typical mobile use. Buyers who need balanced outputs or plan to drive them from high-impedance studio gear should look elsewhere.

Memory Wire and Patented Silicone Tips

A pre-shaped memory wire loops over the ear to lock the fit during movement, while the supplied TPE silicone tips in three sizes seal the canal for passive isolation. The cable terminates in a 3.5 millimetre plug and is user-replaceable. Users unfamiliar with over-ear routing may find the initial adjustment fiddly, and the thin cable can transmit handling noise if it brushes clothing.

Questions about this item

How loud will the 106 dB sensitivity make music sound in my ears?

At 106 dB sensitivity the earphones produce a high volume from a typical phone or laptop output, so you can reach loud listening levels without needing a separate amplifier.

What does the 18-ohm impedance mean for the devices I can plug them into?

The 18-ohm load is easy for smartphones, laptops and portable players to drive, so you will get full volume and consistent frequency response from most 3.5 mm sources.

Will the 10 mm driver housing and 3.5 mm plug fit my ears and devices?

The 10 mm driver units sit in a lightweight 2.3 g shell with memory-wire hooks that wrap behind the ear, and the 3.5 mm connector fits any standard headphone jack.
